Yairo Munoz went 3-for-3 with his first home run as a member of the Red Sox on Friday. He also doubled. But Boston lost 8-7 in the first game of a doubleheader with the Blue Jays at Fenway Park.

Starter Zack Godley gave up a 418-foot solo homer to Travis Shaw and a 412-foot two-run homer to Danny Jansen as Boston fell behind 3-0 in the second inning.

Red Sox pitchers have allowed an MLB-leading 69 homers in 39 games. Boston dropped to 12-27 (.308 winning percentage).

Munoz, who the Red Sox signed to a minor league contract March 25 and promoted Monday, bashed his homer 395 feet. It left the bat at 99.5 mph. His two-run blast cut Boston’s deficit to 3-2.

Munoz also hit an RBI double during Boston’s three-run rally in the sixth inning. The rally cut the deficit to 8-7.

Munoz spent the past two years in the Cardinals organization after the Oakland Athletics traded him to St. Louis for Stephen Piscotty.

But he abruptly left 2020 spring training camp after a hamstring injury and a dispute with the Cardinals over playing time. He left camp and returned to the Dominican Republic without telling St. Louis, who released him March 7.

He appeared in 196 big league games in 2018-19, batting .273 with a .331 on-base percentage, .391 slugging percentage, .723 OPS, 10 homers, one triple, 23 doubles, 55 RBIs, 13 stolen bases and 59 runs (510 plate appearances).

Alex Verdugo, Kevin Plawecki and Michael Chavis each stroked two hits.

Game 2 was still in progress as The Sentinel went to press Friday night.
