SEATTLE (AP) _ Clint Nageotte pitched six shutout innings in his first major league start, leading the Seattle Mariners to a 5-0 win over the Houston Astros on Monday night.

Nageotte (1-1) was a top Mariners prospect last year after leading the Double-A Texas League with 157 strikeouts. He was solid all night, allowing six hits with eight strikeouts and three walks.

Scott Spiezio had a solo homer, two singles and two RBIs as the Mariners scored three runs off starter Brandon Duckworth (1-1) in only one-third of an inning, the shortest outing of his career. Seattle had 11 hits and won its third straight.

Houston's Jeff Kent singled in the fifth, extending his career-high hitting streak to 22 games. That matched Carlos Lee of the Chicago White Sox for the longest current streak in the majors.

Nageotte was called up from the minors May 28 and his start broke up Seattle's regular rotation for the first time since Ismael Valdes pitched for the Mariners on Sept. 29, 2002.

Last year, Seattle became the first team since the 1966 Dodgers to use only five starters. Meche was joined by Jamie Moyer, Joel Pineiro, Freddy Garcia and Ryan Franklin.

Nageotte gave up a single to Craig Biggio leading off the game. But he settled in after that, using a 92 mph fastball and a tricky, big-breaking curve to keep the Astros in check.

The rookie faced a jam in the third. He got Biggio swinging with two runners on base, then got a groundout by Adam Everett, and loaded the bases with a two-out walk to Jeff Bagwell.

Nageotte stayed cool and struck out Kent on a breaking ball. Kent was so frustrated that he stepped out of the batter's box and threw his bat into the netting near the Houston dugout.

Julio Mateo pitched three scoreless innings for his first save.

Seattle led 3-0 early, using RBI singles by John Olerud, Bret Boone and Spiezio to chase Duckworth.

It was 4-0 in the third after Rich Aurilia's RBI double scored Jolbert Cabrera, who was running from first after reaching on a fielder's choice. Spiezio made it 5-0 in the fifth, lining a shot to right field off reliever Pete Munro.

Mariners RF Ichiro Suzuki extended his hitting streak to 14 games with a second-inning single. He robbed Houston LF Lance Berkman with a sliding catch in right in the second. ... The crowd of 28,556 pushed Seattle over 1 million fans for the season, the third AL team to reach the mark behind New York and Anaheim.
