Mayer’s home run is the lone positive for Boston so far in this game. The Sox trail 8-1 in the sixth inning. The Yankees pounded starter Walker Buehler for seven runs (five earned), seven hits, two homers and two walks in the first two innings.

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.
