Mujica, a 23-year-old right-hander, was most recently with the Rays organization and missed the entire 2019 season after undergoing Tommy John surgery.
When he was most recently on the mound in 2018, Mujica posted a 3.75 ERA in 57 2⁄3 innings at three different levels of the minors. The lion’s share of those innings came at Triple-A Durham, where he had a 2.70 ERA in 36 innings, walking 10 and striking out 34 over seven starts.
In a larger sample, he had a 3.03 ERA and 1.11 WHIP in 25 starts at Double-A Montgomery in 2017, walking 44 and striking out 86 in 154 1⁄3 innings.
According to his 2018 scouting report at DRaysBay, Mujica sports a plus changeup and a low-to-mid 90s fastball that can touch 96 on the radar gun with a developing slider and changeup. That scouting report sounds a bit similar to the report on German Márquez when the Rockies acquired him in 2016, though Mujica was 22 in 2018 and Márquez was 20 in 2016.
Parsons, who the Rockies released to make room for Mujica, had a 7.09 ERA and 1.91 WHIP in 19 1⁄3 innings out of the Rockies bullpen in 2019 after coming over from Atlanta midseason.
