To make room for Swindle, the Brewers optioned right-hander Mike Burns to Nashville. Burns was 2-3 in five starts with a 7.20 ERA, prompting the Brewers to send him down.
Swindle, along with current left-handed specialist Mitch Stetter, gives the Brewers two lefties coming out of the bullpen as they prepare to face two powerful left-handed sluggers in Washington's Adam Dunn and San Diego's Adrian Gonzalez.
"It was good to get another lefty," Brewers manager Ken Macha said. "You have to have a way of [getting through] the sixth inning and not burning your only lefty."
Swindle allowed four runs in 2 2/3 innings over two brief stints with the big league club this year, but has been nearly unhittable at Nashville. In 31 relief appearances there, he posted a 1.03 ERA with a 0.98 WHIP. Left-handed hitters are hitting .148 against Swindle, who elicits 'oohs' and 'ahhs' with his super-slow curveball.
