Back in the World Series, Walter Johnson dominated the Pirates in Game 1, striking out 10 and beating them 4-1 with a five-hitter.
Game 2 was tied at one apiece until the bottom of the eighth, when Pirates center fielder Kiki Cuyler hit a two-run homer into the right-field bleachers. The Senators loaded the bases with nobody out in the ninth, but could score just one run and lost, 3-2. In Washington for Game 3, the clubs played another tight game. The Senators finished on top, 4-3, on the strength of a two-run seventh.
Johnson started Game 4, and topped his performance in the opener with a six-hit shutout. All of Washington's runs came in the fourth, Goose Goslin accounting for three runs with a long homer into the left-field bleachers. Now the Senators led the Series three games to one, and needed just one more victory for a second straight Championship.
Game 5 would not be that victory, however, as the Pirates piled up 13 hits against four Senator pitchers on their way to a 6-3 decision. Game 6, back in Pittsburgh, was closer, but again the Pirates finished on top, this time 3-2, thereby forcing a seventh game.
Walter Johnson, already twice a winner, didn't have his best stuff in Game 7. Neither did Pirates pitchers Vic Aldridge and Johnny Morrison, however, and after four innings the Senators enjoyed a 6-3 advantage. Johnson tired in the late innings but manager Bucky Harris refused to remove his ace, and the Pirates scored twice in the seventh and thrice in the eighth, clinching the Series with a 9-7 victory. The "goat" of the Series was Washington shortstop Roger Peckinpaugh, who was named American League MVP for the regular season but committed eight errors in Series play, including two in Game 7 that resulted in four unearned runs.
