SEATTLE (AP) - Doug Fister struck out a career-high seven in 6 1/3 innings, and the light-hitting Seattle Mariners capitalized on 11 walks allowed by Detroit, routing the Tigers 13-3 on Tuesday night.

The Mariners entered as the worst hitting team in the American League with runners in scoring position. That quickly changed thanks to a first-inning outburst kept alive by an error from Detroit starter Phil Coke (1-3), and a two-out, two-strike single from Chris Gimenez that made it 4-0.

The clutch hitting continued in the fourth when Chone Figgins got his first hit all season with a runner in scoring position, driving in Ichiro Suzuki. Seattle added five runs in the seventh off Detroit's bullpen and the 13 runs were a season high.

Fister (1-3) was rolling before he got into trouble in the seventh. He was charged with two runs and five hits, and walked two.

Getting some run support probably felt quite foreign to Fister. Before this start, the right-hander had received just three runs in his three previous starts this season and only two while he was in the game.

Coke started the game with five-pitch and four-pitch walks to Suzuki and Figgins. Milton Bradley then hit a tapper in front of the plate and Coke wasn't able to field the ball cleanly, loading the bases.

Jack Cust forced in a run with a walk and Brendan Ryan picked up an RBI with a one-out bouncer to shortstop. After Coke issued another walk - this one to Jack Wilson - Gimenez lined an 0-2 pitch into left-center for a 4-0 lead.

In its first 17 games, Seattle scored only one run in the first inning.

Seattle went 7 for 22 with runners in scoring position.

Coke lasted just 3 2-3 innings, after throwing seven shutout innings in his last start against Oakland. He gave up six runs, two earned, and walked four, matching his career high.

Enrique Gonzalez, Al Alburquerque and Brad Thomas followed with more of the same, combining to give up seven runs, nine hits and walk another seven batters.

Fister had retired eight straight and 14 of 15 - the only runner reaching on third baseman Figgins' error in the fourth - entering the seventh. Miguel Cabrera, Brennan Boesch and Ryan Raburn reached on three straight singles and, after a popout by Jhonny Peralta, Alex Avila walked on a close 3-2 pitch to force in a run and end Fister's night.

Jamey Wright took over and got Brandon Inge to ground into a double play on his first pitch.

Fister, who threw a career-high 110 pitches, lasted at least six innings for the third straight start. He started the game with consecutive strikeouts of Austin Jackson and Will Rhymes, both looking, then was the first to greet Wright at the dugout steps after his one-pitch double play to end the seventh.
