Alex Rodriguez explains homering for Trenton, then grabbing right leg

A-Rod talks about his homer in Trenton on Wednesday night ... and what happened during his home run trot. Watch video

TRENTON -- The big crowd at Arm & Hammer Park was on its feet and cheering.

Yankees designated hitter Alex Rodriguez went yard in his second and final at-bat in his second and final rehab game with the Trenton Thunder, then broke into a home run trot that wasn't much of a final test for his right hamstring.

Or was it?

Just after A-Rod rounding second base, he grabbed his right leg while continuing his jog.

"Did you see that?" a local radio reporter called out. "He grabbed his hamstring. He grabbed both of them."

He did indeed.

It was nothing.

It looked like A-Rod simply was adjusting his pant legs and ... 

"You were right," he said. "I was adjusting both of my pants. They were a little big. They were falling."

The pants didn't stop A-Rod from making the most out of his two Class AA Eastern League games. He was 2-for-4 with two singles on hard-hit balls on Tuesday, then 1-for-2 with a two-run, second-inning homer on Wednesday.

A-Rod hits monster homer

This was just a minor-league homer by an all-time great who has 692 for his career, but it still felt great lining a shot out of the ballpark to straight-away center after not playing for three weeks.

"There's no question," said A-Rod, who is expected to come off the disabled list on Thursday and be available to play in the Yankees-Toronto Blue Jays series finale at Yankee Stadium. "Whether you're playing in high school or in the major leagues, a home run feels good. The ball came off the bat nicely. You kind of walk before you run, and that was a good start today."

Counting his four-game rehab stint with the Thunder in 2013, A-Rod's home run total for the franchise now is three. He was jokingly asked afterward if he's thinking the Thunder someday will retire his No. 13.

"They keep stats here, too?" A-Rod said with a laugh. "I thought the pressure was only in New York. ... Look, I really like coming here. Great fan base. I really appreciate the fans coming out and being so supportive. And it's nice to come out and play well."
