At this point the Braves leaders in xwOBA (min 20 PAs):
1 Murphy, Sean .480
2 Acuña Jr., Ronald .431
3 Olson, Matt .390
4 Hilliard, Sam .358
5 Arcia, Orlando .351
6 Pillar, Kevin .350
7 Rosario, Eddie .345
8 d'Arnaud, Travis .339
9 Albies, Ozzie .334
10 Riley, Austin .332
11 Ozuna, Marcell .322
12 Grissom, Vaughn .319
13 Harris II, Michael .304
Assuming Ozuna is just always going to be an xwOBA underperformer (the "why" isn't as important as the fact itself), it looks like some form of Hilliard/Pillar platoon in LF is the play once everyone is healthy.
Some combination of Murphy/Rosario in the DH spot (let Murphy DH vs LHP so TDA can catch and Rosario can sit).
At some point Harris either needs to improve vs LHP, or some sort of platoon will be required late in the season and into the playoffs. That guy may be White.
