Today's Game Notes
  • Two MLB starts hardly constitute a significant sample size, but based on the eye test, Sixto Sánchez is making a statement so far. The 22-year-old right-hander not only is showing that he belongs in the big leagues, but he is also proving that he has the makings of an ace. The way Sánchez dominated the Rays, with 10 strikeouts in seven innings, reinforced that the Marlins’ top prospect has a bright future. What he lacked in the series opener in the Citrus Series was run support.

    Yandy Díaz’s two-out RBI single off Brad Boxberger in the eighth inning opened the scoring as the Rays topped the Marlins, 2-0, on Friday at Marlins Park.

    “He was really good,” Marlins manager Don Mattingly said of Sánchez. “He was kind of in control all night. Used his changeup a lot. Was able to elevate. He gives you seven innings of scoreless. He gives us a chance to get on the board. We just weren't able to get on the board for him.”

    Sánchez, who scattered six hits and walked one, was not involved in the decision. He was locked in a duel with Rays lefty Ryan Yarbrough, who exited with left groin tightness after 6 2/3 shutout innings.

    “That was some impressive stuff,” Rays manager Kevin Cash said of Sánchez. “He was able to land his offspeed pitches. He established the fastball and he had a wipeout changeup. He is pretty talented.”

    According to Statcast, Sánchez’s maximum fastball velocity was 100.6 mph, and he had 13 pitches at 99 mph or higher. Of his 92 pitches, 17 were swinging strikes, with eight coming on his changeup.

    “I will say it's my main pitch, my changeup,” Sánchez said through an interpreter. “I'd say my second one is my fastball. I truly trust my changeup a lot. I use it to get ground balls and get outs, get double plays. I do trust my changeup a lot.”

    MLB Pipeline’s No. 24 overall prospect, Sánchez has displayed plenty of confidence in his first two starts, challenging hitters while displaying emotion on the mound.

    “When I'm like that during the game, it actually helps me a lot to throw my pitches with high emotions,” Sánchez said. “I just use that to do a good job in the game.” (J Frisaro - - Aug 28, 2020)

  • Sept 2, 2020: Effective. Efficient. Electric.

    Sixto Sánchez was all of the above in his third big league start. But in the fifth inning, he wasn’t exactly precise on a slider, and it cost him.

    Lourdes Gurriel Jr. connected on a two-run homer off Sánchez, and that was the difference as the Blue Jays edged the Marlins, 2-1, to gain a split in the two-game Interleague series at Marlins Park.

    The Marlins (16-16) had chances off Hyun Jin Ryu, but they scratched out just one run in six innings. Miami went 1-for-10 with runners in scoring position and left nine on base.

    As a result, Sánchez took a loss for the first time in his young MLB career. He is 1-1 with a 2.37 ERA. In his last two starts, he has allowed only two runs in 14 innings, but the Marlins have lost both times.

    As impressive as Sánchez’s stat line looked -- two runs on six hits with no walks and five strikeouts on 79 pitches over seven innings -- Miami manager Don Mattingly noted the rookie wasn’t as dominant as in his previous outings.

    “That's like the least I've seen him,” Mattingly said. “I feel like he made a lot of mistakes around the high thigh. A lot of balls I think he got away with some pitches. But he changes speeds, and that tells you what kind of guy he is when he's not the guy who was dominant the other day. But still, obviously, really good.”

    In his last outing, Sánchez tossed seven shutout innings in a no-decision against the Rays. The 22-year-old right-hander kept the Blue Jays off the board until the fifth, when Gurriel connected on a hanging slider for a two-run homer.

    “I was trying to throw the pitch, low and outside, and it actually did the opposite,” Sánchez said through an interpreter. “It went low and inside. It happened. Things happen in baseball.”

    According to Statcast, the drive to left-center projected at 408 feet, with an exit velocity of 103.3 mph. Rowdy Tellez had a broken-bat single that set up Gurriel’s blast.

    The homer snapped a string of 11 straight scoreless innings by Sánchez.  (J Frisaro - - Sept 2, 2020)

  • September 8, 2020:  6 IP, 3 H, 0 R, 0 ER, BB, 6 K, HBP

    With his sixth pitch of the game, Sixto struck out Ronald Acuña Jr. swinging on a 100.2 mph fastball. The pitch also was a message that the rookie right-hander was going to be on the attack.

    Making his fourth big league start, Sánchez was in command in six-plus innings, striking out six in the Marlins’ 8-0 victory over the Braves at Truist Park.

    “You could sense the excitement because we've been talking about Sixto for a couple of years,” Marlins manager Don Mattingly said. “And then to see it get here. I think we did a good job making sure he was built up, so he didn't come here with rules. From the standpoint of, he can only do this. You have to watch his pitch count. You were able to build him physically and give him the best chance to go and be one of the guys.

    “He has definitely brought an excitement to our rotation, and he continues that competition that we want with all of them in a healthy way,” Mattingly said. 

    Sánchez allowed just three hits, walked one, hit a batter and exited only after appearing to run out of gas on 89 pitches in the seventh inning. He threw 60 strikes, including two that were tracked by Statcast at 100 mph or higher. Also in the first inning, he blazed a 100.6 mph fastball that Marcell Ozuna fouled off.

    "I’m telling you what, if he stays healthy, he’s going to give people fits for a long time," Braves manager Brian Snitker said. "That’s the total package right there." (Frisaro -

  • Sept. 14, 2020: Rookie Power Rating #4. Sixto Sánchez

    Sánchez has been every bit as advertised during the first month of his career, going 3-1 with a 1.69 ERA, 0.91 WHIP and 29/5 K/BB in 32 innings (five starts). He tossed a complete game against the Phillies on Sunday, limiting his former organization to one run on three hits over seven innings in Game 1 of a doubleheader. The 22-year-old righty picked up his fourth and final strikeout when he blew a 100.4 mph fastball by Alec Bohm for the first out in the seventh inning. That one pitch put Sánchez in elite company, as he became just the 11th starting pitcher since 2008 to record a strikeout on a 100-plus mph pitch in the seventh inning or later.

  • MLB Prospect Watch: Sept. 23, 2020

    Most Productive Pitcher: Sixto Sanchez, RHP, Marlins

    For a relatively young franchise, the Marlins sure have had their share of phenom pitchers. Sanchez might be the latest one, as he's looked the part in an admittedly small sample. He's demonstrated that he has a deep arsenal, and a strong feel for both throwing strikes and changing speeds. The main concerns that scouts had about him -- his height and inability to miss bats with his fastball in the minors -- either haven't mattered or haven't carried over to his big-league stint. If the Marlins make the playoffs, there's a real chance that Sanchez could force a higher seed to win consecutive games in order to advance. (R.J. Anderson)

  • In 2015, Sanchez signed with the Phillies (see Transactions below).

  • Sixto originally trained in the Dominican Republic as a shortstop, but his arm was better than his bat, so he moved to the mound. At a tryout for a Cuban catcher, the Phillies were instead drawn to Sanchez, an eligible 16-year-old pitcher who had quick, easy arm action and a fastball that reached the low 90s. 

    One day, back in 2015, the Phillies held a tryout for a Cuban catcher named Lednier Ricardo at their Dominican academy in Boca Chica. Sanchez was there to throw batting practice to Ricardo, but the Phillies liked Sixto's easy velocity and passed on the Cuban backstop.

    A couple days later, Sanchez—who was just 16 years old—got the news.

    "The Phillies called my father,” Sanchez said. "My father was laughing.”

    Sanchez’s father was joyous because his son was offered—and quickly accepted—a $35,000 bonus, which goes a long way in the Dominican Republic.

    Sanchez, who has four sisters and three brothers, quickly made his family even prouder by dominating Rookie-level Gulf Coast League competition in his U.S. debut in 2016. He shot to No. 5 on the Phillies' prospect ranking that offseason.

    Phillies special assistant Bart Braun was at a workout in the Dominican Republic to scout a Cuban catcher. The player who caught his eye was Sanchez, the 16-year-old pitcher throwing to him, so the Phillies moved quickly to sign him.

  • In 2016, Sixto claimed the ERA title (0.50 ERA and only 4 runs in 11 starts) for the Gulf Coast League in 2016. And after that, he finished off his season with seven scoreless innings in the GCL playoffs.

  • In 2017, Baseball America rated Sanchez as the 5th-best prospect in the Phillies farm system. They had Sixto at second-best prospect, behind only J.P. Crawford, in the spring of 2018. And in the winter before 2019 spring camps opened, Sanchez was the #1 prospect in the Phillies organization, then stayed number one in the spring of 2020.

  • July 2019: Sixto represented the Marlins at the Futures All-Star Game. He was also named MVP for Jacksonville.

  • 2019 Season: Sanchez (the Marlins’ No. 1 prospect, and No. 23 overall, per MLB Pipeline) received the Double-A Jacksonville Most Valuable Player Award.

    Sanchez, acquired from the Phillies in February as part of the J.T. Realmuto trade, completed his first season in the Marlins organization, and the hard-throwing righty showed he was healthy after a right elbow issue limited him in 2018. The 21-year-old was 8-4 with a 2.53 ERA in 18 starts for Jacksonville, and he added two more starts at Jupiter. Overall, he was 8-6 with a 2.76 ERA in 20 starts and struck out 103 and walked 21 in 114 innings.

  • Jan 13, 2020: No player currently on the Marlins’ 40-man roster has been assigned the No. 45. The organization just may be holding the number for when top prospect Sixto Sanchez is ready to reach the big leagues. To sport 45 on the back of his jersey would be special for Sanchez, because that’s the number Pedro Martinez, his childhood idol, wore. Like so many pitchers born in the Dominican Republic, Sanchez was raised admiring Martinez, the Hall of Fame right-hander and personable baseball figure who continues to be in the public eye as a TV analyst.

    “Since I was little, I’ve admired him, seeing all his games,” Sanchez said in Spanish. “I always said, ‘Wow, I want to be like him.'"

    Sanchez spoke to at MLB’s annual Rookie Career Development Program, held in Miami. The right-hander is one of the top pitching prospects in the game, and he is tracking toward reaching the big leagues in 2020.

    When it comes to his main goal this year, Sanchez makes his intentions clear: “To keep working hard and to be able to get to the big leagues.”

    Ranked by MLB Pipeline as the Marlins’ No. 1 prospect, and No. 22 on the overall Top 100 list, Sanchez will be one of Miami’s most closely monitored players when Spring Training opens on Feb. 12 at the Roger Dean Chevrolet Stadium complex in Jupiter, Fla.

    The 6-foot, 185-pound Sanchez is a hard-throwing right-hander with a fastball that routinely reaches 100 mph. The 21-year-old is already on Miami’s 40-man roster, and he’s been assigned No. 73 for Spring Training. Players who have yet to reach the big leagues often have high numbers in Spring Training before they make it.

    But when Sanchez does reach Miami, he can request another number. And since 45 is not already taken, it’s safe to assume it may be reserved for the Marlins’ top prospect. Still, the right-hander may have to wait a little while. (J Frisaro - - Jan 13, 2020)

  • MLB debut - Aug. 23, 2020: At 7:50 p.m. ET, Marlins top prospect Sixto Sánchez fired his first MLB pitch, a blazing 98.4 mph fastball taken for a strike by Trea Turner. It marked what many believe will be the beginning of a promising career.

    For a first impression, Sánchez came as advertised, bringing heat -- five pitches touched or topped 100 mph -- while striking out four in five innings in the Marlins’ 5-3 victory over the Nationals in Game 2 of Saturday's doubleheader at Nationals Park.

    “It was everything I expected this to be,” Sánchez said through an interpreter. “I've worked so hard for this day to come, and it was actually what I expected. My confidence grew a lot after I threw my first pitch. I thought I was going to throw a ball, but I threw a strike. After that, it was good.” (Joe Frisaro)


  • February 20, 2015: Sanchez signed as a free agent with the Phillies, out of the D.R., via scout Carlos Salas. His bonus was only $35,000, via scout Carlos Salas.

  • Feb. 7, 2019: Philly made a big splash by acquiring Marlins catcher J.T. Realmuto in exchange for top prospect Sixto Sanchez, catcher Jorge Alfaro, pitching prospect Will Stewart, and $250,000 international slot money.
  • Sanchez has good command of his very lively 93-101 mph FASTBALL with solid sink and arm-side run, generating weak contact for a 70 grade on the 20-80 scouting scale. He also has a 60 grade 88-90 mph power SLIDER with two-plane tilt that misses both left- and righthanded bats and is a 60 grade. And his CHANGEUP runs away from lefty hitters, sinking beneath their bats with impressive downer drop, flashing 60, on the 20-80 scale. He sells that change with the same arm speed as his heater.

    Sanchez's combination of stuff and command belongs in the discussion of the best among pitching prospects. His fastballs feature a two-seamer that produces power sink and a four-seamer that climbs into triple digits. His best secondary offering is a changeup that dives at the plate, and he also has good feel for manipulating a hard slider that can be a plus pitch at times.

    Sanchez has pounded the strike zone ever since he entered pro ball, displaying an easy, repeatable delivery that helps diminish concerns about durability despite his smaller frame. While he hasn't missed as many bats as his stuff suggests he should, he posted a 4.6 K/BB ratio and a 1.4 groundout/airout ratio in his first five Minor League seasons. As long as he stays healthy, he has the ingredients to become Miami's best starter since the late Jose Fernandez.(Spring 2020)

    Some scouts worry about Sanchez’s stuff holding up as a starter because of his size; other scouts don’t because of his athleticism. He has 60 grade control.

  • Sixto has a relatively clean, smooth delivery -- easy and athletic.

  • Sixto has advanced pitch-ability that allowed him to toy with lesser hitters while saving his focus for the middle of the order and big situations.

    Sixto is athletic and in control. He has such "easy heat." He doesn't have to have his arms and legs flailing to distract hitters via deception and muscle the ball to the plate. And that allows him to command the ball well.

    It is just very rare to see such a young pitcher who combines exceptional velocity along with advanced control and impressive command. He gets a 70 grade for his command.

    Sanchez is one of the hardest-throwing starting pitchers in the minors, but you wouldn’t know it from his delivery. He has easy, fluid mechanics that he repeats consistently. He is gaining a understanding of how to sequence hitters. (Spring 2019)

  • Sixto is a smallish righthander with impressive command for such a young guy. And he can pitch to all four quadrants of the strike zone.

    Hitters just don't seem to make much solid contact off Sanchez. You have to marvel at the ease with which he generates power from his textbook delivery. Similarly, his ability to command his power fastball is impressive. He has a loose, quick arm.

    “He’s got a tremendous arm,” Philles minor league pitching coordinator Rafael Chaves said. “His fastball is 96-99 (mph) and he can change speeds.”

    Sanchez’s poise and mound presence are that of a veteran pitcher, not someone who moved from shortstop to the mound in 2014.

    “His feel for pitching is amazing,” Chaves said. “The poise he showed and how he dominated the league this summer was impressive.” (Spring, 2017)

  • Sanchez has a shot at being a #1 or #2 starter in MLB. He gets some comparisons to the Yankees Luis Severino. He just needs to show he can handle a starters' workload.

  • 2018 Season: Sanchez has one of the most electric arms of any pitching prospect in baseball, with the chance to have three above-average to plus pitches when all is said and done. But his climb to the top of the pitching prospect rankings was slowed by elbow inflammation in 2018, limiting him to just 46.2 innings. Sanchez did not pitch after June 3.

  • Sixto has a very impressive right arm.

    "He has uber-weapons,” Jacksonville manager Kevin Randel said. "He has an electric arm—fastball, slider and changeup, all for strikes, superb control. He’s poised beyond his years.”

    Sanchez reached at least 99.6 mph on five of the eight fastballs he threw at the 2019 Futures Game in Cleveland this year. His average fastball velocity of 99.3 mph was second-best at the event.

    "No moment is too big for him,” Randel said. "He loves the spotlight."

  • 2019 Season: Sixto Sanchez, RHP (No. 1/MLB No. 22). Sanchez reached Double-A and threw a career-high 114 innings (with 103 strikeouts) in the 2019 season. The 21-year-old throws both a two- and four-seam fastball, can touch triple digits and also throws an above-average breaking ball and changeup.

  • Jan. 14, 2020: Sanchez was named one of the top 10 MLB pitching prospects entering the season. His best pitch is his change-up which he developed as a teenager. He is also noted for his control. It is one of the reasons he reached Double-A at age 20. 

  • 2020 Improvements: Sixto Sanchez is throwing off the mound, showing off his usual triple-digit fastballs — both a four-seamer and a sinker — to go along with his above-average changeup as he faces some of the Miami Marlins’ top hitting prospects at their alternate training site in Jupiter.

    Another pitch is in the works to round out his arsenal.

    Sanchez, the Marlins’ top prospect and the No. 22 overall prospect across MLB according to MLBPipeline, said Sunday he has started to throw a curveball instead of his slider over the past few weeks since team practices resumed. (JORDAN MCPHERSON - JULY 19, 2020)

  • Aug 28, 2020:“He was really good,” Marlins manager Don Mattingly said of Sánchez. “He was kind of in control all night. Used his changeup a lot. Was able to elevate. He gives you seven innings of scoreless.

      “That was some impressive stuff,” Rays manager Kevin Cash said of Sánchez
    . “He was able to land his offspeed pitches. He established the fastball and he had a wipeout changeup. He is pretty talented.

    According to Statcast, Sánchez’s maximum fastball velocity was 100.6 mph, and he had 13 pitches at 99 mph or higher. Of his 92 pitches, 17 were swinging strikes, with eight coming on his changeup. (J Frisaro - - Aug 28, 2020)

  • Sixto is a very solid fielding pitcher. He's an extra infielder when he's on the mound.
Career Injury Report
  • June 9, 2018:  Sanchez went on the disabled list with inflammation in his right elbow. His season was mostly shelved because of lingering tenderness in his elbow. 

  • October 10, 2018: The Phillies hoped Sanchez, their top prospect by MLB Pipeline, could make up for lost time in the Arizona Fall League. But he was set back due to problems with his collarbone.

    A Phillies source said team doctors are not concerned. Sanchez is the No. 21 prospect in baseball. He has not pitched since June because of inflammation in his right elbow. The Phillies' window to get him stretched out and ready to compete this fall did not allow for setbacks, but Sanchez recently reported soreness in his clavicle. The source said the Phillies then decided to be conservative and remove him from the AFL roster.

  • 2019: Sanchez has recovered from the shoulder inflammation that cut short his 2018 season and delayed his 2019 campaign by one month.
