The past week has taught Will Warren a valuable lesson about the ebbs and flows of a 162-game season.

Last Wednesday, the Yankees rookie gave up eight runs to the Blue Jays in four innings, including seven in the first, as his team suffered a crushing loss at Rogers Centre in Toronto.

Seven days later, he was terrific in the Yankees’ 10-3 win over the Mariners on Tuesday in The Bronx, tossing 5 ²/₃ scoreless innings with four strikeouts.

“I think you can take every outing and learn from it, good or bad,” Warren said after Tuesday’s game. “Obviously, the bad ones hurt a little more. You can take a little more from those.”

Whatever he took from his struggles in the Yankees’ 11-9 loss to the Blue Jays paid off against Seattle.

Warren gave the Yankees a smooth outing against a dangerous Mariners lineup headlined by powerful switch-hitting catcher Cal Raleigh and rising star Julio Rodríguez.

Raleigh, who is on pace to break Aaron Judge’s American League single-season home run record with 64, tapped a pair of soft groundouts and drew a walk against Warren — before crushing a two-run blast, his 36th of the season, off Geoff Hartlieb in the eighth.

Rodríguez grounded out twice and struck out against Warren.

“He set a great tone,” Yankees manager Aaron Boone said of Warren. “Strike throwing was good. He was filling up the zone, which was good to see, and thought he was sharp.”

After giving up a leadoff single to Mariners shortstop J.P. Crawford, Warren retired the next seven batters he faced to set the tone for his outing.

The 26-year-old gave up a pair of singles in the fifth to set up runners at the corners with two outs, but — after a 35-minute rain delay — he induced a groundout from Crawford to escape the threat before getting two more outs in the sixth.

That was enough to outdo Mariners starter Logan Gilbert, who was perfect through the better part of four innings before getting shelled for five earned runs in the sixth.

“Just attacking the zone,” Warren said of his approach. “Attacking the zone early, executing pitches and good things happen.”

With Gerrit Cole out for the year, Ryan Yarbrough (oblique) and Luis Gil (lat) on the 60-day IL and Clarke Schmidt likely out for a prolonged period, Warren has emerged as a stabilizing force in the Yankees rotation with a 4.70 ERA and 11 strikeouts on the season.

Boone added that Warren’s sinker, in particular, stood out.

“The depth on some of his sinkers tonight, from the side, was like, ‘Woah,’ ” he said.

Warren said he was “leaning heavily” on that pitch Tuesday night.

“I have confidence in it every outing,” Warren said. “Today, it was nice to get a bunch of ground balls with it, especially with a lot of traffic on.”
