The Haight Street Grounds ran from 1886-1895 and were located between Stanyan, Waller, Shrader and Frederick streets. The grandstands would seat 14,000. In 1887, both the Pioneers and Haverlys were making strenuous efforts to win the California League pennant, but the smallest margin divided them. A close and exciting game was expected on October 9. It was reported that every seat was occupied at some point before the bottom of the ninth inning at a time when interest in baseball in San Francisco was on the rise. The Haverlys managed six consecutive safe hits in the sixth inning, but did not make any runs in any other inning of the game. The Pioneers won eleven to six, putting them in first place standing in the California League, and making them favorites to win the pennant, with the Haverlys a close second and the Greenhood and Morans anchored in the last rung. The season ended on November 21, 1887 as predicted; the Pioneers won the pennant with 24 wins to the Haverlys 23.
