Rockies pitcher Jordan Lyles allowed five unearned runs on two hits and two walks in four innings in Tuesday's 7-6 win over the White Sox.

Lyles ran into trouble in his fourth and final inning but escaping the outing without having any runs charged to his ERA, which has falled to 0.60 through 15 spring innings. He threw 55 pitches after coming into the start hoping to raise his pitch count to 70, the Denver Post reports.

"I feel good," Lyles said. "I think where I’m at now is strides ahead of where I was last year at this time. I can say that with confidence. A lot of that has to do with my changeup, and I was working on my curveball today. I threw some good ones and some bad ones."

Lyles is locked into a rotation spot to start the season.
