"It'll be really good to see Rex," Rockies manager Walt Weiss said. "I'm sure that entire clubhouse will feel the same way. He's throwing the ball well. He's in a good place. It's time to get him back."
Brothers spent the 2013 campaign as an integral part of the Rockies' bullpen, producing a 1.74 ERA and 19 saves in 72 appearances. But control issues plagued him the following year, and Brothers labored through the 2014 season with a 5.59 ERA. His strikeout-to-walk ratio was 1.4, compared to 2.1 in 2013.
An up-and-down Spring Training this year landed Brothers at Triple-A Albuquerque, where he again struggled out of the gates.
