On October 10, 1904, 41-game winner Jack Chesbro of the Highlanders let loose a wild pitch in the ninth inning of the final game of the season. This snapped a 2-2 tie, allowing Pilgrims right-hander Bill Dinneen to claim victory as the Boston team claimed the AL pennant. Dinneen finished the year having completed every game he started during the season, throwing 337.2 consecutive innings without relief during his streak of 37 consecutive complete games.
The first game of what would become baseball’s fiercest rivalry took place on May 7, 1903 at Huntington Avenue Grounds in Boston. The Pilgrims won 6-2 over the Highlanders, as Hobe Ferris belted a home run and Chick Stahl hit two triples. Meanwhile, Highlanders pitcher Snake Wiltse gave up thirteen hits in the loss. Today, these two teams are known as the Boston Red Sox (the Pilgrims) and the New York Yankees (the Highlanders).
