SEATTLE – Here was the gospel according to Earl Weaver showing Monday night that his words remain still true today: Pitching, defense and the three-run homer is a heck of a winning formula.

The Mariners got a pair of three-run homers in their 7-5 victory over the New York Yankees at Safeco Field. Their vaunted bullpen also bounced back after Sunday’s hiccup loss to Milwaukee.

And there was defense.

The Mariners erased a pair of two-run deficits by getting a three-run homer in the fourth inning from Kyle Seager and another in the sixth from Mike Zunino.

Their bullpen produced 3 1/3 scoreless innings after Cody Martin surrendered five runs on four homers – two apiece from Gary Sanchez and Starlin Castro.

Defense?

Right fielder Shawn O’Malley made a diving catch into the stands for the second out in the seventh inning. And second baseman Robinson Cano made a long run later in the inning to track down a Jacoby Ellsbury pop.

Nick Vincent, Vidal Nuno, Steve Cishek and Edwin Diaz provided the bullpen relay. Vincent (3-3) got the victory. Cishek retired Sanchez and Castro while protecting a one-run lead in the eighth inning.

After a Nelson Cruz homer provided a two-run cushion, Diaz worked around a shaky start to the ninth inning in closing out the victory for his 10th save in 10 chances.

The Mariners climbed back to a season-best 10 games over .500 at 67-57 and remained one game behind Baltimore in the race for the American League’s final wild-card berth.

The Mariners trailed 5-3 when they knocked out ex-Mariner Michael Pineda in the sixth inning by putting two runners on base with one out.

New York manager Joe Girardi played match-ups and won the first one when lefty Tommy Layne retired Adam Lind on a pop to second. Girardi then summoned righty Anthony Swarzak to face Zunino.

On a full count, Swarzak (1-2) threw a slider the Zunino reached out and drove 366 feet to right for a three-run homer.

The Mariners led 6-5.

Sanchez marked his first at-bat since being selected earlier Monday as the American League player of the week by lining a two-out homer to left in the first inning.

Castro’s leadoff homer in the second extended New York’s lead to 2-0.

A double-play grounder enabled Martin to work around a one-out walk in the third inning, but the Yankees started the fourth with singles by Sanchez and Didi Gregorius. A strikeout and a double play kept it at 2-0.

That allowed the Mariners to grab the lead on Seager’s three-run homer in the bottom of the inning – a 403-foot drive to center field on a 3-0 count. It was Seager’s 24th homer of the year.

That lead lasted until Sanchez’s next at-bat, which came with one on and one out in the sixth. He crushed an 88-mph fastball from Martin for a two-run homer to center.

Castro’s second homer, a two-out drive later in the inning, reestablished New York’s two-run lead at 5-3. When Martin then walked Brian McCann, manager Scott Servais went to the bullpen for Vincent.

Play of the game: Right fielder Shawn O’Malley, just inserted for defensive purposes, made a leaping catch into the stands on Tyler Austin’s one-out high foul in the seventh inning.

O’Malley had to push past a fan to make the catch. He held the ball-in-glove aloft as, twisting, he fell backward into the seats.

First-base umpire Jeff Nelson, the crew chief, went down the line and verified the catch for the out.

O’Malley’s catch overshadowed a fine running catch later in the inning by second baseman Robinson Cano into right field on Jacoby Ellsbury’s pop for the final out.

Stat pack: With two homers and a single, Gary Sanchez (54) became only the second Yankees player in history to reach 50-plus total bases in his first 19 games. The other is Joe DiMaggio (56).
