Well he's technically been to the plate 56 times.
Obviously walks and sacrifices don't count toward batting average but do for OBP. I'm not sure how many RBI he's gotten from guys being walked in, but either way it's still impressive. The guy has 15 walks on the season, which is 10 more than the next closest on the team. I know we've only played 16 games, but an OBP over .600 with that many at bats is insane. He's managed to outshine Adam Frazier at the plate, which is pretty damn hard to do.
