Jimenez stellar as Rockies snap losing skid

HOUSTON (Reuters) - The indomitable Ubaldo Jimenez pitched seven scoreless innings on Thursday en route to a Major League-leading eighth win that snapped a three-game losing skid for the Colorado Rockies.

Jimenez, who tossed a no-hitter last month, allowed one hit in his team's 4-0 win over the hapless Houston Astros and lowered his ERA to 0.99, the best for a starter in baseball.

The tough right-hander got early run support when Troy Tulowitzki hit a three-run homer in the first inning.

Brad Hawpe added an RBI single in the eighth for the Rockies (20-21), who used a pair of relievers to close out the final two innings.

The Astros (14-27) lost for the sixth time in seven games despite a solid outing from starting pitcher Roy Oswalt, who struck out eight and allowed two earned runs in six innings.
