MIAMI -- Ryan Braun was not among the nine names Brewers manager Ron Roenicke wrote on Monday's lineup card.
Braun, who left Sunday's game against the Phillies in the bottom of the third inning, will rest his sore right thumb on Monday while his teammates face the Marlins. With an off-day scheduled for Thursday, there is a chance the All-Star outfielder will not start any of the three games in Miami.
"We'll go day to day and see how he's doing," Roenicke said. "He's going to play some catch, but he's not going to take BP today. He's available if we have to use him. Then it becomes a decision of whether I think the at-bat has a chance to set him back and how important the at-bat is."
Braun has battled pain in his right hand for about a month. Though he does not remember the exact day it began hurting, he does recall that it came on a swing. When it originally happened, Braun says his hand was numb for about a week before he regained feeling."
"It's not just my thumb, it's my hand," Braun said. "There's a nerve and a ligament in my hand that is an issue. The majority of it is between the index finger and my thumb."
The 29-year-old has made several adjustments to try and play through the pain, but has not had the results he would like.
"I've dealt with it and tried to fight through it," Braun said. "A couple times it has gotten a little better, but it's so easy to irritate and aggravate. Every time I swing, there is a high likelihood that I am going to continue to irritate it. It's just a matter of getting it close to the point where it's close to healthy."
Braun feels he has been "swinging with close to one hand at 60 or 70 percent for the last month." He has hit .289 over the past 26 games, but has homered just once and driven in only 10 runs in that span.
"I've tried to change the way I hold the bat and tried to change my bat path," Braun said. "I've tried to do a lot of different things to compensate for the pain and get it to the point where it doesn't hurt when I swing, but I haven't been successful doing it. We're at the point where I need to get back close to being healthy, so I can take a regular swing and hold the bat the way I regularly do."
While Braun could miss the entire Marlins series, he and Roenicke both hope the star outfielder will be able to avoid a trip to the disabled list.
"We'll wait and see what happens," Roenicke said. "We haven't talked about doing that yet. Hopefully it won't come to that."
Narveson's rehab progressing; Burgos scratched
MIAMI -- The Brewers have several players working back from injury, and some are closer to a return than others.
Chris Narveson made his third rehab start for Triple-A Nashville Sunday, allowing three runs on five hits over 4 1/3 innings. He struck out four and did not walk a batter while throwing 63 pitches.
The left-hander is slated to make four rehab starts before the Brewers consider activating him from the disabled list. Narveson is stretching out like a starter, but Roenicke is not sure what his role will be once he is ready to return to the big leagues.
"We're going to have to look at it when the time comes," Brewers manager Ron Roenicke said.
Hiram Burgos is working back from a right shoulder impingement. The right-hander was scheduled to make a rehab start Monday with Class A Wisconsin, but he felt some stiffness in his shoulder recently and had his rehab start pushed back.
"He's playing catch today and is supposed to have a bullpen tomorrow, then we will re-evaluate," Roenicke said. "Hopefully, he is good and we can get him pitching in games."
Corey Hart, who has been out all season recovering from knee surgery, traveled with the Brewers to Miami. The first baseman is still not close to a rehab assignment, but Roenicke has seen progress lately.
"We're still a ways away, but he's here, so he can get all the work he needs as far as running bases and taking some ground balls," Roenicke said. "He is moving better but it's a slow process."
Brewers sign third-round Draft pick Astin
MIAMI -- The Brewers have agreed to terms with one of their top Draft picks.
According to Baseball America's Jim Callis, the Brewers have agreed to terms with third-round pick Barrett Astin. Callis reports the team signed Astin for a $584,300 bonus.
Astin played collegiately at Arkansas and was a key member of the Razorbacks squad that made it to the College World Series in 2012. He led the '12 team with 11 saves, amassing a 1.99 ERA and 61 strikeouts while pitching in a team-high 32 games.
The right-hander moved into Arkansas' starting rotation this past season, posting a 1.79 ERA to go with his 4-4 record and 74 strikeouts over 90 2/3 innings.
Brewers scouting director Bruce Seid said the team would send Astin out as a starter to begin his pro career, but left open the possibility of moving him to relief later on.
