According to ESPN, Betts tied the record for homers in two games with five. After his two homers Wednesday, he had five homers in his past seven at-bats.
Betts is the first Red Sox player to lead off consecutive games with a homer since Mike Aviles on May 19-20, 2012, in Philadelphia.
Betts hit a career-high three homers Tuesday, becoming the first Red Sox leadoff hitter to go deep three times in a game. His first-inning blast Wednesday was his fifth career leadoff homer and his third since May 11.
The 23-year-old leads the Majors with 14 homers and 42 RBIs as a leadoff hitter this season.
