SCOTTSDALE, Ariz. -- Patrick Corbin has pitched extremely well this spring, and it probably won't be enough to make Arizona's opening-day roster.
Corbin tossed five hitless innings to lift the Diamondbacks to a 7-3 victory over the Colorado Rockies on Tuesday.
The left-hander struck out three and walked two while lowering his spring ERA to 0.57.
"The first two innings I was a little rusty and was trying to find the strike zone," Corbin said. "After that it went away and I was able to throw all my pitches."
"No matter where I start this year, I am glad I got the chance to show them what I have, "Corbin said. Hopefully I will get a shot."
Corbin also impressed at the plate, going 2 for 2 with a triple and an RBI. Geraldo Parra added two hits for Arizona.
Jeremy Guthrie, slated to start on opening day for Colorado, gave up six runs, four earned, and 10 hits in six innings. He struck out two and walked one.
"Every outing is a chance to get more prepared for the season," said Guthrie, who was acquired in a trade with Baltimore on Feb. 6. "As long as you got out there, do your work and have a focus, then they all can be productive. You like the outcome to be as good as they can be every time but ultimately you have to work on things and make sure you are ready."
