Carlos Santana
Some players, for whatever reason, spend their entire career flying under the radar. Carlos Santana falls into that bracket.
In the shadow of Francisco Lindor and Jose Ramirez in Cleveland and bemoaned in Philadelphia, Santana’s status as one of the game’s premier first basemen is often forgotten about. He got back to his best in 2019 with a 135 wRC+, good for joint-fourth among qualifying first basemen.
Santana had the best power year of his career in 2019. If that proves to be a breakthrough, he could age very gracefully into his mid-thirties.
The combination of low strikeouts (108 last year) and a lot of walks (also 108 in 2019) is a great one, particularly if he can retain that pop.
