With his dominant outing against the Giants, Corbin ("Corby" for Players Weekend) has allowed just one run over his previous 30 1/3 innings, good for an ERA of 0.30 over the span of four starts. His dominant August spilled over into the Arizona's series with the Giants and helped push the D-backs to their first series sweep since June.
"Team effort today, and it was set up by Patrick Corbin, who worked into the eighth inning," Arizona manager Torey Lovullo said. "It was still a very tight ballgame and he was executing pitches all the way through until the final batter. I thought the seven-plus innings that he gave us were very consistent with what he's been doing prior to that."
The most trouble Corbin encountered Sunday came in the first inning, when Kelby Tomlinson roped a one-out double, and then Hunter Pence drew a walk before Corbin got Buster Posey to ground into a 6-4-3 double play.
Corbin's ERA for the 2017 season sat at 4.89 at the start of July, but has been on a steady decline since then and is now 3.91.
The 2013 All-Star believes that one of the main reasons for his rapid return to success over the past few months has been his willingness to attack hitters early in counts.
"Strike one is something that I did really well a couple of years ago," Corbin said. "Just got ahead of guys and kept them off balance. When I'm able to do that I can throw all my pitches. It's something that I try to do, and it just seems right now it's going well. Just locating my fastball."
Of the 96 pitches Corbin threw on Sunday, 22 resulted in called strikes, and 12 of those called strikes came on his slider.
"Maybe mechanically I wasn't there," Corbin said. "Wasn't able to locate as well as I'm doing now. Not sure if there's a reason for that. Maybe just repeating my delivery and focusing on getting ahead of guys."
Corbin also tallied nine swinging strikes on his slider Sunday, which has been a common theme for him this year. According to Statcast™, Corbin has drawn 157 swings-and-misses on his slider this season, good for the third-most whiffs in the Majors on that pitch.
"There's complete execution and the delivery is the same on every pitch," Lovullo said. "The arm speed is the same He's throwing all his pitches with extreme confidence and that's why you're getting a lot of the swing-and-miss. All pitchers work for that little common denominator where your delivery doesn't change whatsoever, and there's deception with that; pitches coming out of it go different ways and I think Patrick's locked in right now in that area."
