Bartolo Colon, working on another strong start in a rebound season full of them, pulled up lame while covering first base. After the Yankees finished off their 4-0 win yesterday against the Cleveland Indians, Colon was at a hospital, getting an MRI on his strained left hamstring.

“It’s not what you want, that’s for sure,’’ Yankees manager Joe Girardi said. “He’s pitched extremely well, and we’ll kind of keep our fingers crossed.’’

Alex Rodriguez got hit by a pitch after he homered, and Curtis Granderson and Mark Teixeira also went deep.

Colon struck out six and gave up only two hits against his first major league team before he had to come out on Shin-Soo Choo’s grounder to first.

Colon (5-3), famously traded in 2002 by the Indians for three minor leaguers who went on to become All-Stars, struck out six over 6 2/3 innings to win for the third straight start after two losses in his previous five.

The Yankees, who have already lost starter Phil Hughes to a shoulder injury, will have to wait and hope for the best with Colon, who has been a key starter for them this season. He lowered his ERA to 3.10, best in the rotation.

“Bartolo is throwing like a legit No. 1 starter in the AL East,’’ Rodriguez said.

A-Rod was in the middle of the action. He was hit by a pitch after he homered the previous time up, and shortly after Granderson hit his 20th of the season. The two sluggers both homered against Cleveland the night before.

Plate umpire Dan Iassogna immediately tossed Mitch Talbot after the righty hit Rodriguez. Talbot said he told Iassogna that he slipped while throwing the pitch.
