Ivan ‘Pudge’ Rodriguez Strips Down To His Undies For Testicular Cancer Awareness

Ivan “Pudge” Rodriguez just got in front of a camera with his manhood nearly on full display … and he’s hoping the hilarious sight will now help save some lives.

The MLB legend stripped down to his undies as part of a partnership with underwear company Saxx — filming a 75-second commercial with the goal of raising awareness for testicular cancer in mind.

In the vid, Rodriguez rocked a pair of boxer briefs that he insisted held his family jewels “like a catcher’s mitt” … before he introduced a “Ballgorithm” that will ultimately raise cash for the good cause.

Rodriguez and his co-host explained … the algorithm — a math equation centered around the number of bad balls that a pitcher hurls during a contest — will be applied to every Rangers vs. Diamondbacks World Series game this fall … and then that figure will be multiplied by 1,000.

That total number will then be turned into dollars and donated to the Testicular Cancer Foundation — a cause Pudge tells TMZ Sports he cares deeply about.

“The purpose is just to make people laugh and make people aware to go check themselves,” he said, “and we did a nice commercial.”

The MLB Hall of Famer — who’s now working as a special assistant to the general manager of the Rangers — said he’s been catching a lot of ribbin’ both inside and outside of the Texas clubhouse over the vid … but he couldn’t be happier that it might prevent tragedies for people going forward.

“For me, that’s the most important thing,” he said. “Pay attention. This is a disease you can get in the early ages. So, our message is just to go check, because you never know.”
