Handwritten letter signed in black ballpoint ink by Stan Coveleski. Creasing throughout, otherwise, in very good condition. 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 epidemic-shortened 1918 season through 1921, leading the AL in shutoutstwice 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.
