Lack of playing time of no concern to Overbay

CHICAGO -- Lyle Overbay has seen his playing time decrease as the first-base platoon swings more toward Mark Reynolds, but doesn't plan to make a stink about it.

"I told [manager Ron Roenicke] from the beginning, I'll be ready whenever," Overbay said. "We're winning. I know I don't have anything else to prove; I just want to win a World Series."

Overbay has been effective as a pinch-hitter, batting .412 in that role entering Monday's series opener at Wrigley Field, but was limited to three at-bats during the Brewers' recent six-game homestand. He's been limited to 27 plate appearances since the All-Star break.

Reynolds entered Monday with 61 plate appearances since the break, and with his solo homer in the second inning, sealed his seventh consecutive season of 20-plus home runs.

"We envisioned coming into the season that [Reynolds] would get most of the [playing time], but I did leave it open to who was swinging better and try to get them in," Roenicke said. "Lyle was swinging better for a while, and I played him more. But it's been both matchups, plus [Reynolds] is outstanding defensively, which makes it easier.

"We put a bunch of guys [at first base] last year that never even played the position, and we suffered for it defensively. This year we're saving runs at that position. I think it's really important to have a good defensive first baseman. I think what it does to your pitching staff, to your infielders, giving them confidence -- it's really important. Usually, your big basher goes to first because he can't play somewhere else. I don't agree with that."

Rogers tees off in Triple-A doubleheader

CHICAGO -- Jason Rogers, the reigning Brewers Minor League Player of the Year, had a pretty good week at Triple-A Nashville -- and we're just talking about Sunday.

Rogers homered three times and drove in nine runs during the Sounds' doubleheader sweep of Round Rock. Two of the homers and six of the RBIs came in Game 1, and he hit a three-run homer in Game 2. Including those games, Rogers has hit safely in 12 of his last 18.

Overall, he is hitting .288 with a .357 on-base percentage this season between Double-A Huntsville and Nashville. He has 14 home runs and 71 RBIs in 115 games.

"I never actually saw him play until he got called up to Triple-A, but my first impression was, he's definitely a guy with a lot of power," said right-hander Mike Fiers, who was promoted to the Major Leagues last week. "I feel like he knows the strike zone, and he's a good hitter. He's a big guy, but he's not just a guy that swings and hacks at everything -- he knows the strike zone. He usually puts the ball in play.

"I remember the first game, he hit a ball over the center-field wall, and I don't think I've ever seen that in the parts of four years that I've been in Nashville. I've never seen a guy hit a ball over that. It was insane. Great power."

Rogers is a candidate for a September callup because he is already on the 40-man roster and is versatile defensively. He has played first base, third base and the outfield in the Minors.

Third base is in limbo in Milwaukee beyond this season because incumbent Aramis Ramirez is in the final guaranteed year of his contract. Rogers has played 103 games at the position, appearing there for 37 of his 38 games with Nashville.

"The times I saw him, he was solid at third base. He gets it done," Fiers said. "He's one of those guys that he's not the most flashy, but when it comes down to it, he played a really decent third base."
