CINCINNATI -- Rickie Weeks replaced an injured Ray Durham in the lineup Saturday as the slumping Brewers lost one of their few hot hitters.

Weeks made his 114th start, but his first while hitting anywhere other than the leadoff hole. Mike Cameron remained in that spot for the fifth straight game, and Weeks batted seventh.

Durham strained his right hamstring in the early innings of Friday's loss to the Reds, but it was unclear whether he was originally hurt while he was caught stealing in the first inning or while striking out in the third.

He was not accessible to reporters after Friday's game or before Saturday's game to discuss his injury. Durham spent most of Saturday in the training room.

"It was bad enough to where he felt that he needed to come out of the game," Brewers acting manager Dale Sveum said. "We'll take more of a look at it today and [Sunday], then give him the off-day [on Monday] to get through it. We'll see if he can maybe at least hit today, and then we'll pinch-run for him."

Third baseman Craig Counsell took Durham's spot in the two-hole. Sveum has diminished Weeks' role since taking over for former manager Ned Yost this week, and met with Weeks earlier this week to explain his changes.

Durham had become the starter against right-handed pitchers. Weeks was to start against left-handers.

A first-inning single Friday extended Durham's hitting streak to six games, and he was hitting .387 (12-for-31) with seven RBIs over his past 11 games. Add Durham's sudden absence to the list of headaches for Sveum.

"It hasn't been easy my first four days," Sveum said. "A lot of stuff has happened. Two out of my [first] four days, the pitcher went two innings, then the second baseman goes down. It's like, 'This is awesome!'"
