Robles' contract was selected by the Red Sox on Thursday, Rob Bradford of WEEI.com reports.
Robles missed most of camp due to visa issues but will nonetheless win a spot on the Opening Day roster. He could see time in low-leverage spots to begin the year as he finishes his spring build-up, but his 3.60 ERA and 30.3 percent strikeout rate in 25 innings down the stretch for the Red Sox last season earned him four saves, and he could potentially add to that total this year once he's up to full speed.
