The Astros acquired left-hander Travis Blackley from the Athletics on Thursday in exchange for minor league outfielder Jake Goebbert, but he hurt his shoulder before he could appear in a game with his new club and will head to the disabled list as a result.
According to Zach Meisel of MLB.com, Blackley strained his shoulder during a bullpen session yesterday. It’s not known how long he’ll be sidelined, but the Astros were planning to use him as a long reliever.
The Astros have recalled left-hander Dallas Keuchel to replace Blackley on the active roster. The 25-year-old posted a 5.26 ERA and 38/39 K/BB ratio over 85 1/3 innings in 16 starts with the club last season.
