Stephen Piscotty returned to the Oakland Athletics on Tuesday night after he missed several games following the death of his mother, and the outfielder made his presence felt immediately. Piscotty, a Bay Area native, was traded by the St. Louis Cardinals to the A's in December, enabling him to care for his mother at their Pleasanton, California, home.
Andrew Benintendi homered for Boston and Mitch Moreland finished with a pair of doubles for the Red Sox. In the ninth, A's closer Blake Treinen gave up his first run in May on an RBI groundout by Mookie Betts before earning his eighth save of the season.
Mengden improved to 3-4 on the season, lowering his ERA to 3.75. The 27-year-old promptly hit a two-out single to center field after acknowledging the crowd's cheers in the second inning of that game.
In his first at-bat of the game in the top of the second, Piscotty belted a solo home run over the Green Monster at Fenway Park.
Red Sox: Placed RHP Carson Smith on the 10-day disabled list Tuesday with a dislocated pitching shoulder, which he injured during a tantrum Monday night.
