Davis making little progress on DL

MILWAUKEE -- Brewers left-hander Doug Davis' stay on the 15-day disabled list has no end in sight.

Davis is still bothered by tendinitis in his left elbow and has not pitched since July 9, when he returned from a separate stint on the DL caused by pericarditis, a painful swelling of the tissue around the heart. An MRI scan of Davis' elbow revealed no structural damage, but the inflammation has yet to subside.

"It's not getting any worse," Davis said. "It's not getting any better, either. I'll go a few days feeling great and say, 'OK, here we go.' Then I wake up the next morning all stiff. I just can't get over that hump."

The Brewers signed Davis in January for a second stint in Milwaukee partially because of his durability, but have gotten only eight starts and 38 1/3 innings out of him so far.

Rookie Cain jumps right into action

MILWAUKEE -- Typically, a rookie gets some advance notice before making his first Major League start. Not Lorenzo Cain.

"I didn't get that," Cain said with a big smile. "I got here, saw my name in the lineup. Let's get it going. I'm excited. I'm pumped to get my first start under my belt."

The Brewers recalled Cain from Triple-A Nashville on Friday afternoon after placing another outfielder, Carlos Gomez, on the disabled list with a concussion. Cain was put right to work as the starting center fielder and six-hole hitter for Friday's series opener against the Astros at Miller Park.

He went 1-for-3 with a run scored before being lifted for pinch-hitter Jim Edmonds in the eighth.

Cain made five plate appearances with the Brewers during his first stint with the team from July 16-21, all off the bench.

"He came up and did very well, so it will be interesting to see how he does here," manager Ken Macha said.

Gomez is having a disappointing first season with the Brewers, batting .228 with a .286 on-base percentage in 75 games. His underwhelming performance has led some to call for Cain to make a permanent leap from the Minor Leagues, where he has batted .317 this season with a .402 on-base percentage and an .834 OPS between Double-A Huntsville and Triple-A Nashville.

Those calls have grown stronger with the success of catcher Jonathan Lucroy, who had only 80 at-bats at Triple-A before an emergency promotion to Milwaukee to replace the injured Gregg Zaun. Lucroy is holding his own in the Majors, with a .269 average, two home runs and 10 RBIs in 38 games.

But Macha would like to see Cain put in more time at Triple-A, where he has 87 at-bats in 22 games. "The other thing is 'Luc' played in the Fall League, and that's a highly competitive league out there," Macha said. "There's a lot of prospect pitchers out there. Not that guys aren't able to go from Double-A to the big leagues. ... The at-bats [Cain] had were all pretty good. I think he's going to give us good at-bats against left-handed pitching."

Cain will probably start again Sunday with left-hander Wesley Wright pitching for Houston. He'll share time in center field with left-handed veteran Edmonds, who has been hobbled by a sore right Achilles.

Worth noting

Brewers catcher Jonathan Lucroy didn't start Friday because he spent most of the day with his growing family. Lucroy became a dad when his wife gave birth to a healthy baby girl, Ellia Elisabeth, in Milwaukee. Dad made it to the ballpark in time to catch the game's ceremonial first pitch. ... On Sunday, Brewers general manager Doug Melvin and his wife, Ellen, will host an event called "The Pink Tie Guy" at Bacchus, 925 E. Wells St. in Milwaukee. The proceeds from the event will benefit the Southeast Wisconsin Affiliate of Susan G. Komen for the Cure, an organization that raises funds for breast cancer research. Special guests at the event will include Major League Baseball Commissioner Bud Selig, Brewers principal owner Mark Attanasio and radio broadcaster Bob Uecker, among others. Tickets for the event are $1,000 per couple and more information can be found by contacting Brewers Community Foundation Director Cecelia Gore at 414-902-4544.
