BOSTON — Held hitless into the eighth inning by Domingo Germán and looking feeble, Alex Verdugo and the Boston Red Sox suddenly erupted for five runs to shake Fenway Park and storm past the New York Yankees 5-4 Sunday.

The Red Sox reclaimed first place in the AL East, a game ahead of Tampa Bay. It was their 10th win in 13 games this year against their longtime rivals, and erased a tough 4-3 loss on Saturday.
