Ken Griffey hit two three-run home runs, and Griffey, Don Baylor and Mike Pagliarulo homered in a six-run third inning as the New York Yankees routed the Minnesota Twins, 14-2, for a doubleheader sweep yesterday.

The Yankees won the opener, 3-2, when Dave Winfield led off the 11th inning with his 10th home run. At Yankee Stadium this season, New York is 6-0 against Minnesota and 18-2 against AL West teams.

Rich Bordi (2-2) relieved Bob Shirley in the second inning of the second game and retired all 14 batters he faced.

Griffey's three-run homer off Rick Lysander (0-2) gave the Yankees a 4-2 lead. One out later, Lysander, in his first start since Sept. 5, 1983, yielded a single to Winfield and was replaced by Pete Filson. Filson got one out before Baylor hit his 14th home run and Pagliarulo followed with his sixth.

"I really think it was contagious," said Pagliarulo. "Everybody was ripping the ball after Winnie's homer (in the opener). You feel when one guy does it, you can do it."

The errorless streak of the Yankees' Don Mattingly ended at 153 games -- 25 short of Mike Hegan's American League record for a first baseman and 40 shy of Steve Garvey's major league mark -- when he bobbled a ground ball in the opener.
