Miami Marlins 1st Baseman -- Using Ultimate Warrior Music ... For Entire MLB Season

The Ultimate Warrior will live on in Miami -- because Marlins 1st baseman Garrett Jones tells TMZ Sports he'll be using the wrestler's theme song as "walk up music" for the rest of the season.

Jones tells us ... he was a HUGE Warrior fan growing up -- and was incredibly saddened by his death earlier this week.

The day after Warrior passed away, Jones asked the Marlins' crew to play his theme music when he walked up to bat ... and it felt so right, he's decided to use it for the rest of the season.

"The Ultimate Warrior was my number one favorite. I was a huge wrestling fan. Unfortunately, I never got to see him live, but I loved him as a wrestler. What he said was motivational. His energy ... it inspired me."

Jones says UW had a certain "Warrior persona" that struck a chord with him -- "It sounds silly but you grow up and become an athlete and that sticks with you. You can apply the things he said to life."
