I think so, yes. First off, in 55 plate appearances, Adrian Gonzalez is batting .239 with a .345 OBP and .391 slugging percentage, most of which have come against right-handed hitters. He still has a good eye, and he knows his strike zone, but it has been more than a year since he's had any sort of punch to his bat.
Meanwhile, though he has played in 18 games, Wilmer Flores has started just seven, but all of them have been at first base. In that time, he's hitting .263 with four extra base hits, five RBI and is on pace (mostly as a bench player) to be a 1.
