August 25, 2011: The Yankees make MLB history by hitting three grand slams in a game, a 22-9 win against the A's.
Robinson Cano, Russell Martin and Curtis Granderson combined for the record-setting power surge.
The Yankees trailed 7-2 in the fifth inning when Cano connected against Rich Harden to cut the lead to one run.
In the sixth, Martin's slam off Fautino De Los Santos gave the Yankees their first lead at 10-7.
In the eighth, Granderson made history against Bruce Billings.
There had been multiple occasions of a team hitting two grand slams in a game. The most recent for the Yankees was Sept. 14, 1999, at Toronto with Bernie Williams and Paul O'Neill.
