Garcia at third would be about equivalent to starting Luke Voit at 3rd.
It would make more sense to move Garcia to DH, Meneses to RF and Thomas to LF moving Call and Garrett to the bench. That frees up 2nd for Baker.
That gives you a lineup of:
1. Baker
2. Thomas
3. Meneses
4. Ruiz
5. Garcia
6. Smith
7. Candalario (until Kieboom is ready)
8. Abrams
9. Robles
That's a nice improvement IMHO.
