"I knew with my thumb that it's just going to be there; it's not going to magically disappear. And aside from that, everybody deals with different things throughout the course of the season," Braun said. "It just happens. Most of the time, when you're able to get through them, you guys don't know about 90 percent of the stuff that all of us deal with unless guys don't play."
Braun's back began to spasm during batting practice on Saturday afternoon, but with the Brewers bidding to snap a four-game losing streak, he asked to remain in the starting lineup.
After one inning, manager Ron Roenicke was forced to replace Braun with Logan Schafer.
"I didn't like yesterday," Roenicke said Sunday morning. "I talked to [Braun] before the game, and I told him, I said, 'I don't want you in there if I'm having to take you out of there.' Because you set up a lineup for certain personnel, and when a guy comes out of a lineup or you think he has a good chance of coming out of a lineup, now I've got two left-handers [Scooter Gennett and Schafer] back-to-back, which now allows them to bring in their two left-handers if it works out in the game, to get your two lefties. That's not an ideal way to do it."
Braun received multiple rounds of treatment on Saturday night and Sunday morning. He will be evaluated again on Monday, when the Brewers begin a homestand against Cole Hamels and the Phillies.
Braun is hitting .327/.397/.558 in his last 13 games, including an eight-game hitting streak that ended Friday.
"There's never a good time for any injury, but obviously I've felt better over the last couple of weeks," Braun said. "I've swung the bat really well. I've gotten healthier. Things are going well, so hopefully a day or two, just a minimal thing, get right back in there and keep doing what I've been doing."
