July 1st, 1873 - It is officially a 5 team race with Boston lurking 2 1/2 games behind the Mutuals and Athletics, who are tied for first. Perhaps the biggest surprise is the Brooklyn Atlantics who, though improved from last year, may not have been expected to play this well so far. The Philadelphia White Stockings have failed to perform, mostly due to starting pitcher George Zettlein's 4.34 ERA.
