BOSTON — Cleveland pitcher Zach Plesac threw the ball completely out of Fenway Park as the grounds crew began to bring out the tarp, and the Boston Red Sox ended a five-game losing streak by beating the Guardians 3-1 Monday night.

Alex Verdugo hit a tiebreaking double and Boston’s bullpen worked 3 1/3 scoreless innings. The Red Sox are just 6-15 in July and remain only a half-game ahead of last-place Baltimore in the AL East.

José Ramírez drove in Cleveland’s run with an infield hit. It was the third straight loss for the Guardians.

Yolmer Sánchez hit an RBI single in the third to put Boston ahead 1-0. Home plate umpire and crew chief Dan Iassogna then called for the grounds crew to roll out the tarp and Plesac fired the ball from near the mound over the third-base roof and out of the ballpark.

The game was delayed 38 minutes by rain.

Wearing their “city connect” yellow-and-powder blue uniforms, the Red Sox broke a 1-1 tie with two runs in the sixth, chasing Plesac (2-8).

Verdugo doubled off the Green Monster and Rob Refsnyder raced home when the ball bounced over left-fielder Steven Kwan back toward the infield as he fell to the ground trying to play the carom. Christian Vázquez added a bloop RBI single off reliever Trevor Stephan.

John Schreiber (3-1) got Myles Straw to ground out with two runners on to end the sixth before pitching the seventh. Garrett Whitlock got six outs for his second save.

Making his first start since July 15 because of the All-Star break, Plesac was charged with three runs in five-plus innings, allowing only three hits.

Boston starter Nick Pivetta gave up seven singles and one run over 5 2/3 innings.
