SEATTLE (AP) _ Bill Swift and two relievers combined on a nine-hit shutout as the Seattle Mariners snapped a four-game losing streak with a 4-0 victory over Los Angeles in interleague play Friday night.

Swift (5-3) left with the bases loaded and one out in the seventh, but Mike Timlin got out of the jam by striking out Jose Vizcaino and getting Gary Sheffield to ground out. Heathcliff Slocumb pitched the ninth.

The Mariners took a 2-0 lead off Ismael Valdes (4-7) in the second on RBI singles by Glenallen Hill and Dan Wilson. The first run was unearned because David Segui got aboard on third baseman Bobby Bonilla's fielding error.

In the fifth, the Mariners made it 3-0 on Joey Cora's triple and Alex Rodriguez's groundout. They added a run in the sixth when Rob Ducey, who doubled, scored from third on Dan Wilson's suicide squeeze single.

Swift, who allowed nine hits and walked one in 6 1-3 innings, got his third straight victory, while Valdes lost for the third time in four decisions.

Valdez allowed nine hits and four runs in 7 1-3 innings.
