Stover McIlwain

In his two big league appearances and five innings pitched, McIlwain did not record a win or a loss, gave up six hits and just the one earned run for a lifetime earned run average of 1.80. He notched four strikeouts, all during his 1958 starting assignment. His minor league pitching career, spent entirely in the White Sox' farm system, extended from 1957 through 1963, with 1961–62 spent in military service.

McIlwain's two MLB games took place during consecutive Septembers, with a relief appearance in 1957 against the Detroit Tigers and a starting assignment against the Kansas City Athletics in 1958. In the latter game, McIlwain allowed a home run to Lou Klimchock, the game's leadoff batter, but then settled down to pitch four innings without further scoring, allowing four hits and no bases on balls. He left for a pinch hitter in the home half of the fourth inning with a 2–1 lead and Chicago eventually won 11–4.
