The Rockies massaged their roster without losing any pitchers. Relievers Chris Volstad and Logan Kensing were outrighted off the 40-man roster Monday after clearing waivers, and accepted assignments in Triple-A Colorado Springs. Volstad could resume starting in Triple-A. He was called up recently to help an exhausted bullpen, but struggled. Kensing replaced Volstad, but the Rockies chose to carry five outfielders rather than 13 pitchers. As a result, he was designated for assignment when outfield prospect Corey Dickerson was promoted on Friday.
