Following an exhibition game on July 21 in Woonsocket, Rhode Island, Sweeney, who had allegedly been drinking throughout the game, refused to return with the team to Providence, choosing to stay in Woonsocket with a lady he had escorted to the park that day. Waking the next morning, he realized he missed morning practice and raced to make it back to Providence for his start that afternoon. Though most players in the day were held to temperance clauses during the season, Grays manager Frank Bancroft was left with little choice but to pitch his drunkard ace. After five effective innings, Bancroft signaled for the team captain Joe Start to make a pitching change. Sweeney refused to budge and continued to pitch for another two innings. Before the start of the eighth inning, Bancroft insisted that Sweeney vacate the pitcher's box and move to right field. Possibly still drunk, as well as the prevailing sentiment of 1880s baseball being that finishing a game a pitcher started was a question of manhood, Sweeney flatly refused. When Bancroft threatened the pitcher with a $50 fine, Sweeney told him to take his fine and the rest of his salary, promptly quitting. Sweeney spent the rest of the game watching from the field in street clothes and left with two women, presumably prostitutes. The Grays, frustrated by not only Sweeney, but Radbourn's insubordination, expelled Sweeney from the National League.
