A scout for the New York Yankees discovered Stottlemyre pitching for Yakima's baseball team, and signed him to a contract with no signing bonus on June 10, 1961. The Yankees assigned him to the Harlan Smokies of the Rookie-levelAppalachian League. After appearing in eight games, the Yankees promoted him to the Auburn Yankees of the Class DNew York–Penn League, and he appeared in seven games for Auburn. Stottlemyre pitched to a 17–9 win–loss record and a 2.50 earned run average with the Greensboro Yankees of the Class BCarolina League in 1962, and was promoted to the Richmond Virginians of the Class AAAInternational League in 1963. He alternated between starting and relieving for Richmond, before Ralph Houk, the Yankees' general manager, insisted that Stottlemyre be used exclusively as a starting pitcher. He recorded a 1.42 ERA in the 1964 season, the best in the International League. Called up midseason in 1964, Stottlemyre went 9–3 to help the Yankees to their fifth consecutive pennant while being on the cover of The Sporting News. In the 1964 World Series, Stottlemyre faced Bob Gibson of the St. Louis Cardinals three times in the seven-game Series. Stottlemyre bested Gibson in Game 2 to even the series, and got a no-decision in Game 5, but lost the decisive Game 7 as the Cardinals won the Series. Stottlemyre was named to the American League's roster for the 1965 Major League Baseball All-Star Game, though he did not appear in the game. He won 20 games in the 1965 season, and led the AL with 18 complete games, 291 innings pitched, and 1,188 batters faced. He appeared in the 1966 MLB All-Star Game. He led the league with 20 losses. Stottlemyre won 20 games in the 1968 and 1969 seasons. He also started the 1969 MLB All-Star Game. Stottlemyre threw 40 shutouts in his 11-season career, the same number as Hall of Fame lefty Sandy Koufax, which ties for 44th best all-time. Eighteen of those shutouts came in a three-season span from 1971–73. The Yankees released Stottlemyre before the 1975 season. Stottlemyre retired with 164 career wins and a 2.97 ERA. Known as a solid-hitting pitcher, on July 20, 1965, Stottlemyre hit a rare inside-the-park grand slam. On September 26, 1964, he recorded five base hits in five at bats.
Coaching years (1984–2008)
In 1977, Stottlemyre re-emerged in baseball as a roving instructor for the Seattle Mariners. He spent five seasons in that position, and was hired by the New York Mets as their pitching coach in November 1983. He served in the role for ten years and then followed that by serving a two-year stint as the Houston Astros pitching coach.
New York Yankees (1996–2005)
In 1996, Stottlemyre joined the Yankees coaching staff along with the incoming managerJoe Torre. Under Torre, Stottlemyre lowered the team ERA from 4.65 in 1996 to 3.84 in 1997. Under Stottlemyre, the Yankee team averaged an ERA of 4.23 from 1996 to 2005. The pitching staff was regarded as a major factor in the team's dynasty years, when they won four World Series Championships in five years. After 10 seasons, Stottlemyre resigned his coaching position on October 12, 2005, following the Yankees' defeat in the 2005 American League Division Series by the Los Angeles Angels of Anaheim. He cited personal disagreements with Yankees owner George Steinbrenner among his reasons for leaving and cited Steinbrenner's comment that, after the division series was over, he had congratulated Angels manager Mike Scioscia. Stottlemyre's response was: "My first thought was, 'What about Joe?' Joe did a hell of a job, too. To congratulate the other manager and not congratulate your own, after what he's done this year, I laughed." The Yankees replaced Stottlemyre with former Yankees pitcher Ron Guidry.
Seattle Mariners (2008)
Stottlemyre was named pitching coach of the Seattle Mariners under manager John McLarenat the beginning of the 2008 season, and was retained by interim manager Jim Riggleman after McLaren's firing. He was dismissed after the season ended. Following the season, he retired from baseball.
