Brayan Bello pitched seven innings of three-hit ball, leading the Boston Red Sox to a 1-0 victory over the New York Yankees that clinched the season series between the longtime rivals.

A squirrel ran onto the field during Friday night’s game between the Yankees and the Red Sox and caused a brief delay. The fast-moving mammal emerged from an area behind the plate in the fourth inning and stopped behind Boston rookie Jhostynxon Garcia’s left foot as the outfielder took a timeout and adjusted his batting gloves.

After an eighth straight loss against the Red Sox, the Yankees are running out of time to prove they belong in the playoffs.
