Braun bounces back, returns to lineup

MILWAUKEE -- When Ryan Braun left Monday night's game against the Giants in the 10th inning with a tight right groin, Brewers manager Ron Roenicke missed his powerful slugger. Fortunately for Roenicke and Milwaukee, the reigning National League MVP was back to his usual spots in left field and third in the batting order for Tuesday's game against San Francisco at Miller Park.

"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."

Hart takes break after 14-inning game

MILWAUKEE -- One night after his second career start at first base, Corey Hart was out of the Brewers' lineup Tuesday night against the Giants.

It was just a routine off-day for Hart, who has played in 41 of 43 games this season, including Monday night's 14-inning, 4 1/2-hour marathon contest. Hart's last off-day came April 11 in Chicago.

"I got two good games in yesterday," Hart said Tuesday. "So maybe I'll get my third game in tomorrow."

Hart's off-day was facilitated in part by the fact that left fielder Ryan Braun was back in the lineup after leaving Monday's game early with a slight groin injury. Had Braun needed a day off, Hart likely would have been back in right field.

Brewers manager Ron Roenicke had been discussing with Hart the possibility of getting him out of the lineup for a while, and Tuesday presented a good opportunity for it.

With Hart playing 14 innings at a new position Monday night, he was likely a bit more sore than usual. His numbers against Matt Cain (2-for-16 with three strikeouts) also are less favorable than those for Hart against lefty Barry Zito (6-for-15 with a home run), who will start Wednesday's series finale.

"As much as I hate to get him out of the lineup," Roenicke said, "I think it in the long run it will help him."

Gamel undergoes knee surgery

MILWAUKEE -- Brewers first baseman Mat Gamel underwent season-ending surgery on his torn right ACL on Tuesday morning. Dr. William Raasch, who performed the surgery, also cleaned up the lateral meniscus in Gamel's right knee.

Before sustaining the injury in a 2-0 loss to the Padres on May 1, the 26-year-old first baseman was batting .246 (17-for-69) with six RBIs and one home run in 21 games this season. Since Gamel went down, Milwaukee has started four different players at first base, including Corey Hart on Monday night.

Gamel is the second Brewer to undergo the season-ending procedure in less then a week, as shortstop Alex Gonzalez had his torn right ACL repaired Thursday.

Brewers' pitching shines despite loss

MILWAUKEE -- Outside of the first and last innings, the Brewers pitched as well Monday night as they have all season.

Between the one-out Buster Posey home run in the first and Hector Sanchez leading off the 14th with a homer, the Giants did not score a run. That stretch of 12 2/3 scoreless innings is the longest of the season for the Brewers.

The catalyst for that stretch was Randy Wolf, who turned in an excellent start after walking two batters on nine pitches and making a mistake to the next hitter, Posey.

"Wolfy, after that first inning, outstanding," said Brewers manager Ron Roenicke. "To give us seven innings after that start, I thought that was an outstanding outing."

Following Wolf, four straight Brewers relievers -- Francisco Rodriguez, John Axford, Jose Veras and Manny Parra -- continued to blank the Giants. Rodriguez and Axford delivered scoreless innings in the eighth and ninth, while Veras and Parra shut the Giants out in two innings apiece from the 10th to the 13th.

Those five Brewers pitchers also combined for 11 strikeouts against four walks, while limiting the Giants to just six hits over that nearly 13-inning stretch.

"Our bullpen did a great job," Wolf said after Monday's game. "It's unfortunate that we came up on the losing end of the game.

"Today I think was a game that we played good baseball. We came up on the losing end, but the pitching did a good job today. It was a tough battle that we lost."

Last call

Catcher Jonathan Lucroy and starting pitcher Yovani Gallardo took on the roles of Southwest Airlines employees at Milwaukee Mitchell International Airport on Tuesday afternoon. Gallardo said the two did everything from help escort planes on the runway to scan tickets for passengers, and he didn't think he was cut out for the gig.

"It's a lot of hard work for those guys and girls," he said. "But we got to meet all different kinds of people and had a good time doing it also."
