SCOTTSDALE, Ariz. -- Right-hander Tommy Kahnle has been optioned by the Colorado Rockies to Minor League camp, the club announced Wednesday after defeating the Giants, 5-2, at Salt River Fields.
A pickup from the Yankees in the 2013 Rule 5 Draft, Kahnle, 25, remained with the Rockies all last season and worked 54 games in relief, compiling a 2-1 record, 4.19 ERA and 1.19 WHIP.
"With Tommy, we've all seen the talent," Rockies manager Walt Weiss said. "He had a very good year for us as a Rule 5 guy last year. It's not the only reason he stayed up with us. He stayed up because he was very good. We're just working on some consistency with Tommy, that's all."
Kahnle essentially pitched well this spring, allowing only one run on three hits in 4 1/3 innings over five relief appearances. His demotion could open a position for veteran reliever Rafael Betancourt, who is in camp trying to make a comeback as a non-roster player on a Minor League contract.
Kahnle's demotion leaves 40 players in Colorado's big league camp, seven of them non-roster invitees.
