McMahon, 21, is batting .250/.327/.354 with six RBI and one steal through 13 games for Double-A Hartford.
McMahon has fanned a staggering 18 times to begin the season, though perhaps this should not be all that surprising. Even in a stellar year at High-A in 2015, he struck out 153 times in 132 games. A less hitter-friendly environment at this level should be a better indicator of his future trajectory, though McMahon remains one of the better prospects in the Colorado system.
