The Marlins have sent left-hander Daniel Castano outright to Triple-A Jacksonville, according to the transactions log at MLB.com. He was unclaimed on waivers after being designated for assignment on Tuesday.
Castano has made two appearances for Miami on the year, allowing eight runs over three innings. The 28-year-old southpaw has pitched for the Fish in four straight seasons, topping out at 35 2/3 frames a year ago. He has a career 4.47 ERA over 24 appearances, 17 of which have been starts. While his 12.4% strikeout rate is well below-average, he has generally thrown strikes and kept the ball on the ground when given opportunities as a depth starter.
This is the third time this year in which the Fish have sent Castano through waivers. He accepted the previous stint and has started eight of 16 contests in a swing capacity with Jacksonville. Over 57 2/3 innings there, he owns a 4.06 ERA with average strikeout and walk marks (22.4% and 8.9%, respectively). The Baylor product has allowed 4.02 earned runs per nine through 170 career innings at the top minor league level.
As a player with multiple career outrights, Castano has the ability to elect free agency. It isn’t clear whether he’ll do so. He’d reach minor league free agency at the start of the offseason unless the Marlins add him back to the 40-man roster regardless, so he could choose to stick in Jacksonville as multi-inning depth for the season’s final couple weeks.
