The Rockies announced that they’ve promoted infield prospect Ryan McMahon to the majors. In corresponding moves, the team optioned outfielder Raimel Tapia to Triple-A and designated left-hander Sam Moll for assignment.
Colorado chose to select McMahon’s contract because of first baseman Mark Reynolds’ left hand injury, tweets Nick Groke of the Denver Post. McMahon’s primary position has been third base since the Rockies used a second-round pick on him in 2013, but the 22-year-old has seen plenty of action at first in recent seasons with Nolan Arenado holding down the hot corner in the majors.
The lefty-swinging McMahon is the sport’s 64th-best prospect, according to MLB.com, while Baseball America has him at No. 91. MLB.com’s scouting report credits McMahon’s natural power, but the outlet notes that there are questions as to whether he can handle good pitching.
McMahon has held his own offensively this year at Triple-A Albuquerque, though, with a .375/.409/.625 line in 269 plate appearances, to go with a .250 ISO and 13 home runs. His output has been a whopping 61 percent better than the Pacific Coast League average, per FanGraphs’ wRC+ metric.
Moll, 25, joined the Colorado organization back in 2013 as a third-rounder. He hasn’t yet reached the majors, and has posted so-so Triple-A results in a tough league for pitchers over the past couple years. Moll threw 47 1/3 Triple-A frames of 4.94 ERA ball in 2016 and has amassed the same amount of innings this season. Thus far, he has logged a 4.18 ERA with 7.42 K/9, 3.42 BB/9 and a 50.3 percent ground-ball rate.
