DETROIT (AP) -- Kevin Slowey pitched seven shutout innings and Mike Lamb homered as the Minnesota Twins beat the Detroit Tigers 9-4 Friday night.
Dontrelle Willis returned from a stint on the disabled list with a knee injury to toss an inning of relief for the Tigers, but otherwise it was another woeful night for one of the majors' most disappointing teams.
Last-place Detroit (20-28) scored 30 runs in a three-game sweep of Seattle, but Slowey (1-4) pushed them back into a slump. The Tigers had scored 14 runs in their previous seven games before clobbering the Mariners.
Slowey gave up four hits and three walks in six innings for his first win since Sept. 23.
Detroit's Armando Galarraga (3-2) struggled with his control for the second straight start, walking five batters while giving up five runs in six innings.
Willis replaced Galarraga in his first appearance since April 11. He allowed one run on a hit and two walks in one-plus innings.
Galarraga escaped after walking two in the first, but the Twins scored three in the second.
Two singles and a walk loaded the bases with no one out, and Brendan Harris hit an RBI groundout before Carlos Gomez and Joe Mauer added RBI singles.
Michael Cuddyer's run-scoring single put the Twins ahead 4-0 in the fifth before Lamb hit his first homer in the sixth.
Detroit had its best chance in the sixth, putting runners on second and third with two out, but Carlos Guillen grounded out.
As the Tigers took the field for the seventh, Tigers manager Jim Leyland got into an animated argument with third-base umpire Hunter Wendelstedt, apparently about a called strike on Guillen, and was ejected.
Ivan Rodriguez's two-run triple off Dennys Reyes made it 5-2 in the seventh, and Marcus Thames added an RBI double, but was out after sliding past the base.
That cost the Tigers a run when Gary Sheffield homered two batters later, but the Twins minimized the damage by scoring three runs in the eighth on Harris' RBI single and a two-run double by Justin Morneau.
