Derrek Lee homers twice, Chicago Cubs clobber Lohse and St. Louis Cardinals 9-7

Derrek Lee homered his first two at-bats, helping the Chicago Cubs pummel Kyle Lohse and knock the St. Louis Cardinals out of first place in the NL Central with a 9-7 victory on Sunday.

Ryan Dempster (11-8) won his third straight start for the Cubs, who have won only four of 18 but took two out of three against a team that had grabbed the division lead with a three-game sweep at Cincinnati. The Cubs won consecutive games for the first time since July 23-24 against the Cardinals at home.

Albert Pujols became the first player to hit 30 homers in his first 10 seasons when he belted a drive to straightaway center in the first. The St. Louis slugger has homered in seven of his last 13 games to give him 396 for his career, tied with Joe Carter for 50th place.

The Cardinals are 10-5 against the Reds, back in the lead after beating Florida 2-0, but have struggled against the also-ran Cubs (4-5) and Astros (5-7). St. Louis is 48-25 when Chris Carpenter, Adam Wainwright or Jaime Garcia pitches, and 17-26 in other games.

Lee homered to straightaway center in the first and third against Lohse (1-5), making his first start after being activated from the 60-day disabled list following forearm surgery. Some fans in the sellout crowd of 44,074 that featured a healthy Cubs contingent booed Lohse, who allowed seven runs to hike his ERA to 6.89, as the right-hander trudged to the dugout.

Lee, batting .429 (9 for 21) with two homers and five RBIs against Lohse, left after four innings due to lower back stiffness. He has 16 homers on the season after hitting four solo shots in the series, connecting in each game.

The first five Cubs reached safely to start a six-run fourth that chased Lohse, including a two-run double by Koyie Hill and an RBI single from Dempster. Marlon Byrd had two singles and an RBI in an inning that matched the Cubs' season bests for runs and hits (six).

The Cubs were patient at the plate in the fourth, swinging at only two of the last 23 pitches from Mike MacDougal.

Dempster allowed two runs and five hits in 6 2-3 innings. He has won three straight starts for the first time since Aug. 10-23, 2008.

Pujols is heating up in August once again. It's traditionally his best month, with career totals of 76 homers, 342 hits and 220 runs. He also is batting .319 (15 for 47) against Dempster with six homers and 12 RBIs.

The Cardinals scored five times in the ninth to make it interesting, starting with rookie Steven Hill's first career homer and ending with Hill's game-ending groundout against Carlos Marmol with two men aboard. Pinch-hitter Felipe Lopez, who had been in a 2-for-32 slump, delivered a two-run single.

Marmol earned his 21st save in 25 chances.
