I would platoon Daniel Vogelbach for now.
Daniel Vogelbach
2019 VS Righties: 126 wRC+, .355 wOBA, .225/.359/.485, OPS .844
2019 VS Lefties: 68 wRC+, .270 wOBA, .161/.288/.315, OPS .602
Rowdy Tellez
2019 VS Righties: 80 wRC+, .293 wOBA, .208/.283/.420, OPS .702
2019 VS Lefties: 114 wRC+, .342 wOBA, .270/.317/.513, OPS .831
(smaller sample)
2020 VS Righties: 87wRC+, .297 wOBA, .200/.268/.460, OPS .728
2020 VS Lefties: 148 wRC+, .388 wOBA, .357/.400/.500, OPS .900
The platoon would be equivalent to a 120 wRC+ bat.
Number are pretty consistent for Rowdy, mashes lefties while below average vs righties.
Vogelbach mashes righties and can't hit lefties.
