Point of order: a walk ISN'T as good as a hit.
A single is worth approximately 1.3 times as much as a walk by modern analytics. And of course doubles, triples and HRs are also hits and worth way more than a walk.
Walks are great, and OBP is important, but viewing it in a vacuum misses important information. OBP primarily built on batting average is "worth" more than OBP built on walks. Hitting also translates better against good pitching (the kind you're likely to meet in the postseason) than walking. Good pitching limits walks, almost by definition.
As for Gallo.... He'll play, there's no need for me to "give him a chance."
But...yuck.
