But on Friday, the 22-year-old will finally get a chance to throw at his team's home stadium.
"I'm definitely excited," said Corbin, who will face the Giants in the opener of a three-game series at Chase Field. "It's good to be here. I've never thrown here before. Definitely looking forward to it. I got to see one Spring Training game here, and I've been to a couple other games, but that's it."
Corbin said he enjoyed his family watching him pitch, but it'll be nice to have the whole stadium on his side this time around, instead of just a section.
"I'm sure it'll be fun to get cheered for," he said. "Some of the fans [in New York] gave my friends and family some stuff, but they handled it pretty well. This time will be a little better."
In his first two starts of his career, against the Marlins and Mets, Corbin has allowed seven earned runs on 13 hits in nine innings.
In his two bullpen sessions in between starts, Corbin has worked on his mechanics and keeping his off-speed pitches down.
"It's been a little overwhelming, but I'm starting to settle down and get used to some things," he said. "It's exciting and I'm glad to be here, but it's still baseball and you have to go out there and compete."
