Chicago ? The Chicago Cubs might have lost more than just their brief hold on first place.

Adrian Beltre homered and drove in a season-high four runs, leading the Los Angeles Dodgers over Chicago 10-5 Saturday.

Jeromy Burnitz also homered for the Dodgers, who roughed up an ailing Kerry Wood and snapped Chicago’s four-game winning streak. One day after moving into first place, the Cubs slipped a half-game behind Houston in the NL Central again.

Wood left in the third inning with back pain.

“He wasn’t really 100 percent. He’s got a lower back problem, he’s had it his last couple of outings,” Cubs manager Dusty Baker said.

Baker said he might skip Wood in his next scheduled start at Houston Thursday in favor of Shawn Estes. Friday, Baker decided Estes would skip his next start.

“We’ll see how he is,” Baker said. “Now we have the option.”

Wood did not talk to reporters after the game and will be re-evaluated today.

“(Wood) is not going to tell you unless it is really bad,” Cubs general manager Jim Hendry said. “I’m sure today he had some discomfort, obviously it looked like he was laboring more than normal. Hopefully, he will be OK and feel a lot better tomorrow.

“It’s been one of those things that comes and goes with him sometimes.”

Jim Thome waves to the crowd after blasting a two-run homer in the sixth inning. The Phillies beat the Cardinals, 5-4, Saturday in Philadelphia.

Shawn Green had three hits and two RBIs, and Dave Roberts rapped three hits and scored three times.

Aramis Ramirez hit a pair of two-run homers for the Cubs.

Brewers 6, Pirates 4
