New York Yankees star Aaron Judge had his worst performance of the season this weekend as the team was swept by the rival Boston Red Sox, going 1-for-12 over the three-game series.

Facing the Red Sox (37-36) on back-to-back weekends, the Yankees (42-28) dropped five of six and seemingly gave life to their rival’s season. In The Bronx, it was their pitching that failed them. At Fenway, it was their lifeless bats, plus a costly baserunning miscue in each of the past two games.

In the top of that inning, Anthony Volpe, the Yankees’ automatic runner, was thrown out trying to steal third base with nobody out. He was initially ruled safe at third, but the call was overturned after Boston challenged the play.
