Geraldo Perdomo has flipped from solid defender to a two-way catalyst for the Diamondbacks, driving a late-season charge with a breakout that ranks among the NL’s best. Through 19 homers, 26 steals and a 138 wRC+, his 6.6 fWAR sits behind only Ohtani and Turner in the NL. His improved contact and xwOBA coincide with Arizona’s dash toward a Wild Card, underscoring a breakout that reshapes his fantasy value and the MVP discussion while reinforcing his Gold Glove-caliber defense.
