The only punches thrown in The Bronx on Friday came from the Yankees’ bats, and they did not waste any time landing them.

Warren held Boston scoreless through four innings, then surrendered a home run to 22-year-old Marcelo Mayer to lead off the fifth. It was the first career homer for Mayer, one of baseball’s premier prospects, in his 10th MLB game.

Anthony Volpe homered in a five-run first inning, then came out after he was hit by a pitch on the left elbow as the New York Yankees beat the Boston Red Sox 9-6 in the AL rivals’ first meeting this year.
