Muhammad Ali 'Thrilla in Manila' shorts expected to fetch $6 million at auction

The shorts worn by the great Muhammad Ali in his legendary 1975 boxing bout the "Thrilla in Manila" are expected to be sold for close to $6 million at auction at Sotheby's in New York next week.

Bids for the Everlast-branded white with black stripe shorts have been rolling in since March, including at least one bid of $3.8 million.

The trunks, signed by Ali, were sold for $150,000 in 2012 but are likely to fetch 40 times that sum now, according to Sotheby's.

The auction is open until April 12.

Ali's "Thrilla in Manila" fight against Joe Frazier was held in the Philippines and followed his "Rumble in the Jungle" bout in the Democratic Republic of the Congo (then Zaire) the year before.

Ali's fight in the Philippines went to 14 rounds before Frazier's coach threw in the towel. The fight is considered one of the greatest in boxing history.

"It was like death. Closest thing to dying that I know of," Ali said of the fight, which was held amid stifling heat and humidity, with temperatures heightened by TV lights. Ali, born Cassius Clay in the southeastern state of Kentucky, is known as both a sporting great and for his role in fighting for civil rights for African Americans. He died in 2016 age 74. Frazier passed in 2011 age 67.

As well as being signed by Ali, the Everlast trunks are also inscribed by his corner man, Drew 'Bundini' Brown, who died in 1988 – they fetched just $1,000 (£800) when auctioned after his death.

In 2022, Ali's WBC heavyweight belt from his 1974 “Rumble in the Jungle” fight was sold at auction on Sunday for $6.18 million, making it fourth-most expensive piece of sports memorabilia ever sold.
