After recently seeing his hitting splits between his DH games and his time in the outfield in his great first season in Boston, it is clear that he hits much better when he is on the field. It is also clear that our outfield is better defended by the trio of Benintendi, Bradley and Betts. And, another factor is that Martinez will far out produce the combination of Moreland and Pearce even if both guys were great teammates in this championship season.
I see him as the classic hitter who needs to move to first base ASAP. Lots of other hitters have made this move (Banks, Yaz, Aaron, Mantle, etc) to keep their bats in the lineup while also helping their team defensively.
With Martinez athletic ability there is no question he could handle first base. He also is a student of the game, so learning and understanding the mental parts of the position will not be a problem either.
If he does not yet have a good first baseman's glove we should all donate a few dimes to get him one. Your thoughts..
