"Nice to have him in the lineup," Roenicke said. "It made a difference last night when he's not in that lineup going into extra innings, trying to get one run, and he's not out there."
The Brewers lost to San Francisco, 4-3, in 14 innings, and they didn't score after Braun's two-run blast tied the game at 3 in the eighth inning.
Braun wasn't sure if he'd be able to play Tuesday following Monday night's game, opting for a wait-and-see approach. He also said the tight groin was similar to an injury he suffered in Spring Training.
"A little different area," he said Monday. "It's not as bad as it was then, so it's not too serious."
Along with the nagging groin, Braun missed one game earlier this month after leaving a May 2 contest against the Giants with a sore right Achilles tendon. Roenicke's biggest concern with such little injuries is that they might diminish the left fielder's versatility, which is what he said makes Braun so special.
"When you're taking away a little part of his game, it bothers me because I know how much he can do to help you win," Roenicke said. "He can steal a base and get on second, and a base hit maybe scores the winning run. He certainly can drive the ball, which we know that. ... We need him a hundred percent. And that's what we talked about today, whether he wanted to play again, and he felt like he needs to go back out there for our lineup to work."
