Back-to-back-to-back-to-back homers. It's an occurrence so rare that it didn't happen for the first time in the Major Leagues until June 8, 1961.
On that day, Milwaukee Braves Hall of Famers Eddie Mathews and Hank Aaron knocked Reds starter Jim Maloney out of the game with back-to-back long balls in the top of the seventh. Cincinnati reliever Marshall Bridges didn't fare any better, serving up home runs to Joe Adcock and Frank Thomas in consecutive at-bats.
It has only happened 10 times since, and, interestingly enough, the Drew brothers were a part of three of them. J.D. Drew hit the second of four straight homers for the Dodgers in 2006 and Red Sox in '07, and Stephen hit the fourth straight for the D-backs in 2010.
Below are the 11 times in Major League history when four consecutive batters went deep.
