Minor MLB Transactions: 4/15/17

Today’s minor moves from throughout the game:

• The Rockies have signed left-hander Steve Ascher to a minor league contract. The 23-year-old was previously with the Rays, who selected him in the 17th round of the 2014 draft. Ascher has spent most of his professional career at the Single-A level, though he did ascend to Double-A last season. In 46 innings, Ascher logged a 4.30 ERA, 7.04 K/9 and 3.52 BB/9.
• The Athletics have announced that they’ve selected the contract of outfielder Jaff Decker. To clear roster space, they’ve optioned outfielder Mark Canha to Triple-A Nashville and placed outfielder Jake Smolinski (shoulder) on the 60-day DL. Canha was off to a poor .105/.150/.158 start in 2017 after missing much of 2016 to a hip injury, and Decker (who has had prior cups of coffee with the Padres, Pirates and Rays) was batting .387/.472/.452 for Nashville.
• Astros righty Lupe Chavez has retired, as Jake Kaplan of the Houston Chronicle notes. The Astros acquired the 19-year-old Chavez last August when they traded Scott Feldman to Toronto. Chavez had never pitched above the short-season leagues but had generally been successful, with a 2.19 ERA, 8.4 K/9 and 2.5 BB/9 over 107 career innings. The reason for his somewhat surprising decision to retire isn’t known.
