Jordany Valdespin could use a cup to runneth over.

The Mets utilityman exited yesterday’s exhibition game against the Tigers after he was hit in the genitals with a Justin Verlander 94-mph fastball, and left club officials shaking their heads by revealing he wasn’t wearing a protective cup.

“You would think if you are starting at second base, you would be smart enough to wear a cup,” manager Terry Collins fumed to The Post after the Mets’ 11-0 victory at Joker Marchant Stadium.

Valdespin, who homered leading off the game facing Verlander, was attempting a bunt in the fifth inning against the stud fireballer when he was struck, crumpling him to the ground in agony.

Asked where the pitch hit him, Valdespin replied, “in the d--k,” adding that everything is “fine” and he doesn’t expect to miss action.

“Everything is good, working good, normally, everything is great,” Valdespin said.

The flamboyant 25-year-old departed the ballpark before it was revealed to The Post he wasn’t wearing a cup. But it wasn’t that Valdespin got hit in the sensitive area without a cup that miffed Collins as much as the player showing a probable lapse in judgment by shunning the protection on a day he was playing second base. One former major league infielder said it’s “highly unusual” for a second baseman not to wear a cup.

“If you are playing the infield, it is part of the uniform,” the former infielder said.

Valdespin’s penchant for flying open early on bunt attempts leaves him vulnerable, said one Mets instructor.

Verlander, a former MVP and Cy Young Award winner, said it was the first time he had drilled a batter in that spot.
