Just one inning shy of reaching a 200-inning workload this year, Patrick Corbin was close to being shut down by the D-backs. But the left-hander is slated to start Sunday versus Colorado and Arizona still believes he has plenty of gas left for his last two outings.
"He's excited to have his last two starts, he wants to have his two starts," manager Kirk Gibson said. "He's not thinking, 'You know I can just tell him I'm dragging and get out of here and chill out.' No, he wants it."
Corbin is coming off the shortest start of his career in which he allowed six runs on seven hits over just two-plus innings versus the Dodgers on Tuesday. He is 3-0 with a 1.52 ERA against the Rockies this season.
Colorado will counter with Juan Nicasio. The right-hander showed improvement since a brief stint with Triple-A Colorado Springs, but has still struggled to find his consistency this season.
Since he was recalled July 12, he is 4-4 with a 4.59 ERA. He was knocked around against the Cardinals last week for eight runs in just 2 2/3 innings, his shortest home start of the year.
"We're definitely looking for more consistency," Weiss said after the start. "He's been a lot better since he got back to us from his trip down to the Springs. I wonder how much of it is time missed from last year. He's grinding to the finish line here. He's been better at staying away from those big innings, but he struggled with that tonight."
D-Backs: Goldschmidt hoping to play in all remaining games
Paul Goldschmidt has played in 152 of the D-backs' 154 games this season. And if it's up to Goldschmidt, he'll stretch that number to 160, as the D-backs head into their final eight contests of 2013.
"I think everyone wants to play as much as they can," he said. "We get paid to play and it's fun. You get to play baseball. We're all very fortunate to get an opportunity to play, it's what we all dream of growing up. It think if you ask every single guy in here, they want to play every game."
• Arizona intends to remain in its current rotation through the end of the season. Corbin, Brandon McCarthy and Wade Miley will each make two more starts, while Friday and Saturday's starters, Randall Delgado and Trevor Cahill, will return to the mound one more time.
"As of right now, that's the way we're going to go," manager Kirk Gibson said. "We just kind of watch how everybody is throwing. There's no red flags on anybody right now."
Rockies: Backup outfielders stepping up
The Rockies entire starting outfield -- Dexter Fowler, Carlos Gonzalez and Michael Cuddyer -- is currently out with injuries. But Colorado hasn't experienced much of a drop-off thanks to the performances of the interim trio of Corey Dickenson, Charlie Blackmon and Charlie Culberson.
Blackmon has bounced around the lineup, but is settling in as the Rockies' leadoff hitter, getting his third start (sixth in 10 games) batting first Saturday.
"I think the bottom line is he's just stringing together a lot of good at-bats," manager Walt Weiss said. "Some of them against tough left-handed pitchers. He's got a nice plan at the plate and he's executing it. So Charlie's been a real bright spot for our club."
• Arizona clinched the season series last week and takes a 11-7 lead into Sunday's finale.
• D-backs catcher Wil Nieves, who played in Colorado for part of the 2012 season, shared some thoughts on the challenges his pitchers will face at the hitter-friendly Coors Field.
"The breaking ball here doesn't do the same thing. It's kind of tough, especially the first time to go out there, they have to find that release point."
