Ryan McMahon has seen time at first in the past but the Rockies aren’t likely to use him there.
Despite playing the majority of his games at first base in 2018 and 31 games there in the last two seasons, you likely won’t see McMahon at first base to start the season unless there’s an injury or the Rockies are out of bench players.
"“You know, we’ve talked about (playing McMahon at first base) in a pinch,” said Black. “I mean, it could happen further down the road if Brendan (Rodgers) comes back and is on our roster, or if somebody else emerges at second base–and we like Josh (at third base)–but I would think that Josh always has the capability to go on first base, too. We saw that last year, as well. And Josh played really well at first base offensively (and defensively). So I can’t speak enough to the versatility but I wouldn’t, at this point, want to move Mac around to three infield positions on a regular basis.”"
And McMahon has said numerous times in recent years that he doesn’t really care where he plays, as long as he is on the field and he reiterated that on Monday when he spoke with the media.
"“That’s baseball,” said McMahon. “Anything can happen on any day so I’ve stayed ready–me personally. Hopefully, we get Brendan (Rodgers) back really quick but I’ll do whatever (Bud Black) asks me to do.”"
