Castano has three starts under this belt this season totaling 13 1/3 innings with a 4.73 ERA/5.63 FIP. He was slightly more effective last year with a 3.03 ERA/4.81 FIP across 29 2/3 innings. Castano was part of the Marcell Ozuna trade, coming to Florida with Sandy Alcantara, Zac Gallen, and Magneuris Sierra.
Devers, just 21 years old, went 2-for-12 with five strikeouts and a sac fly. He is the Marlins’ 25th-ranked prospect per Fangraphs. Baseball America named him as the Marlins prospect with the best hit tool; they rank his as the Marlins’ No. 10 prospect. Like Castano, he was acquired via trade. He came to Miami from the Yankees as part of the 2017 Giancarlo Stanton swap.
In other news, the Marlins are hopeful that young phenom Sixto Sanchez will have his shoulder healed enough to make his season debut in June, per Jon Heyman of MLB Network (via Twitter). Sanchez has not yet appeared this season after working his way into a role as the Marlins’ No. 3 starter during last season’s playoff run.
