Corbin (6-8, 4.77 ERA) will make his 22nd appearance and 17th start on Tuesday against the Rockies, looking to cap off his impressive rookie campaign with a win against a club he struggled against less than two weeks ago.
He gave up five runs on nine hits and was pulled after just three innings the last time he faced the Rockies in Colorado on Sept. 22. He followed that up with another three-inning showing against the Giants last Thursday, giving up six runs on seven hits.
In total, he gave up 11 runs, 16 hits and four homers in six innings of work, after previously holding the Giants to two runs on two hits over eight innings earlier in September.
"I just have to learn to minimize damage," Corbin said. "I've just got to make better pitches. I've just got to go out there and make better pitches on those counts instead of just throwing the fastball in there and letting them hit it."
He'll toe the rubber against Rockies starter Jhoulys Chacin, who hasn't lost in four consecutive outings.
Chacin (3-5, 4.78 ERA) will be making his 14th start of the season and just his ninth start since being activated in late August. He earned a win in his most recent outing, giving up three runs on seven hits over five innings against the Cubs.
The 85 pitches he threw in Chicago marked his highest pitch count since his return from injury.
The Rockies escaped with a 7-5 win on Monday in a 13-inning duel, marking their longest game of the season They will look to capture their 14th series victory with a win on Tuesday.
Rockies: Ortega available after injuring leg
Rafael Ortega's Major League debut didn't end quite as he had hoped. The left-handed-hitting outfielder was hit in the leg in the ninth inning on Sunday and was attended to on the field.
He stayed in the game, but had x-rays on his leg on Monday, which came back negative.
Ortega, who was pulled out of the Arizona instructional program to join an injury-depleted Rockies roster, was not in the starting lineup for the Rockies on Monday, but did make a pinch-hit appearance in the sixth inning.
Ortega would likely have not started in any case against D-backs lefty Wade Miley.
Troy Tulowitzki, who continues to test his surgically repaired left groin, hit a home run in an Arizona Instructional League game on Monday, but manager Jim Tracy couldn't say whether his shortstop could play in the final two regular-season games of the year.
Tulowitzki last played May 30 before going under the knife on June 23, and has yet to feel confident about a return, despite several Triple-A and Double-A rehab stints.
"All I wanted to hear was he did not have any type of discomfort or pain in trying to make the play," Tracy said of Tulowitzki's rehab games. "That's what you look forward to hearing after having your guy being out as long as he's been out. It has more to do with mental peace of mind more than anything physically."
D-backs: Goldschmidt, Johnson return to lineup
First baseman Paul Goldschmidt and third baseman Chris Johnson both returned to the lineup Monday for Arizona, giving the D-backs a little boost to end the season.
Goldschmidt, who missed the weekend series against the Cubs after feeling stiffness in his back Friday, went 2-for-6 with a solo home run in the bottom of the ninth to send the game into extra innings.
"It tightened up on me that day during [batting practice] and it was hurting pretty bad," Goldschmidt said. "But it's gotten better every day and it feels good now. The trainers did a lot of work on it."
Johnson, who suffered a deep bruise after being hit with a pitch on his left hand, saw his first action since Sept. 23, going 0-for-5 with a sacrifice fly.
The D-backs handed out organization awards Monday, honoring right-hander Trevor Bauer and outfielder Adam Eaton for their outstanding Minor League seasons. Bauer earned Pitcher of the Year, while Eaton was named Player of the Year.
Bauer went 12-2 with a 2.42 ERA in 22 Minor League starts, and Eaton led all Arizona Minor Leaguers in average, hits, doubles and runs scored.
Both players made stints in the big leagues at some point this season.
The Rockies are seeking their first series win at Chase Field since 2009.
Wade Miley made his final start of his rookie season Monday, penciling his name into the record books. Miley set club records with 29 starts, 16 wins and 194 2/3 innings pitched.
