Happ arrives not a moment too soon

J.A. Happ finally arrived in The Bronx on Saturday — and not a minute too soon.

The lefty, whose flight from Chicago was cancelled on Friday, got to Yankee Stadium on Saturday and will make his first start for his new team Sunday — after watching another less-than-stellar outing from Luis Severino.

He’ll make his debut against the Royals, but what really intrigued the Yankees about the 35-year-old was his ability to pitch well in the AL East — especially against the Red Sox.

Happ is in line to start in Fenway Park when the Yankees go to Boston next week after being traded from the Blue Jays in exchange for Brandon Drury and minor league outfielder Billy McKinney.

Despite going 7-4 with a 2.98 ERA versus the Red Sox in his career, Happ declined to analyze what went into compiling those numbers.

“I don’t think I could answer that,’’ Happ said Saturday. “I don’t think I should even start because I want it to continue. I don’t know. They’re a juggernaut, as well, this year. It’s always a challenge.”

Happ joins a rotation in a bit of flux, as Severino’s struggles continued in a 10-5 loss to the Royals in the first game of Saturday’s split doubleheader.

The need for another arm was evident and the Yankees are pinning their hopes on Happ, even though he hasn’t been at his best lately, either.

In his past six starts with the Blue Jays, Happ was 2-3 with a 6.03 ERA. He gave up 36 hits, 10 walks and seven homers in 31 ¹/3 innings during that stretch.

“I think the results haven’t been there, but there’s no physical issue,’’ Happ said. “For me, it’s always been about being aggressive. If I get in trouble, it’s when I put guys on base with free passes. That’s usually a big indicator.”

He admitted to being anxious about the trade deadline.

“I definitely was,’’ Happ said. “I thought there’d be a good chance I’d be moved, I just didn’t know where.”

And regardless of his recent performance, Happ remains confident he’ll be able to navigate the AL East again — this time with the Yankees.

“I like to compete and there’s probably no better stage to do it [on],’’ Happ said of coming to The Bronx. “Just being in the division five of the last six years, you’ve got to learn to survive. For the most part, I’ve been able to do that. You’re not gonna last very long unless you find a way through it.”
