Rodriguez is a lean lefthander who throws strikes with his lively sinking and tailing 91-94 mph two-seam SINKER that keeps hitters off-balance. He also has a 92-97 mph four-seam FASTBALL. His 84-87 mph tight, biting 84-87 mph SLIDER with excellent tilt is a 50, that flashes 60 grade, and works when he throws it to the back foot of righthanded hitter. He can bury his nasty, swing-and-miss 85-88 mph CHANGEUP (a clear 60 on the 20-80 scout scale), which he throws with the same arm speed as his heater.
When Eduardo is at his best, he works down in the zone with his fastball. It has arm-side run away from the barrel of a righthanded hitters bat. And the changeup dives away to his arm side. He attacks lefties with that change and it's effective.
Rodriguez will throw the changeup in any count with similar arm speed to his fastball. He induces ground balls and swings and misses with both velocity and pitch location. In short, he knows how to pitch. And he'll get better with more experience against quality hitters.

2020 Season Pitch Usage: Did not pitch.
The ball comes out of his hand well. When he was on the Orioles, they helped Rodriguez overhaul his delivery and get more on line toward the plate without robbing him of deception.
Eduardo can become inconsistent with his arm slot and sometimes leaves his heater up in the zone. Those are just minor dings, however, and scouts project him as a mid-rotation starter at least, if not a No. 2 as he makes improvements.
He now has an uncomplicated delivery and smooth mechanics. He has a very loose and free release, with the ball leaving his hand with ease. But he has a tendency to get quick with his delivery and lose the strike zone.
In 2013, Rodriguez's improvement could be traced to his situational pitching that season, according to Bowie BaySox manager Ryan Minor.
"[Young pitchers] don't understand how valuable it is to prepare yourself in between, not only physically but mentally, to understand the teams you're facing and to read hitters swings and things like that," Ryan Minor said. "For Eddie, I've seen a big difference from last year to this year (2013) between his starts."
Eduardo credited Portland pitching coach Bob Kipper with helping him to use his changeup and slider to both sides of the plate against both righties and lefties for his breakthrough season in 2014.
Eduardo shows amazing poise and self-confidence on the mound. He has the type of mound demeanor that can carry him through the best of times and some difficult hiccups, should they arise. He doesn't get rattled.
Rodriguez doesn't pitch inside much at all. On the contrary, he mostly stays on the outside corner on all hitter. (October 2013)
Eventually, Eduardo will find the inside of the plate and throw the ball under the hands of the lefty hitters. That will make a difference. (Spring 2014)
- Rodriguez relies upon a moving fastball as the bread and butter of his arsenal. It's a pitch that is difficult to catch up with and one with which he has great success. Rodriguez uses it to set up an improving changeup and a steady slider. Both of those off-speed pitches are true weapons, and they tend to sit at 8-10 mph less than his fastball without much differential.
Rodriguez's changeup against lefthanded hitters is a difference maker in his overall game plan. Once he has the hitter sitting on the blazing speed, the 10 mph difference and the change in the location baffles hitters.
His command and control are well advanced beyond his age. Rodriguez knows how he wants to sequence each hitter, and he comes right after it with good follow through and extension. He makes pitching look easy.
Rodriguez scuffled a bit with his command and control prior to being traded to the Red Sox. However, his delivery is smoother, his landing point is direct and he repeats his good mechanics pitch after pitch. That has all come with improved confidence. Where Rodriguez once may have been seen as a thrower, he is now more a true pitcher. (Pleskoff - mlb.com - 7/20/15)
As of July 20, 2015: In his 535 innings of Minor League pitching, Rodriguez had yielded only 22 home runs. The highest total he surrendered in one year was 9, in 2013. In other words, Rodriguez is the consummate groundball pitcher.
2015 Season: Rodriguez's success left everyone in the organization beaming about his future. E-Rod not only has the stuff to pitch in the Major Leagues, but also the poise. The lefty finished with a 10-6 record and a 3.85 ERA in 21 starts. His last seven starts represented his best run of the season, as he went 4-1 with a 2.08 ERA.
In 2017, Eduardo moved to the first base side of the rubber to start the season.
Rodriguez also changed his arm angle for a number of reasons: He was tipping his pitches, not taking the ball out of his glove the same way—instead, tipping off his fastball because he took it out of his glove differently that his curve.
Eduardo has learned a lot from both David Price and Chris Sale, fellow lefthanders on the Red Sox staff.
Feb 19, 2019: Eduardo threw a pitch in the bullpen that was so on point, it prompted ace Chris Sale to laugh. The legendary Pedro Martinez knows ace-speak, so he knew exactly what Sale meant by the laugh.
"That's ridiculous. Just ridiculous," Martinez said, when asked what Sale thought of that particular pitch. While Martinez stood next to Rodriguez during the side session, Sale stood behind him for a close-up look. Two of the best pitchers the Red Sox have ever had are clearly invested in Rodriguez, and they hold the belief he will be something special.
A few minutes later, Rodriguez took his filthy arsenal out to Field 5 for batting practice, and Sale gleefully tagged along. "Eddie, you throwing live today?" Sale asked. "I'm riding shotgun."
Less than two months from his 26th birthday and entering his fifth season, 2019 sure looks like leap year for Rodriguez.And nobody believes Rodriguez is ready to take that leap more than Martinez, who as a special instructor for the Red Sox has essentially been joined at the hip with his protege for the last several Spring Trainings.
When batting practice session ended, Martinez clapped into his glove and shouted. "That was one of the most impressive BPs that you could see," said Martinez. "No hesitation, no stopping. It was beautiful to watch." Overall, what makes Martinez so excited about where Rodriguez is at this spring?
"I see for the first time he is demanding more out of every pitch," Martinez said. "He's asking for more and more. He's making good quality pitches, but he wants to improve them." It helps that Rodriguez is also, by the accounts of many and obvious to anyone who observes him, in the best physical shape he's ever been in. Last season, Rodriguez went 13-5 with a 3.82 ERA.
"Eddie, I think, physically is more mature now," Martinez said. "He understands his body better. He's understanding where he needs to improve. He's not really worried about his position physically, because this is his first time in Spring Training the last few years that he comes over and there's no worries. He can just pitch."
The possibilities seem endless, which is why Rodriguez draws such big crowds when he throws batting practice on a practice field. "The work he put in the offseason is paying off. He's repeating his delivery," said Red Sox manager Alex Cora. "You ask any of those guys, everybody was watching. He's kind of like the favorite pitcher of the whole camp. When he throws live BPs, everybody is out there watching."
"It's just a matter of him putting a whole season [together], and we do feel it's going to happen this year. Looking forward, he'll be great for us. He's going to be good." Rodriguez is in a rotation surrounded by accomplished veterans, and while he appreciates his role as the little brother, he's ready to be on an even playing field.
"That's the way they look at me and I love it. That way they just teach me all the time. You've got Cy Youngs from these guys here. I love the way they treat me. Like a little brother," Rodriguez said. "But I want to get to that point. I want to get to the point where I can be available to win a Cy Young one day. But like I said, I just want to be healthy and help the team to win games." (I Browne - MLB.com - Feb 19, 2019)
2019 Improvements: After a stellar outing from Rodriguez and a relatively dominating performance from the Red Sox overall in game three against the Tigers, the starting lefty let us all in on a little secret. That breaking ball that he was throwing so effectively last night? He didn’t learn that from pitching coach Dana LeVangie. He wasn’t given this grip by one of the greats, Pedro Martinez. Instead, it was Dustin Pedroia who taught him how to throw his newest breaking pitch.
After being asked last night, Rodriguez had this to say about it, via Michael Silverman of the Boston Herald.
“It’s funny because four days ago, I was talking with Pedey in the dugout and he told me, 'Hey, do you want to throw a really good breaking ball?' I was like, 'Yeah, bro, I’ve been battling to throw a breaking ball since I got in the big leagues.'"
Rodriguez then explained that Dustin Pedroia showed him the grip he had used to use during his days as a pitcher while in school. (Nick Quaglia - April 25, 2019)
2019 Season: In his breakout 2019 season -- the last time he pitched -- Rodriguez went 19-6 with a 3.81 ERA and 213 strikeouts in 203 1/3 innings, finishing sixth in American League Cy Young Award voting.
- 2020 Season: Instead of returning from the pandemic shutdown in July with the rest of baseball, Rodriguez was stuck in bed, sick with the coronavirus. When he recovered from that illness, doctors diagnosed him with myocarditis — a complication of COVID-19 that affects the heart and wound up costing him the entire 2020 season.
- As of the start of the 2021 season, Eduardo had a career record of 51-31 with a 4.03 ERA, having allowed 88 home runs and 659 hits in 699 innings.
