The son of longtime pro Russ Cochran, Case shot 69 in the qualifier, which spilled into Tuesday because of severe weather one day earlier. That put him in a four-man playoff for three spots in the field.
After two of those spots were claimed by Jason Allred and Chris Thompson, Cochran reached a fifth playoff hole with Chris Parra.
He used a 7-iron from 152 yards to ace the hole and get into his first career PGA Tour event.
"He told me he didn't see it go in,” said Russ Cochran, who’s currently playing on the Champions Tour. “Once he got on the green, he saw his ball mark six feet from the hole and had a good feeling. Sure enough, it was in the hole.
“He's super excited. He's been playing well on the Adams Tour and I knew he was feeling good about his game. It will be his first PGA Tour event and he's pumped up."
