Hitting back-to-back homers is rare enough. But the same two players doing it TWICE in the same game? That’s truly special.

On Monday night against the Orioles, Red Sox sluggers Rob Refsnyder and Tyler O'Neill became the latest duo to pull off one of baseball’s oddities, going back to back in the third inning at Fenway Park and AGAIN in the eighth in Boston’s 12-3 victory.

Refsnyder and O’Neill are the second pair of Red Sox hitters to hit back-to-back dingers multiple times in the same contest and the 24th such pair of MLB batters in the Expansion Era (since 1961), according to the Elias Sports Bureau.
