In 2012, Rosario signed with the Mets (see Transactions below). 

Amed has both athleticism and aptitude on display. He devours information and applies it very quickly.

In 2013, Baseball America rated Rosario as the 28th-best prospect in the Mets' organization. Amed moved all the way up to 7th-best prospect in the Mets' farm system in the winter before 2014 spring training.

They had Amed at #6 in the spring of 2015, then moved him up to second-best prospect in the Mets' organization in the spring of 2016, behind only Steven Matz. And then, in 2017, they had Rosario as the #1 prospect in the Mets' farm system.

As a youth in Santo Domingo, Amed was teammates with Rangers right fielder Nomar Mazara.

Jan 13, 2023: Bieber and the Guardians avoided arbitration, agreeing to a one-year deal for $10.01 million. 

Amed graduated from high school before turning pro. His father, who was a lawyer and a judge, helped steer the signing process.

In 2016, Rosario earned MLBPipeline.com's Mets Prospect of the Year honors.

“The thing, I think, that also excited us was he decided against playing winter ball because he wanted to work on just getting stronger,” Ricco said. “He recognizes that’s really what he needs as opposed to playing more in the offseason.” (Jan 2017)

Jan 14, 2017: As Rosario has developed from an intriguing prospect to one of baseball's best, he has leaned at various points along the way on a few people in particular.

One, was Jose Reyes. The two crossed paths for about two weeks, when Rosario was playing at Double-A Binghamton and Reyes was working his way back into big league shape there. They snapped pictures together, posting them on social media. Both men came away impressed.

"For me, it was a tremendous experience, because Reyes is my favorite player, and he taught me and helped me a lot during those few games we played together," Rosario said at the Major League Baseball Rookie Career Development Program in Leesburg, Va.

"Really, I thank God, who gave me the opportunity," Rosario said. "For me, it's a pleasure to play being a few years younger in each level I've played in. I feel good about that."

With Reyes and Asdrubal Cabrera entrenched at shortstop this season, the Mets want nothing more from Rosario than another solid year of development. After that, anything is possible for a team that has been searching since Reyes for its shortstop of the future. (A DiComo - MLB.com - Jan 14, 2017)

In 2017, Rosario represented the Mets in the All-Star Futures game.

MLB debut (Aug 1, 2017): When Amed was told of his promotion to the Mets, the first person he called was his sister. Rosario's sister has been living with him in Las Vegas, and Rosario was on his way to English class when he got the call. But he had to make her promise not to tell anyone else, as he wasn't technically allowed to say anything.

"They told me I couldn't say anything until it was shared with a press release," Rosario said through an interpreter prior to making his Major League debut.

The shortstop went 1-for-4, notching his first career hit on an infield single in the eighth inning.  Per Statcast, Rosario's sprint speed was 30.6 feet/second on that hit, and he went 4.04 seconds home-to-first, both considered elite.

"It was a tremendous experience just being out there," Rosario said after the game. "I really don't have words to describe it." (Gelman - mlb.com - 8/1/17)

Aug 11, 2017: It was Rosario's first, and he made it count. Just minutes after the Phillies climbed back to tie the game in the eighth, Rosario smacked his first career big league homer, a go-ahead shot in the ninth, to propel the Mets to a 7-6 win at Citizens Bank Park.

"I've been seeing that stuff all year," Smith said of Rosario. "I'm finally glad that he can show everybody that stuff, playing on TV every day. I'm just extremely happy for him. He worked extremely hard to get to this point, and you all can see that." 

Added Rosario: "It's just a dream come true." (A Dicomo - MLB.com - Aug 12, 2017)

In 2017, Rosario won the Pacific Coast League’s Rookie of the Year.

In 2017, Rosario was named the Mets Triple-A Player of the Year.

Nov 29, 2017: While the holidays are a break until pitchers and catchers report, some teams and players are doing their part by giving back to the community in a big and fun way. The Mets took the time to take some kids on a shopping spree for the holidays, and it was adorable … with a bit of flair.

The Mets Annual Shopping Spree was underway and at the center of it all were Amed Rosario and Dominic Smith. Smith took his friend David under his wing and spoiled him with so many toys and clothes that the shopping cart could barely fit it all. And as far as Rosario, well he also gave his little buddy a shopping spree, all while showing off some serious Christmas swag in the process.

That's the most Christmas-y Christmas jacket we have ever seen. Good look winning the best-dressed award at your holiday party going up against those two. (J Kleinschmidt - MLB.com - Nov 29, 2017)

Nov. 2018: Rosario was on the MLB roster for the Japan All-Star Series with Nippon Professional Baseball (NPB).

Dec 13, 2018: Sometimes dreams do come true, like when you get that Official Daisy Red Ryder BB Gun you always wanted. Amed Rosario's Christmas wish took a little longer. Rosario shared a photo with his new Mets teammate, Robinson Cano. But this photo wasn't snapped at a recent Mets event. Rather, it was when Rosario was a teenager in the Dominican Republic. Rosario had actually tracked down Cano that day in order to meet the star.

"It was a great experience being so young and being around a superstar baseball player,'' said Rosario to the New York Post. "I never expected to play with him, but baseball is very small. Now that Cano is here, I'm happy." (M Clair - MLB.com - Dec 13, 2018)

Amed is the Mets' member on the Taylor Hooton Foundation advisory board, the foundation which advocates against the use of appearance-enhancing and performance-enhancing substances by the youth of America.

"It's a privilege to be a part of this organization, especially being a Latin player," Rosario said. "It's an interesting program overall, and I'm just happy to be able to be an influence and part of it.  It's something that I'm very happy to be a part of," Rosario said. "It comes from a family thing where I've always been brought up to try and give back, and the little I've made so far, it's something I'm trying to give back."  (DeNicola - mlb.com - 5/19/19)

2019 Season: Rosario had a breakout season with the Mets. He slashed .287/.323/.432 with 15 homers, 72 RBIs, and 19 stolen bases.

Roomies!  Spending his quarantine in the Tampa, Florida area, Amed had a unique living arrangement, sharing a home with Tigers infielder Willi Castro. The two have known each other since 2012 and became brothers-in-law when Castro married Rosario’s sister, Aniana. Rosario is now an uncle to their daughter.

“Me and Willy have a tremendous relationship,” Rosario said. “He really is like a brother to me.” (Anthony DiComo - July 8, 2020)

2020 Season: During the abbreviated season, Rosario produced a slash line of just .252/.272/.371 with only four homers and 15 RBIs in 46 games. After swiping 43 bags the previous two seasons, Rosario failed to swipe a base in 2020, and had only one attempt.

2022 Season: He hit .283/.312/.403 in 670 plate appearances this season, bringing his collective output in two seasons with Cleveland to .282/.316/.406. By most metrics, this was also his best defensive season (though Statcast disagreed, grading him at seven outs below average).

2023 Season: Entering the 2023 season, Rosario looked like he could be in line for a notable multi-year deal once he reached free agency. From 2021-22, he’s posted a solid .282/.316/.406 batting line (103 wRC+) with enough defensive aptitude to be valued between 5.2 wins above replacement (via FanGraphs) and 6.2 WAR (Baseball Reference). He stumbled with a .263/.305/.378 slash in 2023.

Rosario recorded a base hit in 87 of 140 games last year (62.1%), with at least two hits in 30 of those contests (21.4%).He went yard in 4.3% of his games last season (six of 140), 1.1% of his trips to the plate.Rosario scored a run in 55 of 140 games a season ago (39.3%), with two or more runs scored in 12 of those contests (8.6%).He picked up an RBI in 42 out of 140 games last season (30.0%), with more than one RBI in 13 of those games (9.3%).In 47.9% of his games last season (67 of 140), Rosario struck out at least once, and in 25 of those games (17.9%) he registered two or more punchouts.

2024 Season: Stats: .280/.306/.380 slash line, .686 OPS, 3 HR, 32 RBI, 13 SB across 103 games Rosario is coming off a 2024 season in which he appeared in 103 games between the Tampa Bay Rays, Los Angeles Dodgers, and Cincinnati Reds, slashing a combined .280/.306/.380 with three HR, 32 RBI, and 13 SB.

Rosario has above-average bat speed and raw power. The ball simply jumps off his bat from his natural whip action through the zone. He is going to hit more home runs than most shortstops.

Scouts say Amed has a 60 hit tool. And he has moderate, 45 grade power. (Spring, 2017)

In 2016, Ahmed shortened up his righthanded stroke. It is not only shorter, but more authoritative, with the bat-to-ball skills he showed last year now translating into harder contact. Better pitch selection also helped him tap into the power in his stronger, maturing body. He still gets pull-happy at times, but when Rosario lets the ball travel a bit, he shows the quick hands and strong wrists and forearms to drive the ball to all parts of the park.

Rosario still is something of a free-swinger who is prone to chasing breaking pitches. But he is adept at hitting behind runners and executing the hit-and-run, and he profiles as a prototype No. 2 hitter. He lines the ball from gap-to-gap with a line-drive oriented approach.

“At first it was a little difficult trying to figure out the strike zone, but over the course of time I was able to make adjustments,” Rosario said. “My biggest improvement was with the strike zone. I shrunk it over the course of time,"

He figures to grow into some power as he fills out his wiry frame, but he primarily is a line-drive hitter who can use all fields. He makes authoritative contact. (Spring, 2017)

He hits effectively to the opposite field. He has good feel for the barrel and his swing generates a lot of leverage. He hits the ball with authority from his pull side to right-center field.

Rosario needs to improve at handling pitches on the inner half of the plate.

And he needs to improve his strike zone discipline. Amed's plus speed helps him leg out some infield hits.

2016 Improvements: Rosario was targeted by many as a prospect who could make a huge leap in 2016, he did just that and then some.

The 20-year-old shortstop began the year in the Florida State League and earned a midseason promotion to Double-A, where he raked even more (.341 average). His combined .324 average placed him fourth in the Mets organization, while he topped the system with 155 hits. The Mets' future at shortstop is coming quickly.

When Amed tracks pitches with two strikes, he seems to lean his weight forward, training his eyes on the ball as long as possible before deciding whether to swing. Mets manager Mickey Callaway likens Rosario's motion to that of Derek Jeter, whose bat speed allowed him to make those choices split seconds later than lesser hitters would.

"I think he's seeing the ball better," Callaway said of Rosario. "He's getting more and more confident that he's going to lay off tough pitches. And the main thing is when he gets his pitch, he doesn't miss it. It's real gratifying," Callaway said. "We spend a ton of time trying to work on the right things with these guys, and I think it's all paying dividends."

"Basically, what I'm doing is putting a lot of trust in myself," Rosario said through an interpreter. "I trust myself a lot more than in the beginning. I think that confidence in myself is everything."  (DiComo - mlb.com - 9/6/18)

Amed has impressive fielding instincts, soft hands, plus range, arm strength, and the natural ability to make the backhand play at shortstop. His actions are both quick and fluid. He grades at 70 for his outstanding defense. And he gets a well-above-average 65 for his great arm.

Rosario is a very reliable shortstop. And starting in 2017, he exhibits polish.

"One thing he learned this year (2017) was how to position himself,” Las Vegas manager Pedro Lopez said, “how to better learn swings and take control over the infield. Last year (2016), some of the errors he made were staying back on balls and relying too much on his arm.”

Rosario is a lean, rangy, athletic shortstop whose hands and arm improved during the 2016 season. (Spring, 2017)

Rosario makes playing the middle infield look easy. He has quick feet plus the range and superb body control to make all the plays. His hands are good, and he can throw the ball from all angles very well.

Rosario is already a plus defender, but he can improve his efficiency by charging the ball more consistently to reduce hurried throws and errors. He slows the game down, makes the routine play look routine, and has the range (70 grade) and arm to make various spectacular plays.

Amed earns comparisons with Tigers shortstop Jose Iglesias as a potential 70-grade defender. He combines a quick first step and premium range with plus arm strength and a knack for making the tough play. (Spring, 2017)

“He’s just got all of the tools,” said Mets first-year big league bench coach Dick Scott, who formerly served as farm director. “His physicality is more pronounced this year than it’s been in the past. What he needs is just to have a really good season, because he’s been playing so much younger than the league he’s been in.”

Amed's speed gives his defensive game plenty of range to go along with his plus hands, footwork, and an arm that is both strong and accurate. In other words, he's a shortstop long-term, not one of these prospects who'll outgrow the position or who has a defensive deficiency that will force a move to second, third or the outfield.  (Mayo - mlb.com - 8/1/17)

Amed has above-average speed, a 60 grade. 

September 14, 2017: Rosario isn't just the No. 1 prospect in baseball, according to MLBPipeline.com. He's also the fastest shortstop in baseball, according to both your eyes and now Statcast. Rosario qualified for the Sprint Speed leaderboards after scoring on a Jose Reyes single, and when he did, he entered as one of baseball's five fastest players. (Mike Petiello-MLB)

May 2020: According to Statcast’s Sprint Speed metric, the 24-year-old’s sprint speed of 29.2 feet per second is tops on the Mets, followed by Brandon Nimmo at 28.5.

In 2019, Rosario was the only NL player to steal at least 19 bases and hit 7 or more triples. But he also led the league in getting caught stealing 10 times.  –Anthony DiComo

July 2016: In Double A, Rosario was on the DL with a strained hamstring.

Aug 3, 2020: Amed left the game due to left quad tightness.

April 29, 2022: Manager Terry Francona said Rosario had been battling some left wrist tightness on and off since the start of Spring Training. When he arrived at the ballpark in Oakland on April 29, it was a little more sore than he had been in the past, so Francona decided to keep Rosario out of the lineup on both April 29 and 30.
