When All-Star Shohei Ohtani of the Los Angeles Dodgers made history by becoming the first player to enter the 50-50 club, every item he wore during that game took on significance, especially his pants.

On Saturday, Topps, a prominent trading card company, announced that they have officially secured Ohtani’s game-worn pants from his remarkable 50-50 game on September 19. During this game, he hit his 49th, 50th, and 51st home runs, contributing to the Dodgers’ 20-4 win against the Miami Marlins. This achievement makes him the first player in MLB history to hit over 50 home runs and steal over 50 bases in a single season.

Topps revealed that pieces of Ohtani’s pants will be included in their trading cards, including a unique Logoman Autograph card featuring the MLB logo taken from the back of his pants.

“Will you be trying to get this piece of history?” Topps asked on X.

But that’s not all from Ohtani’s special night; his 50th home run ball is also on the auction block.

The auction has sparked some controversy. Max Matus, an 18-year-old, has filed a lawsuit in Florida’s 11th Judicial Circuit Court, aiming for a temporary injunction to stop the auction of the ball. Matus alleges that he was holding the ball in his left hand when Chris Belanski, who ended up with the home run ball, held his legs around Matus’ hand to secure the ball, according to court documents.

The auction for the ball is currently underway at Goldin, following a judge’s decision to deny the request to stop it. Bidding is anticipated to last until October 16, with the latest bid reaching $1.2 million as of 7 p.m. ET on Saturday.
