The most exciting game of ball ever played in this city was that between the Bostons and Brown Stocks at Grand Avenue Park yesterday afternoon, which was witnessed by at least 6,000 spectators, who shouted themselves hoarse. All the seats were densely packed, and the limits of the field were encircled by a live cordon of sweltering humanity. The red-legged champions were unlucky enough to lose the toss, and Mr. Wm. Medart, of St. Louis, was chosen to act as umpire. The champions presented Geo. Wright, Leonard, Manning, Shaefer and O'Rourkke, of their old team, Tim Murnan, formerly of the Philadelphias, and Brown, Whitney and Morrill, three promising young players who had never before been seen on a St. Louis ball ground. All three created a favorable impression, Brown especially, who is without doubt one of the most effective catchers in the country. The Bostons took the lead in the third inning and maintained it until the ninth, when the Browns were allowed tp get even with them, principally by a bad muff of O'Rourke's. The tenth and eleventh innings did not add to the score, but in the twelfth, Morrill, by the errors of Clapp and Pike, and O'Rourke's timely hit, tallied, and this proved to be the winning run. The home team was outbatted and outfielded at all points...George Wright was the bright particular star.-St. Louis Globe-Democrat, July 5, 1876
That's an odd reference to the "Brown Stocks" and I'm not certain if it's intentional or just a misprint.
