The Brewers aren't the only team to hit significantly better against RHP compared to LHP. Most of the teams that do so are pretty bad (CIN is the only one in our division), However, there are three very good teams that share that inclination with the Brewers: LA Dodgers, Houston, and NY Mets. Two of them might be opponents in the National League playoffs, and Houston is a legitimate contender to get to the World Series.
We have an excellent internal opportunity to improve the LHP on the team with Ethan Small. Of course you don't move Burnes out of his normal rotation spot (and Lauer is a lefty), but our other starters have been inconsistent this year. Any chance we move Small onto the roster to get a couple of starts vs teams that do badly against LHP*, or at the very least call him up early enough to be playoff eligible?
* Brewers play against a few teams that do badly against LHH June 10-19, and have home and away series against LAD in middle-late August.
