A piece of Toronto Blue Jays history could be yours if you’re willing to fork over enough cash.

Per the Goldin Auctions website, the grand slam ball hit by Blue Jays first baseman Vladimir Guerrero Jr. back on October 5th against the New York Yankees has hit the auction block, starting at $1,000. At the time of writing, the current bid was up to $1,200 USD.

The baseball was not authenticated by the Blue Jays or through throught the MLB authentication program, so it is missing the authentication tag/sticker that usually comes with items from the game. The seller of the baseball is Brendan Craig, who caught the baseball and has produced photo matches to show that it is the same ball that he caught in the left field stands.

Reflecting on October 5th, it was the second game between the Blue Jays and the Yankees in the ALDS, with Toronto holding a 1-0 series lead over their division rivals.

The Jays pounced on Yankees pitcher Max Fried early and put up five runs on the left-hander heading into the bottom of the fourth inning. Fried would be replaced by Will Warren that inning after allowing a single and a walk with zero outs, and George Spring would follow suit with a walk of his own to load the bases. While Davis Schneider struck out looking, Vladimir Guerrero Jr. stepped up to the plate ready to put the game on ice for the Jays.

After working to a 2-1 count, Warren tried to bust Guerrero inside with a 95 MPH fastball, and the right-handed bat was able to get a good swing on the baseball, sending it 415 feet and 110 MPH off the bat for the grand slam knock, making it a 9-0 game. It was the first grand slam baseball in franchise history, making it a historic baseball and one of the reasons it is likely heading to the auction block.

Not having the baseball authenticated may drive away some potential bidders, as fakes and non-authentic items in the memorabilia industry are running rampant. However, Goldin is one of the more reputable auction sites out there, and they feel confident enough with the photo match that this is indeed the historic baseball.

The auction does not end for another 16 days on June 6th, 2026, at 10:00 pm EST.
