wxOBA vs RHP (min 50 PAs):
Acuña Jr., Ronald .440
Murphy, Sean .411
Olson, Matt .410
Ozuna, Marcell .357
Riley, Austin .333
Albies, Ozzie .286
Rosario, Eddie .284
Hilliard, Sam .278
Harris II, Michael .278
Arcia, Orlando .271
That's 5 legit bats plus 3 guys (Ozzie, Harris, Arcia) who aren't going anywhere vs RHP this year. And yes, discussions about Ozzie batting exclusively RHed need to happen.
wxOBA vs LHP (min 30 PAs to get Arcia in there):
Arcia, Orlando .552
Murphy, Sean .496
Acuña Jr., Ronald .492
Albies, Ozzie .448
Riley, Austin .371
Pillar, Kevin .367
Ozuna, Marcell .363
Harris II, Michael .346
Olson, Matt .301
Grissom, Vaughn .288
We know the team destroys LHP, and this is why. The need for a RHH simply isn't there, but it would be nice if TDA or Murphy could give Olson 1-2 days off a month. In the case of Albies, there's no way in the world the RHH who posts a .448 xwOBA vs LHP wouldn't post an xwOBA better than .286 vs RHP if he batted exclusively RHed.

So given that Harris, Albies and Arcia probably are never going to sit vs RHP, the main need for this team on the offensive side is a LFer who can post a .320+ xwOBA vs RHP to replace Rosario. That guy can be a RHH, but he will probably be a LHH with platoon splits. If the answer ends up being more PAs for TDA at DH and Ozuna in LF...I guess we cringe and watch it happen.
