ST. LOUIS -- Cardinals catcher and four-time All-Star Yadier Molina was once in Martin Maldonado's shoes -- young and eager to prove his ability.

Having been in that position before, the 30-year-old Molina is not quick to put much stock into Maldonado's difficult day behind the plate in the Brewers' 9-3 loss to St. Louis on Friday night. Maldonado, who had committed three errors in 50 games this season, matched that number with a career-high three on Friday.

"He's one of the best catchers I've ever seen, to be a rookie," Molina said after Friday's game. "He's like me. When I came over here, I tried to be so aggressive. I tried to show my arm. Those things are going to happen. But he's going to learn."

All three of Maldonado's miscues were throwing errors. Twice Maldonado missed the mark on attempted steals by Molina, as both of those throws rolled into the outfield. Maldonado said each error was simply a result of trying too hard.

Both Maldonado and Molina are from Puerto Rico, and work out together in the offseason. Maldonado said Molina and his brothers Jose and Bengie -- both Major Leaguers, as well -- have had major influences on his game.

Maldonado said the Molinas have helped him with calling games, as well as how to stay focused and learn from mistakes.

"Every time you do something bad or good, you learn from it," said the 25-year-old Maldonado. "I think that's one of things that when I look back, I think of what I did bad and try to make it better the next time."

Brewers go retro in celebration of 1982

ST. LOUIS -- The Cardinals celebrated the 30th anniversary of their 1982 World Series championship on Saturday night, in which St. Louis defeated the Brewers in seven games.

Though many longtime Brewers fans may not want to recall narrowly missing out on the Brewers' first and only World Series title, Milwaukee participated in the festivities, as well. The Brewers donned 1982 powder blue "road" uniforms, courtesy of Majestic, as St. Louis wore their 1982 white "home" jerseys.

Closer John Axford said before Friday's game that he's a fan of the throwback style and powder blue color. However, Axford also hadn't tried his jersey on yet and was a little concerned with how the jersey's material breathes.

"They're a little thicker than normal," Axford said. "It's a little scary, judging by how much I was sweating in shorts and a t-shirt outside. Wearing that I'm assuming I'm probably gonna sweat a little more, just sitting there doing nothing."

Brewers manager Ron Roenicke has had plenty of experience with powder blue in the past -- playing college ball at UCLA and spending two years in Philadelphia in the 1980s. Roenicke said he'd prefer to wear the Brewers' everyday jerseys for both comfort and style reasons, and would like for the retro style to stay in the past.

"I'm hoping we're better without designs now than we were in 1982," he joked.

Braun closing in on 20-20 season

ST. LOUIS -- He's not getting too far ahead of himself just yet, but Ryan Braun is quickly approaching a career milestone. Braun needs one more stolen base to produce the ninth 20-20 season in franchise history and the third of his career.

While Braun isn't one to dwell on those kinds of things during the season, it's an achievement he can certainly appreciate.

"With two months left, I hope I can," Braun said. "But during the year I rarely take time to step back and reflect on those things. But whenever you've done something that has been done before in the history of an organization, it's pretty special."

Braun leads the National League with 29 homers, one away from recording his fifth career 30-homer season.

"He's got so many tools that can help you win," said Brewers manager Ron Roenicke. "It makes a lot of difference when a guy can run when the defense has to do to try and protect against that good speed."

Last call

• Aramis Ramirez was out of the Brewers' starting lineup for the second straight game, after receiving a cortisone injection on Thursday for a sore left wrist. Roenicke said Ramirez will take swings during Saturday's game and if his wrist feels OK, he would be available to pinch-hit.

• Reliever Manny Parra played catch on Saturday for the first time in more than a week while recovering from a left shoulder impingement. Roenicke said Parra threw at a distance of about 60-70 feet, and will lengthen that distance and throw again on Sunday.

• Nyjer Morgan batted second and started in right field on Saturday. Morgan entered the game a career .471 hitter in 17 at-bats against St. Louis starter Adam Wainwright. Roenicke said that Morgan will likely start on Sunday, as well, considering Morgan's success against Sunday's starter Kyle Lohse. Morgan is 4-for-11 lifetime against Lohse.
