"It's the best feeling of my life," Gindl said before the game.
The Brewers promoted Gindl after placing left fielder Ryan Braun on the 15-day disabled list. At 24, Gindl became the youngest of the Brewers' six players to debut when he struck out against the Reds' Homer Bailey in the seventh inning.
He is used to that label. Gindl was a Brewers' fifth-round Draft pick in 2007 out of Pace High School in Florida, and he was 22 when he debuted in Triple-A in 2011. He had been waiting there patiently for a promotion.
"The last two weeks, he has really swung the bat well," Brewers manager Ron Roenicke said. "He hangs in there, gives you a nice at-bat. Especially right now, because he's got a lot of at-bats under his belt [from Triple-A], I think he'll be a good pinch-hitter for us for a while. Now, how long that lasts, that he's good without me starting him, I don't know. That's always hard to predict. But he does all the things well that you want from a bench player."
Gindl was batting .274 at Nashville with eight home runs and a team-best 38 RBIs. He hit .364 over his last 10 games and got the call over Davis, who was hitting .125 over his last 10 contests.
"We try to go by whoever is doing the job, and [Gindl] is swinging the bat the best down there, and we know he plays pretty good defense," Roenicke said.
