How about the turnaround this season for Rockies third base prospect Ryan McMahon? Last season, McMahon looked rather lost at the dish, hitting just .242 in 133 games for Double-A Hartford. McMahon fanned a staggering 161 times over that span, and also experienced a power outage. He hit just 12 home runs en route to a putrid .399 Slugging Percentage. McMahon has completely reversed course in 2017, though. After slashing .326/.390/.536 through 49 games in a return engagement at Double-A, McMahon was promoted to the hitter-friendly confines of the California League. McMahon has come out of the gates white-hot for Triple-A Albuquerque, hitting an absurd .423/.444/.711 with five home runs and 22 RBI in 22 games at this level. With Nolan Arenado manning the hot corner at the big-league level, and Mark Reynolds enjoying a resurgence at first base, McMahon could end up being valuable trade bait for starting pitching for the surprisingly contending Rockies.
