DENVER — Whether it was a sign of things to come, the Sean Casey effect kicking in, beating up on a bad pitcher, the high altitude or just one good night, the Yankees will gladly take it. 

Giancarlo Stanton led the way with his second home run in as many nights and a four-RBI game, and the Yankees cruised to a 6-3 win over the Rockies on Saturday night at Coors Field. 

The Yankees (50-43) used a five-run second inning to blow the game open, keyed by Stanton’s three-run homer to the opposite field. 

“I’m putting good at-bats together, so as long as I stay on time and keep my rhythm, I can keep this going,” said Stanton, who has hit four home runs in his last four games and has crushed homers in back-to-back games for the first time since April 1-2. 

That was enough offensive support for Clarke Schmidt, who turned in another strong start.

He pitched into the seventh inning for the first time in his big league career, finishing with six-plus innings of two-run ball while striking out eight to tie a career-high.

He held the Rockies (35-58) to just three hits and one walk. 

With the win, only their second in their last seven games, the Yankees snapped out of a last-place tie in the AL East with the Red Sox. 

Gleyber Torres (2-for-5, triple) and DJ LeMahieu (3-for-4, two doubles) also delivered multi-hit games for the second straight night, but this time, they got some help from more than just Stanton. 

“We’re capable, they’re grinding, and a lot of these guys are going to get hot together,” manager Aaron Boone said. “That’s when the fun happens.” 

Boone said before the game that he thought Stanton was close to going on one of his patented hot streaks.

Then, after he had driven Torres homr on a groundout in his first at-bat, Stanton came up in the second and jumped on a fastball down the middle, sending it the other way for a three-run homer.

The blast accounted for Stanton’s 1,000th career RBI and put the Yankees up 6-1. 

“Definitely trending [in the right direction],” Stanton said. “You gotta prove that you’re all the way going, and that’s with weeks on end of producing. So yeah, there’s not much talking for that. You gotta go prove it.” 

The Yankees took advantage of Rockies right-handed starter Connor Seabold, who entered the game with a 6.65 ERA — though inflated stats for opposing pitchers haven’t meant much for the Yankees lately.

Just within the last week-plus, they had been one-hit across eight innings by Jameson Taillon, who entered the game with a 6.93 ERA, and then stifled Friday by Rockies left-hander Austin Gomber, who had a 6.40 ERA coming in. 

On Saturday, LeMahieu got the second-inning rally started with his first double of the night, with some help from a poor read by right fielder Nolan Jones.

One out later, Harrison Bader hit a bloop single and Anthony Volpe walked to load the bases for Kyle Higashioka, who delivered a sacrifice fly to put the Yankees back on top, 2-1. 

Torres then came through with an RBI single before Stanton’s blast. 

“He’s definitely swinging better,” Boone said of Stanton. “We’ve all seen him dialed in, so I don’t want to go and say he’s there, because that’s a different level. But I feel like the last week, 10 days, two weeks, definitely continues to move in the right direction.” 

Stanton, Torres and LeMahieu have combined to go 13-for-24 through the first two games of this series, offering hope that they can lead a much-needed offensive turnaround for the Yankees in the second half. 

“When [Stanton] starts going, it’s impressive to watch,” Schmidt said. “You can tell his at-bats have just gotten a lot better, seeing the ball a lot more, deeper counts and a lot less swing and miss. It’s going to be good for our offense to watch him go on a run.”
