Shohei Ohtani’s 50th home run ball has sold at auction for $4.392 million, a record high price not just for a baseball, but for any ball in any sport, the auctioneer said Wednesday.

Ohtani became the first player in baseball history to hit 50 homers and steal 50 bases in a season, reaching the milestone on Sept 19 when the Los Angeles Dodgers star hit his second of three homers against the Marlins.

“We received bids from around the world, a testament to the significance of this iconic collectible and Ohtani’s impact on sports, and I’m thrilled for the winning bidder,” Ken Goldin, the founder and CEO of auctioneer Goldin Auctions said in a statement.

The auction opened on Sept 27 with a starting bid of $500,000 and closed just after midnight on Wednesday. The auctioneer said it could not disclose any information about the winning bidder.

The previous record price for a baseball was $3.05 million which was paid for Mark McGwire's 70th home run ball in 1998.

The auction has been overshadowed by the litigation over ownership of the ball. Christian Zacek walked out of Miami's LoanDepot Park with the ball after gaining possession in the left-field stands. Max Matus and Joseph Davidov each claim in separate lawsuits that they grabbed the ball first.

All the parties involved in the litigation agreed that the auction should continue. The money will be kept in a bank account until the court decides the ball's owner.

Matus’ lawsuit claims that the Florida resident — who was celebrating his 18th birthday — gained possession of the Ohtani ball before Zacek took it away. Davidov claims in his suit that he was able to “firmly and completely grab the ball in his left hand while it was on the ground, successfully obtaining possession of the 50/50 ball.”

Ohtani and the Dodgers are preparing for Game 1 of the World Series scheduled for Friday night.
