"[Bettis] made a lot of improvements and had a lot on his plate this spring," Rockies manager Walt Weiss said. "And he's been able to go out and perform while he is trying to make adjustments, which is always impressive. He's in a good place. There is some clarity in his role and what he needs to do. It's been a very positive camp for him."
The club also reassigned right-handers Jair Jurrjens and Brett Marshall, left-handers Aaron Laffey, John Lannan and Kraig Sitton along with catcher Audry Perez to Minor League camp. Infielders Omar Quintanilla and Trevor Story and outfielder Roger Bernadina were also reassigned.

"The reality is, at this point in camp, that there are only so many innings to go around and we need to build guys up," Weiss said. "Starters are going longer in the game and there are not as many innings for some other pitchers, so if a guy is not breaking with us, we need to get him down on the Minor League side and get built up, particularly the starting pitching, so they are ready to start a season."
With the moves, the Rockies have 34 players on their 40-man roster and 42 players still in Major League camp. That list also includes seven non-roster players.
