A downpour at Fenway Park interrupted a matchup between two of the top pitchers in the American League Friday night, but play resumed around 9.
The game was delayed by rain with one out in the top of the fourth inning with the Detroit Tigers leading the Red Sox, 1-0.
Jon Lester was on the mound for Boston, and he allowed a run in the first inning on two walks and two singles. Torii Hunter knocked in the Detroit run with a two-out hit to center.
Tigers ace Max Scherzer faced the minimum nine batters through three innings. He had five strikeouts, and though he did walk Mike Napoli in the second inning, he then induced a double play grounder by Mike Carp.
The game is the opener of a three-game weekend series.
