The Cardinals' No. 16 prospect took a no-hitter into the sixth and ended up allowing a pair of hits over seven innings en route to his first Triple-A win as Memphis blanked Omaha, 5-0.
Gorgen (1-2) had his no-hit bid end when Anthony Seratelli tripled with two outs in the sixth. He escaped trouble by retiring Max Ramirez on a grounder to second base, then pitched around a single in the seventh, getting Rey Navarro to bounce into a double play on his 77th and final pitch of the night.
"For me, it was just a matter of mixing up everything," the 25-year-old right-hander said. "My sinker was working pretty good, I was mixing up my changeups, and it was about going in and trying to keep them off-balance and go at them a different way.
"They're in first place, they have a power lineup. It was just a matter of giving them something they haven't seen."
Gorgen, St. Louis' fourth-round pick in the 2008 Draft, had been 0-2 with a 5.10 ERA in his first seven starts for Memphis. He was promoted on June 23 after making 20 appearances, including 15 starts, for Double-A Springfield.
"Absolutely, I would," Gorgen said when asked if he'd rank this as his best Triple-A start. "It would probably rank with my first start against New Orleans, but this was definitely my best."
Gorgen underwent Tommy John surgery at the end of a 2010 season in which he was 5-1 with a 1.26 ERA in 12 games for Springfield. He tried to pitch through the injury, but a postseason trip to St. Louis confirmed he would miss all of the following year.
"It's tougher on the mental side," Gorgen said. "Nowadays, with the medical advancement, there's a lot of positive advancement for guys to come out better than before. Knowing that there was going to be a light at the end of the tunnel was the mental grind."
Sam Freeman allowed two hits in the eighth and Barret Browning pitched around a hit in the ninth to finish off Memphis' seventh shutout of the season.
Pete Kozma was 2-for-3 with three RBIs and Vance Albitz doubled home a run for the Redbirds.
