According to Brian McTaggart of MLB.com, the Astros announced this morning that left-hander Sergio Escalona has a torn ulnar collateral ligament in his elbow and will undergo season-ending Tommy John surgery next week.
Escalona, who was acquired from the Phillies last January, posted a 2.93 ERA and 25/11 K/BB ratio over 27 2/3 innings out of Houston’s bullpen last season. The 27-year-old held left-handed batters to a .188/.278/.313 batting line and a .590 OPS.
With Escalona sidelined, Wesley Wright and Fernando Abad will likely compete for the team’s left-handed specialist job. Astros general manager Jeff Luhnow hasn’t dismissed the possibility of using non-roster invitee Zach Duke out of the bullpen if he doesn’t win a spot in the starting rotation.
