Source-derived summary

Stanley Anthony Coveleski (born Stanislaus Kowalewski, July 13, 1889 – March 20, 1984) was an American right-handed pitcher in Major League Baseball who played for four American League (AL) teams between 1912 and 1928, primarily the Cleveland Indians. The star of the Indians pitching staff, he won over 20 games each year from the war-shortened 1918 season through 1921, leading the AL in shutouts twice and in strikeouts and earned run average (ERA) once each during his nine years with the club. The star of the 1920 World Series, he led the Indians to their first title with three complete-game victories, including a 3–0 shutout in the Game 7 finale. Traded to the Washington Senators after the 1924 season, he helped that club to its second AL pennant in a row with 20 victories against only 5 losses, including a 13-game winning streak, while again leading the league in ERA.

Coveleski followed in the footsteps of his brother Harry as a major league pitcher. But after making his debut with the Philadelphia Athletics in 1912, he was sidetracked by three more seasons in the minor leagues before joining the Indians in 1916, and won only 13 major league games before turning 27. Coveleski specialized in throwing the spitball, where the pitcher alters the ball with a foreign substance such as chewing tobacco. It was legal when his career began but prohibited in 1920, with Coveleski being one of 17 pitchers permitted to continue throwing the pitch. In 450 career games, Coveleski pitched 3,082 innings and posted a record of 215–142, with 224 complete games, 38 shutouts, and a 2.89 ERA. He set Cleveland records of 172 wins, 2,502+1⁄3 innings and 305 starts, which were later broken by Mel Harder and Willis Hudlin. He was inducted into the Baseball Hall of Fame in 1969.

Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as american Major League Baseball pitcher during the 1910s and 1920s who primarily threw the spitball (1889–1984). Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Mar 1, 2026. The linked authority identifier is Q11603. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1889, 1984, 1912 and 1928.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it
