Yoshida also singled during Boston's two-run first inning and was credited with a double in the eighth on a ball that Pittsburgh left fielder Jack Suwinski appeared to lose in the sun.

Kenley Jansen struck out the side in the ninth to earn his fifth save. Pittsburgh manager Derek Shelton was ejected after Michael A. Taylor struck out on a pitch-clock violation with one out in the ninth.

Pittsburgh made it a 2-1 game in the bottom of the fourth. Ke'Bryan Hayes led off the inning with a double and scored on Jared Triolo's two-out single.
