Boston hit four straight home runs as they beat arch rivals the New York Yankees 7-6 to seal a 3-0 series sweep.
It was the first time in franchise history that the Red Sox had scored four consecutive homers - and only the fifth time in the major leagues.
Mike Lowell, who hit the third of the sequence said: ""I haven't been a part of anything like that, not even in Little League."
Yankees starter Chase Wright was the pitcher punished by the Red Sox.
Manny Ramirez, JD Drew and Jason Varitek were the other Boston scorers in the rare burst.
