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. 

With Giancarlo Stanton leading the way with his second home run in as many nights and a four-RBI game, 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. 

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 (tying a career-high) and holding the Rockies (35-58) to just three hits and one walk. 

Schmidt has now posted a 2.86 ERA over his past 10 starts, providing the Yankees some much-needed consistency. 

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

Gleyber Torres (2-for-4, 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. 

Stanton has now hit four home runs in his past four games, including blasting homers in back-to-back games for the first time since April 1-2. 

“He’s getting there,” manager Aaron Boone said before the game. “It’s timing, it’s rhythm, it’s that subtle load that he has within his legs and how his hands [move], so he’s getting in that good position to make a good swing decision. He’s getting there. He’s not to that point where when ‘G’ really locks it in, then you’re in real trouble.

“But there’s no question the last couple weeks he’s trending in that direction.” 

One area of concern for the Yankees was Josh Donaldson, who came up limping on a groundout in the seventh inning, appearing to tweak something in his leg.

He jogged off the field gingerly, but since he was serving as DH and his spot did not come up again the rest of the game, the extent of the physical issue was not immediately clear. 

Stanton drove in the Yankees’ first run of the night on a groundout in the first inning, scoring Torres, who had tripled on the first pitch of the game. 

The Yankees then jumped on Rockies right-hander Connor Seabold for five runs in the second.

Seabold entered the game with a 6.65 ERA, but that hasn’t meant much for the Yankees lately.

Just within the past week-plus, they had been one-hit across eight innings by Jameson Taillon (who entered the game with a 6.93 ERA) then on Friday were stifled by Rockies left-hander Austin Gomber. 

LeMahieu got the rally started with his first double of the night, this one 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 jumped on Seabold’s fastball down the middle and roped it to right field for a three-run shot that made it 6-1. 

Schmidt gave up a run in the first inning by balking in a runner from third base — the Yankees’ MLB-leading 11th balk of the season — before settling in. 

Entering the seventh inning, Schmidt had retired 16 of 18 hitters.

But C.J. Cron ended his night on a sour note, crushing a home run to center field to knock Schmidt out of the game. 

The Rockies added a run in the eighth inning off Tommy Kahnle, marking the first run he has given up this season after entering the night with 15 ¹/₃ scoreless innings.
