When Davis was called up last season, he couldn't hit for his first 7 games, but then he went on a good tear and ended up posting an above-league-average wRC+ over his limited plate appearances (just short of 70 I think). So if last season was any guide, he should be ready to catch fire now. We saw in spring training that he really does know how to hit.
Hinch needs to have another talk with Springer about how he's not sitting him and he should just go have fun and play.
