The Rockies and left-hander Chris Capuano have agreed on a minor league contract, CBS Sports’ Jon Heyman reports (via Twitter). The deal will cost the Rockies only the minimum, as the Red Sox still owe Capuano the approximately $1.18MM remaining on his previous contract after he was released earlier this week. Capuano is represented by Moye Sports Associates.

Capuano will be stretched out as a starting pitcher at Triple-A, Heyman notes, after pitching exclusively out of the bullpen in Boston. The veteran southpaw posted a 4.55 ERA, 8.2 K/9 and 1.93 K/BB rate in 31 2/3 IP this season, and that ERA was largely inflated by a five-run outing on June 23 in what ended up as his final appearance with the Red Sox.

The signing marks both a return to starting and a return to the NL for Capuano, as he spent the first nine years of his career in the senior circuit before signing with Boston last winter. Given the Rockies’ need for starting pitching, it’s basically a no-lose signing on their part to see if Capuano can adapt to the thin Colorado air and eventually provide some innings to the Major League rotation.
