Bohm is hurt too. Shoulder soreness.
I have no issue with our best and highest-OBP hitter getting the most ABs in a game. Whether it's Harper or Schwarber.
Stott has come around lately but he had around a .600 OPS as both a lead-off hitter and in the first half of the season. He's not even guaranteed to play two of these four games (though I suppose with Bohm out too that's harder, if Wilson is also playing OF).
