The Rex Foundation and the MLB have teamed up to celebrate Jerry Day, a celebration of Jerry Garcia, with a run of auctions set to occur from July 26 through Aug. 7. The participating teams include The Boston Red Sox, The San Francisco Giants and The New York Yankees.

The prizes include Jerry Bobbleheads, exclusive entry and seating but the most notable item being auctioned is not an item but the experience of throwing The Ceremonial First Pitch from the pitcher’s mound ahead of the game. All the participating teams are offering this once-in-a-lifetime fan opportunity during Jerry Night.

The Red Sox are set to honor Garcia on Aug. 9, and their auction is open from July 26 through Aug. 7, The San Francisco Giants will honor Garcia on Aug. 2, and their auction runs through Aug. 1, and the Yankees will honor Garica on Aug. 1 with their auction ending on July 30.

In the case of the Yankees, they are also offering up an opportunity for a child to hand the ump the lineup card, primo seats in the Legends section with Club access and tickets to the Judge’s Chambers section.
