The Yankees sent cash considerations to Colorado in exchange for the 35-year-old lefthander.
Capuano began the season with the Red Sox. He made 28 appearances, all in relief, accumulating a 4.55 ERA. He was released by the Red Sox on July 1 and signed a minor league deal with the Rockies three days later. The Yankees will be Capuano's sixth major league team.
Capuano made four minor-league starts for Colorado—three in Triple A, one in Double A—and had an ERA of 2.79.
The Yankees sit three games behind the Baltimore Orioles in the AL East, and a half game back of Seattle for the final Wild Card spot.
