show time — at last

Seven years after he was drafted in the first round by Colorado, former Ole Miss star Ryan Rolison has been summoned to the big leagues. The 27-year-old lefty is 3-1 with a 3.72 ERA at Triple-A Albuquerque, working mostly out of the bullpen. Having battled injuries much of his pro career, the 6-foot-2 Rolison has 4.50 career ERA in 95 games covering 308 1/3 innings with 310 strikeouts. The Tennessee native won 16 games in his two years at Ole Miss. The Rockies, off to a 6-33 start, appear fairly desperate for pitching help. They surrendered 21 runs to San Diego on Saturday at Coors Field and have an MLB-worst 5.89 ERA entering play today. … Rolison is the fourth Ole Miss alum to get a big league call this season, following Doug Nikhazy, Gunnar Hoglund and Tim Elko.
