Five-tool players are exceedingly rare in baseball today, especially ones who play a premium position. In J.T. Realmuto, the Philadelphia Phillies are acquiring a five-tool catcher who may be on the verge of superstardom, now that Citizens Bank Park is home.
Realmuto has been suppressed by Marlins Park, which has rated among the five least-friendly ballparks for hitters in each of the past three seasons. The gap between his OPS there and all other ballparks (.205 points) is equivalent to the difference between Mookie Betts' and John Jay's OPS during that time.
