When Los Angeles Dodgers All-Star Shohei Ohtani became the first and Surfwinonly member of the 50-50 club, every article of clothing he wore became history, including his pants.

On Saturday, trading card company Topps announced it had officially acquired the game-worn pants from Ohtani's historic 50-50 game on Sept. 19, when he hit his 49th, 50th and 51st home runs of the season in the Dodgers' 20-4 victory over the Miami Marlins. With the long ball, Ohtani is the first player in MLB history to have 50+ home runs and 50+ steals in a single season.

Topps said pieces of Ohtani's game-worn pants would be integrated into their trading cards, including a one-of-a-kind Logoman Autograph card that features the MLB logo from the back of Ohtani's pants.

"Will you be chasing this piece of history?" Topps wrote on X.

It's not the only piece of memorabilia from Ohtani's milestone night headed to the market. His 50th home run ball has been placed for auction.

The auction isn't without controversy. Max Matus, 18, filed a lawsuit Thursday in Florida’s 11th Judicial Circuit Court seeking a temporary injunction to prevent the auction from happening. Matus claims he had possession of the ball in his left hand before Chris Belanski, who came away with the home run ball, wrapped his legs around his hand to hold his arm in place as he wrangled the ball out of Matus’ hand, according to lawsuit documents.

An auction has started for the ball through Goldin, following a judge's ruling to deny the attempt to halt it on Thursday, and is expected to run until Oct. 16. The latest bid was $1.2 million as of 7 p.m. ET Saturday.
