With Yankee Stadium still but a gleam in club owner Jacob Ruppert's eye, 1921 witnessed the first World Series played entirely in one ballpark, the Polo Grounds.
The Yankees opened strong, behind Carl Mays' five-hitter in Game 1 and Waite Hoyt's three-hitter in Game 2, both games resulting in 3-0 shutouts. The Yankees then took a 4-0 lead in Game 3, but the Giants came back with four of their own in the bottom of the fourth inning, and then they exploded for eight tallies in the seventh on their way to a 13-5 blowout. Giants right fielder Ross Youngs doubled, tripled, and knocked in four runs.
Game 4 saw the Giants even the Series at two apiece, as Shufflin' Phil Douglas outpitched Carl Mays, 4-2. Hoyt put the Yankees back on top in Game 5, besting Art Nehf, 3-1.
In Game 6, Giants starter Fred Toney - who had lasted only two-plus innings in Game 3 - couldn't escape the first inning as the Yankees posted three runs despite the absence of injury-plagued Babe Ruth, who wouldn't start again. But the Giants bounced back with three runs in the second and four more in the fourth, rolling to an 8-4 victory behind the solid relief work of Jesse Barnes.
Game 7 was a rematch of Game 4, and this time Douglas beat Mays 2-1. The deciding run scored in the seventh when Frank Snyder doubled home Johnny Rawlings.
In the first inning of Game 8, the Giants had men on first and second with two out when George Kelly shot a grounder toward Yankee shortstop Roger Peckinpaugh, who had played flawless defense to that point. The ball went straight through Peckinpaugh's legs, Dave Bancroft scoring from second. That would be the Giants' only run of the game ... and the only one they would need, as Nehf tossed a four-hit shutout to clinch the Series.
