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) gave up two runs and five hits.
The teams wrap up their three-game set Wednesday in Seattle at 3:40 p.m.
