MILWAUKEE -- With starting shortstop Tommy Manzella out for about five more weeks with a fractured left index finger, the Astros are relying on rookie Oswaldo Navarro and veteran infielder Geoff Blum to split time at shortstop and are not looking outside the organization for help at the position.
"We're comfortable giving Geoff playing time over there and as is the case with [Chris] Johnson and [Jason] Bourgeois and [Jason] Castro, we have to find out about Ozzie," general manager Ed Wade said. "He's only about 26 years old, and if he can show the steady play he showed at [Triple-A] Round Rock at this level, then it behooves us to give him a shot instead of somebody with experience that doesn't carry the upside because of age or whatever.
"Right now we're not actively looking for a shortstop. That said, if something came along we thought would make sense, we'd pursue it."
Navarro was recalled from Round Rock when Manzella went on the 15-day disabled list. He was hitting .298 with four homers and 26 RBIs and a .400 on-base percentage in 44 games for the Express. The Astros signed him to a Minor League contract in December.
Johnson struggling on defense
MILWAUKEE -- Rookie third baseman Chris Johnson made five errors in his first five games since being recalling from Triple-A Round Rock last week.
It didn't help that Johnson was playing on a choppy infield last weekend in Arlington, and he had at least one error last week that probably shouldn't have been charged to him.
Still, general manager Ed Wade remains confident in his defensive abilities.
"He's got the tools to be very consistent defensively," Wade said. "He's got to tighten it up, but to his credit and the credit of [manager Brad Mills] and [first-base coach] Bobby Meacham, they're working on it every day.
"He needs to focus on being as consistent as he could possibly be. He's got some tough errors, and think he's gotten some errors he didn't deserve, to be honest with you. At the same time, there have been balls he's got to play cleanly and he hasn't. But we know he's capable."
Mills expects sharper defense from Johnson once he gets more comfortable.
"In Spring Training, he showed some good defensive work for us, and the reports on him in Round Rock were pretty good," Mills said. "It's kind of surprising a little bit. He's made some good plays as well, but to finish them is another thing."
Feliz starts in place of Berkman
MILWAUKEE --- Pedro Feliz, who lost his starting third-base job to rookie Chris Johnson last week, made his first start at first base since April 17. Feliz started Monday in place of slugger Lance Berkman, who had started 12 consecutive games since June 13.
"[Berkman] had an off-day in New York [on June 13], which if you look at everything is not that long ago, but at the same time we're coming off a tough series in Texas where the heat was tough, and it took a lot out of guys," manager Brad Mills said. "Hunter [Pence] had a day off, [Jeff] Keppinger got a day off and Carlos [Lee] got some rest because of the designated hitter.
"This was just a good time to be able to get him a good day off."
Berkman entered Monday having played in 61 of 64 games since coming off the 15-day disabled list April 20. He's hitting .318 in his career against Milwaukee with 25 homers and 93 RBIs, and his 15 career homers at Miller Park are tied for the second among active Brewers opponents.
Feliz started four games at first base in the first part of April when Berkman was on the disabled list. He batted sixth against Brewers left-hander Manny Parra on Monday, with Johnson hitting fifth.
Astros reveal 'All-Stars Among Us' winner
MILWAUKEE -- Shane Wallace, a police officer in Victoria, Texas, is the Astros winner of the Major League Baseball and PEOPLE magazine "All-Stars Among Us" campaign, which debuted in 2009 and recognizes individuals who are serving their communities in extraordinary ways.
Wallace created the city's Blue Santa program, which provides toys, clothing and other gifts to needy children and their families each Christmas. Last year, 484 kids enjoyed Christmas gifts because of Blue Santa. Wallace and other officers escort Blue Santa to children's homes with lights and sirens.
The 30 community leaders -- one from each team -- will be honored at the 2010 All-Star Game on FOX and featured in a special pregame ceremony on July 14 at Angel Stadium in Anaheim. In addition, one of the winners will be featured in the July 19 issue of PEOPLE, which hits newsstands during the week of the All-Star Game.
"I think it's pretty awesome," Wallace said. "It's a dream come true. I always wanted to go to the All-Star Game, and it's a good way of getting the word out for the Blue Santa program. Already, a lot of people have come up to me that hadn't heard of it. I'm a winner either way, regardless of what the voting was."
Fans across the nation cast 1.7 million votes -- more than double the amount of votes from the previous year -- at PeopleAllStars.com to select the 30 "All-Stars Among Us" winners out of the pool of 90 finalists who are serving as leaders within their communities.
