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.
MLB.com’s Mark Bowman confirms a report from Daniel Álvarez Montes of EVTV Miami that the Braves are calling up outfield prospect Ronald Acuña from Triple-A Gwinnett.
The move is obviously much anticipated and expected, as Acuña is considered the top prospect in baseball among those who hadn’t been called up to the majors yet. Acuña has had a slow start with Gwinnett, as he’s batting only .215/.301/.277 in 73 plate appearances. However, he has turned things around somewhat in recent days, batting .379 with a double and a homer since April 17.
Acuña should be in Wednesday’s starting lineup against the Reds and he should be a lineup regular going forward. The expectations are high for Acuña, who signed with the Braves as an international free agent in July 2014.
