Cincinnati ? After making outs in his first two at-bats, Todd Walker quickly reverted to his recent form.

Walker had hits in his final four at-bats and drove in four runs, including a tiebreaking three-run double in the eighth inning, propelling the Cincinnati Reds past the Chicago Cubs 15-12 on Thursday night.

Cincinnati's Wily Mo Pena is congratulated by Aaron Boone, left, and Ray Knight, right, after Pena hit his first major-league home run during Thursday's game in Cincinnati.

Walker is 20-for-35 during an eight-game hitting streak.

“Todd Walker’s been our hottest guy for quite a while,” manager Bob Boone said. “Everybody had a hand in this one.”

Chicago outhit the Reds 22-17, the Cubs’ most since collecting 24 against Houston on Aug. 20.

The last major league team to get 22 hits and lose a nine-inning game was Oakland on April 27, 1980, according to the Elias Sports Bureau. The Athletics lost that game 20-11 at Minnesota.

The last time Cincinnati allowed 22 hits in a game was in a 13-5 loss at Los Angeles on June 3, 1988.

“It was kind of a weird night,” Walker said. “We came out on top, so it’s a good thing for us.”

Trailing 12-11, Cincinnati tied it in the eighth on a wild pitch by Kyle Farnsworth (3-6) with a runner on third before Walker’s bases-loaded double gave the Reds the lead.

John Reidling (2-2) struck out the final batter in the eighth, and Scott Williamson got three outs for his third save.

Astros 6, Cardinals 3

Houston Jose Vizcaino hit a three-run homer to cap a four-run rally in the eighth inning, and Houston stopped St. Louis’ eight-game winning streak.

Houston, which closed within 5 1â2 games of the NL Central leader, trailed 3-2 in the eighth when Craig Biggio homered off Dave Veres (5-8) leading off.

Jeff Bagwell singled with one out, and Mike Crudale relieved and walked Mark Loretta. Vizcaino followed with his fifth homer of the season.

Octavio Dotel (6-4) pitched a two-hit eighth, and Billy Wagner finished for his 32nd save in 38 chances.

Mets 8, Expos 2

Montreal Jeromy Burnitz homered twice and had three RBIs and Mo Vaughn hit a two-run homer, helping Jason Middlebrook (2-3) win his New York debut.

A late addition to the starting lineup, Vaughn hit his 22nd homer of the season off Tomo Ohka (13-8) following Roberto Alomar’s one-out single in the fourth to put the Mets up 3-0.

Rockies 7, Dodgers 1

Denver Denny Stark (10-3) limited Los Angeles to two hits over seven innings, helping Colorado beat the Dodgers.

Shawn Green broke up Stark’s shutout bid, leading off the seventh with his 42nd homer. But that was all the offense the Dodgers could manage.

A crowd of 25,593 was the smallest in the Rockies’ 10-year history.

Phillies 6, Marlins 1

Philadelphia Joe Roa came within three outs of his first career shutout and Jimmy Rollins’ bases-loaded triple sparked a five-run third inning for Philadelphia.

Roa (4-3), who was 14-0 with a 1.86 ERA in Triple-A after being released by the Marlins in spring training, gave up eight hits and walked none in eight-plus innings.

Michael Tejera (8-8) had his shortest outing of the year, giving up six runs.
