Pittsburgh Pirates starter Zach Duke pitches in the fourth inning of the baseball game against the Colorado Rockies in Pittsburgh, Sunday, May 17, 2009. Duke got the win as the Pirates rallied from a 4-1 deficit to win 11-4.

PITTSBURGH — The Colorado Rockies had a bottom of the seventh inning they'd like to forget. The Pittsburgh Pirates enjoyed it so much, they probably wish it was still going.

Nate McLouth had three of his four RBIs during a 10-run seventh inning, and the Pirates came from behind to take their second straight from the Rockies, 11-4 on Sunday.

The first 11 batters reached in the seventh for Pittsburgh, which trailed 4-1 entering the inning but scored at least 10 runs in an inning for the first time since Aug. 20, 2003.

"You don't see 10s on the board too often," Rockies manager Clint Hurdle said. "Everything just kind of broke loose."

The inning featured nine hits, two Rockies errors — three balls bounced off Colorado outfielders' gloves — and a reliever who earned a trip to the disabled list when he happened to step on a bat while running to back up home plate.

"Things were going our way that inning," McLouth said, "and sometimes you need that to have an inning like that."

McLouth also homered for the second consecutive game, and Andy LaRoche had two hits and two RBIs for the Pirates, who have won four of their past six since snapping an eight-game skid.

The Rockies' Ubaldo Jimenez allowed only one run for the third straight start, but he could not extend his personal winning streak to three when the bullpen — and the Colorado defense — didn't hold a three-run lead for him.

"It is hard, not for me not getting the win — it was hard for the team," said Jimenez, who allowed five hits and three walks while striking out seven in six innings. "We were looking for the win to win the series, but it didn't work out."

The wild seventh inning started when Matt Daley walked pinch hitter Eric Hinske. Delwyn Young followed with a single to left, and Freddy Sanchez snapped an 0-for-13 stretch with an RBI double off Brad Hawpe's glove in right.

Daley was forced to leave the game when he sprained his left foot after Sanchez's hit. As he was running past home plate, umpire Bill Welke tossed the bat aside to clear the area, and the bat happened to land just underneath Daley's next stride.

"It was just a freak accident," Daley said.
