Carlos Estevez

Carlos Estevez is a guy that falls in the same category as Diaz: poor 2020 season and poor 2021 spring showing thus far.

In 2020, he appeared in 26 games and had an ERA of 7.50 and a FIP of 5.69. He did walk slightly more batters than 2019 (2.9 up to 3.4 BB/9) but his strikeout rate was exactly the same (10.1 K/9). His main problem was his home run rate and hit rate. He allowed 2.3 home runs and 12.4 hits per nine innings.

Ideally, each of those numbers would be slashed in half for Estevez to be a key figure in the bullpen.

But in spring training, he has appeared in five games and has a 16.20 ERA. In five innings, he has allowed seven hits, nine runs (all earned), four home runs, three walks, and he has struck out four.

Like Diaz, he will still likely make the bullpen for Opening Day but with some other younger pitchers that have pitched better in spring training thus far, Estevez may, perhaps, find himself looking for a new home in the near future.
