300-win club

Seven pitchers recorded all or the majority of their career wins in the 19th century: Galvin, Cy Young, Kid Nichols, Keefe, John Clarkson, Charles Radbourn, and Welch.

[2] Four more pitchers joined the club in the first quarter of the 20th century: Mathewson, Walter Johnson, Eddie Plank, and Grover Cleveland Alexander.

Only three pitchers—Lefty Grove, Warren Spahn, and Early Wynn—joined the 300-win club between 1924 and 1982, which may be explained by a number of factors: the abolition of the spitball[1][a]; World War II military service, such as Bob Feller's;[5] and the growing importance of the home run in the game.

[1][2] Between 1982 and 1990, the 300-win club gained six members: Gaylord Perry, Phil Niekro, Steve Carlton, Nolan Ryan, Don Sutton, and Tom Seaver.

[2] Also, the increasing sophistication of training methods and sports medicine - such as Tommy John surgery - allowed players to maintain a high competitive level for a longer time.
