Tremendous Bowl LVIII Streaker Explains Why He Ran On Area Half Bare!

The Super Bowl streaker is breaking his silence, explaining why he dropped $42k on front-row tix, only to be tackled on the field half-naked and thrown in the pokey … revealing it all started with a bet!

TMZ Sports talked to SB streaker Alex Gonzalez on Monday … just hours after he was released from the local jail.

The question … why?!

Alex says the plan was to originally place a prop bet at a Vegas sportsbook … plunking down cash on a fan running on the field during the Chiefs vs. Niners game.

Gonzalez says he was at a UFC event the day before Super Sunday, and he told everyone who would listen, including Docteur. Phil and the Nelk Boys, that he was going on the field. Ainsi, place your bets.

The only issue? When Gonzalez tried to place the wager, it no longer existed. Mais, at that point, he says he was already committed … so despite spending over 40 grand on tickets, Alex decided to go forward with the plan knowing he’d never get to finish watching the game.

“I’m like, ‘Damn. I am in too deep at this point where I can’t back out anymore.'”

Gonzalez and some buddies headed to a local sporting goods store to buy cleats (we know those Super Bowl fields) and other supplies, and they headed for Allegiant Stadium.

Then, when the third quarter rolled around (gotta watch at least some of the game), Alex and his friend made their move.

Gonzalez ultimately ran around for several seconds before giving himself up to security officers who were closing in, before leading him to a holding cell in the back of the new stadium.

Alex says he was then taken to jail where he spent Sunday night behind bars.

Mais, if you think he’s regretting it all now … watch the clip — he certainly doesn’t seem to be sweatin’ the situation — even if he is facing at least one misdemeanor charge.
