Scouting Report
While he’s had struggles in parts of two big-league seasons, Castro remains a physically projectable 21-year-old with an upper-90s fastball and wipeout slider. He began 2016 with eight strong innings before he was shelved with shoulder inflammation in late April. He required a second DL stint in August.
When healthy, Castro sits 96-99 and touches 100 with a plus-flashing slider in the 82-85 mph range. His fastball plays up against right-handed hitters because of Castro’s arm slot and the extension in his delivery. Castro doesn’t routinely throw a changeup, nor does he consistently command his fastball/slider combination but he’s a lanky 6-foot-5 and just 21 years old, so control issues shouldn’t be all that shocking. He could develop average command in time.
Considering the cocktail of command issues, injury issues and lack of a third pitch, it might be too ambitious to attempt to rebuild Castro as a starter. There’s late-inning stuff here if he can get healthy. Castro was acquired from Toronto as part of the Troy Tulowitzki trade.
