Marcus Stroman insisted in February that he is a starter, not a relief pitcher, and thanks to injuries in the rotation he got his chance early this Yankees’ season.

Now it is unclear how much longer he will stay in that role.

On a cold, rainy Friday night at Yankee Stadium, the Giants knocked Stroman out of the game after he had recorded only two outs and allowed five runs and four hits, walking three.

It would be difficult to imagine a worse performance for Stroman, who threw 46 pitches in the first inning, which began after a nearly 30-minute rain delay.

Stroman, who entered the game with a 7.27 ERA, left at 11.57.

Mike Yastrzemski led off the game with a double, Willy Adames walked and Jung Hoo Lee homered to rightfield to make it 3-0 after three batters.

Then Matt Chapman and Heliot Ramos walked and LaMonte Wade Jr. doubled them in to make it 5-0. Stroman finally recorded two outs, then allowed a single to Tyler Fitzgerald to load the bases.

Ryan Yarbrough relieved Stroman and ended things by striking out Yastrzemski.

Before the game, there were a couple of positive ways of looking at Stroman’s unsightly stats after two starts.

First, the Yankees won both games comfortably — 12-3 over the Brewers and 10-4 over the Pirates — despite him allowing seven runs, eight hits and four walks in 8 2/3 innings.

Second, manager Aaron Boone insisted that he had seen good things from Stroman, the righthander out of Patchogue-Medford High School, who turns 34 on May 1.

“Mostly good,” Boone said 3 ½ hours before Stroman’s first pitch. “I feel like especially as the back end of spring training unfolded, the movement quality really started to get to where he wanted them, meaning the bite on the sinker, the movement on the cutter that I feel like’s been really good here these first couple of starts.

“Been a lot of good in those starts. Especially his first start he gave up the homer down the line, which kind of changed the [statistics] line a little bit. But otherwise, I thought he was pretty sharp overall. He was kind of cruising until that fourth inning in his last start as well.

“So for him, obviously not being overpowering, it’s making sure his movement is where he needs it and then in the strike zone enough. He’s going to work the edges, because he does have command, but it’s making sure he’s in the strike zone enough to where the walks don’t come back to hurt him.”

The Yankees looked to trade Stroman in the offseason because of an apparent surplus of starting pitchers, but that surplus is no more.

So having him pitch relatively well — and for enough innings — would have been a boost with Gerrit Cole gone for the year and Luis Gil out until at least midsummer.

Stroman, whom the Yankees will pay $18.3 million this season, arrived at spring training (two days after the other pitchers) declaring, “I’m a starter. See how it plays out. I’m a starter. I won’t pitch in the bullpen. I’m a starter.”

Stroman had an uneven 2024, his first season with the Yankees.

In his first 14 starts, he went 6-2 with a 2.82 ERA. In his next 15 starts, he went 4-7 with a 6.00 ERA in 72 innings.

General manager Brian Cashman said in February of Stroman’s “I’m a starter” remark, “That’s vintage Stro. He’s a competitor. And I agree with him, he is a starter. So let’s just see how everything plays out.”

Notes & quotes: Friday was the 64th anniversary of the major-league debut of Yastrzemski’s grandfather, Carl, who is from Bridgehampton . . . Clarke Schmidt made his second rehab start on Thursday, throwing four scoreless innings with four strikeouts, no walks and four hits allowed for Double-A Somerset. “I thought he was sharp,” Boone said. “Good, strong four innings, 61 pitches, so we’ll probably insert him [into the rotation] now, in five or six days. But that being said, I haven’t even seen him yet. I want to get through [Friday] with the weather and see where we’re at.”
