KANSAS CITY, Mo. — The shortstop who plays across town from Amed Rosario might serve as the best example of a player at his position who figured it out during a season and became a star.
Didi Gregorius was 25 years old, in his third major league season, when the transformation began with the Yankees. Gregorius went from a below-average offensive player in the first half of 2015 with a .619 OPS, to something more special. In the final 74 games of that season, he posted a .762 OPS in a coming-out of sorts. He has been among the game’s best shortstops since.
