15. J.T. Realmuto (13.2)
J.T. Realmuto‘s time with the Marlins was all too short, but he had a lot of impact during his time with the club. A third round pick in the 2010 MLB Amateur Entry Draft, Realmuto joined the organization as a 6-foot-1, 210 lb. catcher out of Midwest City, OK.
Four seasons later, Realmuto made his big league debut with Miami, going seven-for-29 in 11 games, with nine RBI. 2015 would be Realmuto’s first full major league season. He appeared in 126 games as the Marlins primary catcher, slashing .259/.290/.406 with 10 home runs and 47 RBI, while ranking fifth in the N.L. with seven triples. He only cut down 27 percent of base-stealers, a number he has bested by at least five percent in every season since.
In 2016, Realmuto got better. For the second time in now five consecutive seasons, he posted a career high with 11 home runs. In 137 games, he slashed .303/.343/.428, with career-best figures in batting average and OBP, also stealing 12 bases in 16 tries. Defensively, he earned a .991 fPCT while throwing out 35 percent of runners.
2017 would see Realmuto continue to improve behind the plate. He earned a .994 fPCT and was worth four zone runs above average in 1095 2/3 innings. Offensively, Realmuto played in 141 games and hit .278/.332/.451 with 17 home runs and 65 RBI.
Realmuto spent his last season with the Marlins in 2018, playing in 125 games and clubbing 21 home runs with 74 RBI while slashing .277/.340/.484. He took home his first Silver Slugger Award at catcher for his efforts. Realmuto also threw out 38 percent of stealers while manning the backstop for 952 frames and made his first all-star team.
Although the Marlins still owned exclusive rights to Realmuto through the 2020 campaign, they decided to gain what they could in trade for him. Just prior to Spring Training, they traded him to the Philadelphia Phillies for top pitching prospect Sixto Sanchez, Will Stewart, and major-league starting catcher Jorge Alfaro.
In his first season with the Phillies, Realmuto hit .275/.328/.493, earning another all-star bid, another Silver Slugger, and his first Gold Glove. He threw out an N.L. leading 47 percent of base stealers.
