The Providence Grays went 84–28 during the 1884 season to win the National League championship. The team started out with two main pitchers, Charles "Old Hoss" Radbourn and Charlie Sweeney. After Sweeney jumped to the Union Association in mid-season, Radbourn pitched most of the Grays' remaining games and led the team to the pennant. Radbourn won 60 games by himself, setting a Major League Baseball record that has never been broken.
After the regular season, the Grays faced the American Association champions, the New York Metropolitans, in the 1884 World Series. The Grays swept the series to become the "World Champions."
Summary
Background
In 1883, the Providence Grays finished in third place. Pitcher Charles "Old Hoss" Radbourn won 48 games. Before the 1884 season, manager Harry Wright left the team and was replaced by Frank Bancroft. The franchise was on shaky financial ground, and ownership was close to disbanding the team.
Pitching rivalry
In early 1884, the Grays' two main pitchers were Radbourn and Charlie Sweeney. Both Radbourn and Sweeney were talented pitchers but also vain and temperamental. Through much of April and May, the younger Sweeney outshone the veteran Radbourn, creating tension between the two.
On June 7, 1884, Sweeney struck out 19 Boston batters to set the single-game MLB record. The record would be tied a few times but not broken for 102 years, until Roger Clemens struck out 20 in a game in 1986. Sweeney was feted upon his return to Providence for days following his accomplishment, much to the bitter jealousy of Radbourn.
Not long after that, Sweeney suffered arm problems which sidelined him. This meant that Radbourn would suffer the workload of two men, further driving a wedge between the veteran and the upstart. The two eventually fought in the clubhouse, and on July 16, Radbourn had a meltdown on the mound, intentionally lobbing several slow pitches over the plate in a losing effort. He was suspended from the team. Sweeney was forced to return to his regular pitching duties, which he did effectively for a time.
Sweeney's blowup
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 at the time were held to temperance clauses during the season, Grays manager Frank Bancroft was left with little choice but to pitch Sweeney.
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. With the Grays leading 6–2 before the start of the eighth inning, Bancroft insisted that Sweeney vacate the pitcher's box and move to right field. Still intoxicated, 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. This left Providence with only eight players. With two men to cover the outfield, they lost the game. Sweeney watched the rest of the game in street clothes and left with two women, presumably prostitutes. The Grays subsequently expelled Sweeney from the National League.
Sweeney then signed with the St. Louis Maroons of the Union Association, helping the Maroons win the UA's only championship. For the season, Sweeney pitched 221 innings for the Grays, going 17–8 with a 1.55 ERA, and pitched 271 innings for the Maroons, going 24–7 with a 1.83 ERA.
Radbourn's record
With only one main pitcher left, the Grays were left in a state of disarray with the consensus view that the team should be disbanded. At that point, Radbourn, who had spent the last several weeks demanding he be paid for doing the work of two men, offered to start every game for the rest of the season (having pitched in 76 of 98 games the season before). In exchange, he wanted a raise and exemption from the reserve clause for the next season. Ownership agreed, and Radbourn got his raise.
