NEW YORK (AP) - Aaron Judge and Miguel Andujar hit two-run homers off James Paxton in the first inning that sent the New York Yankees over the Seattle Mariners 4-3 Thursday for a three-game sweep.

Luis Severino and the Yankees boosted the best record in the majors to 50-22. They've won four in a row and 17 of 21. Seattle has lost a season-high four straight.

New York launched eight homers in the sweep and tops baseball with 122 long balls. Giancarlo Stanton homered in the first two games of the series and almost added another, but center fielder Mitch Haniger jumped to reach above the wall to rob him in the opening inning.

Severino (11-2) wasn't at his best. He gave up Kyle Seager's two-run homer in the second and permitted eight hits overall, matching a season most. He was pulled with two outs in the sixth after Ben Gamel's RBI single cut Seattle's deficit to one run.

Severino improved to 7-0 at home this season. David Robertson and Dellin Betances protected the lead, and Aroldis Chapman struck out Dee Gordon on three pitches with a runner on second for his 22nd save in 23 chances,

Paxton (6-2) vigorously pawed at the dirt in front of the rubber for a full 15 seconds before throwing his first warmup pitch. Coming off his shortest start of the year against Boston, he never got settled in his first career start facing the Yankees.

Clint Frazier led off with a single and Judge followed with his 19th homer. Gleyber Torres singled with two outs and Andujar sliced a flyball to right field that landed in the short porch for the rookie's 10th home run.

Paxton drifted a few steps onto the grass as the ball flew and gazed toward center field when it left the park. Andujar was among several New York hitters who successfully went the opposite way against the big lefty.

Paxton had been 5-0 in 10 starts since April, including a no-hitter at Toronto. He went five innings and threw 107 pitches, the same total as Severino.

The first day of summer brought a sellout crowd that included a bunch of camp kids who cheered most every flyball. Also in attendance was an older Boy of Summer - 90-year-old Tommy Lasorda watched from a box, along with Kentucky coach John Calipari and Dallas Cowboys coach Jason Garrett.

TRAINER'S ROOM

Mariners: OF Guillermo Heredia again was out of the starting lineup. He's in an 0-for-15 skid, part of a rough June. He pinch ran in the eighth and was caught stealing at second.

Yankees: Put RHP A.J. Cole on the 10-day disabled list because of a left neck strain, a move was retroactive to Wednesday. RHP Luis Cessa was reinstated from the 10-day DL (oblique); he hasn't pitched for the Yankees since April 17.

UP NEXT

Mariners: LHP Wade LeBlanc (3-0, 2.63 ERA) starts at Fenway Park vs. Boston knuckleballer Steven Wright (2-1, 1.23). LeBlanc pitched into the eighth inning against Boston in his last outing, a 1-0 win.

Yankees: LHP CC Sabathia (4-2, 3.30) starts at Tampa Bay. He lost to the Rays in his last start, striking out 10 and giving up 10 hits in 7 2/3 innings.
