Shohei Ohtani got booed by a road crowd Monday night — for hitting a single instead of a double, when he needed the latter to complete the cycle.

Or maybe they were booing Austin Hays, wondering why he fielded the ball quickly and didn’t let Ohtani get to second.

Either way, according to the Baltimore Banner and ESPN, the Camden Yards crowd of about 20,000 started booing when the Angels star — and starting pitcher — converted his fourth hit of the night against the Orioles.

“Yeah, I was aware of it,” Ohtani said about being a double away from the cycle, through a translator during a Bally Sports West postgame interview. “Not just that at-bat, but the at-bat before, I was aware I was a double shy.”

He finished 4-for-5 with a walk, and according to the Baltimore Banner, Ohtani became the first pitcher to reach safely five times in a game since 1964.

According to The Post’s Jon Heyman, Ohtani would’ve become the first player to hit for the cycle in the same game he was also the starting pitcher.

Ohtani threw seven innings, allowing all five Baltimore runs while striking out five batters and walking two, and in a postgame interview on Bally Sports West, Ohtani wasn’t thrilled about the homer he allowed in the third inning that gave the Orioles a temporary lead.

At the plate, he started the night by walking against Orioles starter Grayson Rodriguez, but then Ohtani lined a single in the third inning for his first hit.

In the next inning, with runners on first and second, Ohtani crushed an 80 mph curveball 456 feet for a home run that gave the Angels the lead for good.

He followed that with his third hit in as many innings in the fifth, blasting a triple. 

That gave him two at-bats to record the double that gave him the cycle, but he grounded into a fielder’s choice before sticking his bat over the plate and lofting a single — his softest hit of the night, according to Statcast, with an 84.1 mph exit velocity — into left field.

Hays played the ball on one hop, and as Ohtani rounded first, the Camden Yards crowd started booing.

“I wasn’t dying to try to hit that double,” Ohtani told Bally Sports West. “I was just trying to make solid contact and let the ball do its thing.”

The Angels defeated the Orioles, 9-5, to move to 22-20 this season.
