Yes.
How much of Marwin's offensice track record was helped out by garbage can thumping? Since leaving Houston, his OPS+ is 87. Munoz' is 98.
So yes, Munoz could leap him this year, if you don't think he already has.
Now as a switch hitter, Gonzalez does provide a LHH bat for the bench, which some talking heads have called a need for this team. In that regard, as little faith as I have in Marwin, I will concede hit hits left-handed better than Munoz probably would...
