GOT LANCED

Lynn pierced by four-run 1st inning

Lance Lynn delivered everything the Yankees could have asked for in his first three appearances after arriving from Minnesota, giving up just one run in 16 2/3 innings.

Then came the first inning Friday night.

In a rain-shortened 7-5, seveninning win over the Blue Jays in The Bronx, the big righty allowed four first-inning runs. Even after the Yankees took the lead with Neil Walker’s threerun homer in the fourth, Lynn gave it right back by allowing a run in the fifth.

“When you’re not in attackmode early on and walking people, that’s how things go for you,’’ Lynn said. “The offense came back and bailed me out.”

It was the first rough patch for Lynn as a Yankee after he arrived from the Twins with a 5.10 ERA in 20 appearances.

“It was frustrating,’’ said Lynn, who allowed five runs in four-plus innings. “Next time I’m gonna be better. The first was ugly. I’ll make sure it doesn’t happen again.”

Lynn said the rain that fell for part of the first inning may have played a role in his early woes.

“It was a little bit of everything,’’ Lynn said. “I just wasn’t good and I’ve got to be better.”

He also pointed to a close 3-2 pitch to Randal Grichuk that was called ball four to extend the inning, which allowed Aledmys Diaz to hit a two-run single to center.

“I was one pitch away from just giving up one or two and all of a sudden it’s four,’’ Lynn said.

There was also an oppositefield single by Kendrys Morales — who entered the game 3for-4 with a pair of homers in his career against Lynn — and a fly to shallow right by Kevin Pillar that fell in front of Neil Walker for an RBI single.

But there were also two walks and a wild pitch against a Toronto lineup that had tagged him for six runs in five innings in an April 30 start when he was still with Minnesota.

Booed in The Bronx for the first time since joining the team, Lynn rebounded to whiff Richard Urena to finally end the frame — but he had thrown 37 pitches.

Lynn settled in to retire nine of the next 10 batters. But then Curtis Granderson doubled and Devon Travis singled him in to open the fifth, and Lynn was yanked.

Aaron Boone at least liked the way Lynn kept the Yankees in the game.

“I loved that after throwing 30-something pitches [in the first], he doesn’t flinch,’’ Boone said.

Chad Green prevented further damage and the Yankees retook the lead in the bottom of the fifth inning.
