The Rockies activated left-hander Chris Rusin from the disabled list and optioned right-hander Antonio Senzatela to Triple-A Albuquerque on Friday in advance of their three-game series against the Mets in New York.
With the addition of Rusin, Colorado will have four lefties in its bullpen against the Mets, whose roster has four left-handed hitters and three switch-hitters. Rusin has a 4.97 ERA with 11 strikeouts through 12 2/3 innings in eight big league games this season. The 23-year-old southpaw walked one and struck out four in 1 2/3 innings in his last relief big league appearance against the Cubs on April 22.
