You could catch an exceptional piece of baseball history this month.

The baseball with which Los Angeles Dodgers star Shohei Ohtani scored his second home run in Game 4 of the National League Championship Series (NLCS) will be auctioned off in an online sale starting November 5. It is expected to fetch at least $1 million, according to SCP Auctions.

Two-way player Ohtani, affectionately nicknamed “Shotime,” helped the Dodgers defeat the Milwaukee Brewers 5-1 at Dodger Stadium on October 17, giving the team a clean, four-game sweep, securing the championship title, and advancing them to the World Series for the second consecutive year. In addition to hitting three homers a total of 1,342 feet, Shotime also threw 10 strikeouts and allowed no runs over six innings pitched. Many consider it to be the greatest single-game performance in baseball history. 

It was certainly the best performance of Ohtani’s career. He led off the bottom half of the first inning with a 446-foot missile into the rightfield bleachers, becoming the first starting pitcher to hit a leadoff homer in MLB history. In the fourth inning, he delivered a 469-foot moonshot that literally left the stadium. He went on to smash a 427-foot big fly into the left-center bleachers in the seventh inning. 

The ball on offer is the one that Chad Patrick hurled at Ohtani in the fourth. Showtime sent it over the rightfield pavilion roof and outside the stadium, achieving one of the longest homers in the history of Dodger Stadium. “They said it went 469 feet,” Dodgers third baseman Max Muncy said after the game. “That’s wrong. That ball was at least 500 feet. That’s the farthest ball I’ve ever seen hit.” A special plaque has already been added to the stadium in honor of the incredible feat.

The ball was consigned by Carlo Mendoza, who jumped into the bushes of centerfield to retrieve it. “As I was taking a bite of my nachos, I saw Ohtani hit his second homer,” Mendoza told NBC LA. “Then I see a guy in front of me look up—and I think, ‘no way the ball comes out here.’ Next thing I know, it bounces off the roof and into the bushes.”

SCP hasn’t given a pre-sale estimate, but expects the lot will “bring a seven-figure result.” Ohtani’s 50th home run ball hammered down for a record $4.39 million at Goldin last October, becoming the most expensive baseball ever sold at auction. The Game 4 ball will be offered as part of SCP’s fall event, with bidding open from November 5 to 22. For more information, visit the SCP website or call (949) 831-3700.
