Domingo German wasn’t perfect, but he was nearly unhittable.

Let’s call it “one-hittable.”

In his second start since throwing the 24th perfect game in MLB history, German allowed one hit and three walks over six innings but had nothing to show for it after the Yankees’ defense and bullpen imploded in a 7-4 loss to the Cubs on an otherwise gloomy Sunday to end the first half of the season.

German faced the minimum number of batters over four innings — thanks to a walk-erasing double play — and was almost halfway to becoming the sixth pitcher with two no-hitters in the same season as the fifth began.

“I knew what was going on,” German said through a translator, “but you have to stay focused on what you are doing out there and not lose your rhythm.”

Seiya Suzuki quickly ended thoughts of history with a leadoff home run that tied the score at 1-1, but German was unfazed in going back to his aggressive approach.

“Attacking hitters from the start, especially first pitch, getting ahead [in the count] early,” German said. “Using secondary [pitches] and expanding [the strike zone] in certain situations was key today.”

The Yankees led 4-1 in the seventh but German was not afforded a rematch against Suzuki.

Manager Aaron Boone controversially pulled German after he issued a leadoff walk on just his 74th pitch, with Suzuki stepping back into the box.

“I just felt like it was time, and we were lined up [with top relievers] there,” Boone said. “Understandable to question the decision, but Domingo coming off a perfect game — last time being a little bit fatigued — obviously threw the ball great. I wanted to get him out of there on a real high note heading into the half.”

German threw at least 80 pitches in 11 of his previous 13 starts, including 86 the last time through the rotation when he followed up perfection by getting knocked around by the Orioles.

He had not thrown fewer than 80 while pitching more than 3 ¹/₃ innings since April 15, so, yes, he felt he had more in the tank.

“Of course,” German said. “I’m healthy and ready to pitch in games like this. It comes down to Boone making a decision.”

German walked off the mound to a rousing ovation from fans — still appreciative of the perfect game on the road — and pointed to his family in the stands.

“It feels great when you get a positive reaction from the fans like that,” German said, “and the respect is mutual.”

The good vibes vanished when the bullpen promptly allowed three unearned runs to tie the score before the seventh was over and three more over the final two innings.
