Henderson undergoes shoulder surgery

MILWAUKEE -- At least Brewers reliever Jim Henderson had a smile on his face Tuesday as a tough 2014 season came to a formal end.

The former closer faces a four-month rehabilitation after undergoing surgery to clean-up the labrum and rotator cuff in his right shoulder, a procedure recommended last week after a visit with Brewers head physician Dr. William Raasch. Henderson had the surgery with Dr. James Andrews on Tuesday morning in Florida after a second opinion confirmed the diagnosis.

"Round 2!" Henderson told his more than 13,000 followers on Twitter when he posted a photo of himself smiling on a hospital bed.

Henderson also had surgery on the shoulder in 2008 when he was in the Cubs organization. He signed with the Brewers the following April and was a 26-year-old closer at Class A Wisconsin, beginning a resurgence that led to the Major Leagues in 2012 after parts of 10 seasons in the Minors, and a closer's role in 2013 after John Axford struggled. Henderson went 28-for-32 in save opportunities, and was expected to reprise the role in 2014.

Concerns about his Spring Training velocities led to a change to Francisco Rodriguez. Henderson was placed on the DL in early May after posting a 7.15 ERA in 14 games.

"It's a tough road. Rehabbing is always tough," Brewers manager Ron Roenicke said. "I'm sure he's got questions about whether he's going to come back or not. That's a tough thing to go through. Not a good year for it. Mentally, you get through it and hopefully you heal up physically and are able to get back out there." Henderson will turn 32 in October and would remain a cost-effective option for the Brewers next season if he can reclaim his velocity. He doesn't project to reach arbitration eligibility until the 2015-16 offseason.

Lohse, Garza have return dates in sight

MILWAUKEE -- Target dates were in sight Tuesday for the returns of Brewers starter Kyle Lohse and Matt Garza from injuries. The team hopes to restore Lohse to the rotation next week in San Diego after he missed a start with a sore ankle, and Garza has been put on a path to return from a rib-cage strain sometime during the first week of September.

The Brewers have been taking a particularly conservative approach with Lohse, who rolled his ankle on Aug. 2 in St. Louis and made two subsequent starts with compromised mechanics. After he exited an Aug. 13 start at Wrigley Field with renewed pain, the parties agreed it was time to get healthy.

The Brewers can get by with their four current starters through Monday's series opener in San Diego, making Tuesday's game at Petco Park a potential stage for Lohse's return.

"We want to make sure that he's right," manager Ron Roenicke said. "We know that to get this done, we have to have him at full strength."

Said Lohse, who has been able to continue throwing during his shutdown: "I need to get to where I can do what I need to do again."

Because of the nature of his injury, Garza's road back to the rotation is longer. After playing catch over the weekend at Dodger Stadium for the first time since he exited an Aug. 3 start in St. Louis, Garza long-tossed on Monday and Tuesday at Miller Park and reported positive results.

Whether he is sent out for a Minor League rehab start remains up for debate.

"We've talked about it. He may. It's either that or a simulated game," Roenicke said. "We want to see how everything works out, schedule-wise, and what's best to do at that point. We're a little bit fortunate that if it's September, which we're thinking it is [going to be], we don't have to have him go a certain length to really be important like you would normally because you'd burn up your bullpen. If we have some extra arms [among September call-ups], we feel if he goes three innings, he goes three innings. Wherever we need him to go."

Brewers form Creative Council

MILWAUKEE -- In an effort to better appeal to budding baseball fans, the Brewers this week introduced the "Brewers Creative Council," a team of young professionals that will help develop and evaluate future promotions and marketing strategies.

The team's director of new media, Caitlin Moyer, will lead the group.

"The best ideas sometimes come from outside sources," Brewers COO Rick Schlesinger said in a statement. "The Brewers Creative Council will give us the opportunity to learn from a diverse group of fans as we continue to enhance the Miller Park experience."

The council includes David Cohn of the Wisconsin State Golf Association, Josh Derouin of PKWARE, Lauren Hill of the University of Wisconsin-Milwaukee, Arthur Ircink of Wisconsin Foodie, Tarik Moody of 88Nine RadioMilwaukee, Andy Nelson of the Pabst Theater Group, Kathryn Reinardy of the Milwaukee Symphony Orchestra and Joel Tilleson of Falk Legal Group.  

Last call

• Second baseman Scooter Gennett was encouraged by a baserunning session on Tuesday in which he ran full speed for the first time in several weeks. He's been playing on a sore right quadriceps since just after the All-Star break.
