In 1919, Ruth hit a home run in all how many AL ballparks? He homered in all eight American League ballparks.
The 1919 American League had eight teams, each with its own home park. Ruth became the first major-league player to hit at least one home run in every park in his league during the same season, completing the feat with his 29th homer in Washington against the Senators.
That achievement was especially notable because Ruth was still playing in Boston and had to visit the other American League cities as a road player. The accomplishment was not simply eight home runs: it required at least one homer in each of the league’s eight venues, including Boston’s Fenway Park.
Readers sometimes confuse this record with Ruth’s later totals at Yankee Stadium or with his 1919 home-run record. The two feats were connected: the Washington blast both gave him the league-wide park sweep and finished his record-setting season total.
