"I got thrown into a tough situation and I just treated it as the seventh or the eighth inning because runners were already on and we just had to get outs," Petricka said.
On the second pitch of the at-bat, Petricka lifted his left leg to start his windup, but spun toward second base, where pinch-runner Jarrod Dyson had veered too far off the bag. Third baseman Marcus Semien tagged Dyson out for the second out.
"In the game, [catcher Tyler] Flowers said, 'If I give you a certain sign, just be ready to do the spin move.' He gave me the sign, so I just knew beforehand that pitch wasn't coming home at all, so I just did my best to sell it to the runner like I was going home," Petricka said.
Ventura opted for Petricka in the tight spot because of his tendency to induce ground balls.
Petricka's 65.2 percent ground-ball rate ranks sixth in the Majors among pitchers with at least 20 innings.
Through 44 games, Butler's ground ball rate sits at a career-high 57.2 percent.
Petricka fell behind, 2-0, before working his way back and getting a ground out to second.
"The first two pitches, I tried to be too fine, and I kind of realized that and I thought, 'It's time to go after him and make him hit it,'" Petricka said.
