SEATTLE (AP) _ A brief stint in the bullpen evidently has gotten Seattle pitcher Mike Morgan back on track.

After getting shelled in his first three starts and being demoted to the bullpen, Morgan, 2-3, won his second straight game after returning to the starting rotation to lead the Mariners to a 7-3 victory over the Milwaukee Brewers Sunday.

''He pitched a hell of a ballgame,'' Mariners Manager Dick Williams said. ''His last two outings have been great.''

Morgan pitched his first complete game of the year, allowing eight hits.

''He's a good competitor,'' Milwaukee Manager Tom Trebelhorn said of Morgan. ''He got off to a rocky start this year, but it looks like he's on track now.''

The Mariners struck early, scoring six runs in the first three innings off Brewers starter and loser Teddy Higuera, 4-1.

''I've seen him get off to shaky starts before, then come back, but not today,'' Trebelhorn said.

The Brewers made a run at Seattle, scoring twice in the fifth and once in the sixth. But Morgan pitched hitless ball over the last three innings.

''I still had the lead,'' Morgan said. ''I wasn't going to let them come back.''

The Mariners scored twice in the first inning on RBI singles by John Christensen and Alvin Davis and added three more runs in the third on run- scoring doubles by Davis and Rey Quinones, and a sacrifice fly by Dave Valle.

It was career victory No. 1,481 for Williams, who passed Earl Weaver on the all-time list for 14th place.

''That means I've been around a long time,'' Williams said.
