The best ten managers in New York Yankee history:
10) Yogi Berra: In slightly more than two years as manager, Berra had a 192-148 record, for a .565 winning percentage. He led the team to the 1964 World Series, but was stuck with a middling team in 1984, when George Steinbrenner saddled him with mediocre players.
9) Clark Griffith: From 1903-1908 Griffith had a 419-370 record, a .531 winning percentage.
8) Buck Showalter: In 1995 Showalter led the Yankees to their first playoff appearance since 1981, a fourteen year drought. In four years at the helm he had a winning percentage of .539, with a 313-268 record.
7) Ralph Houk: Managing the team for 11 years, Houk led the Yankees as they went from the top of the baseball world in 1961 to its bottom depths in the late '60's and early '70's. He finished with a 944-806 record, a winning percentage of .539.
6) Joe Girardi: The Yanks have made the playoffs in four of Girardi's six years with the team. His record is 564-408, a .580 winning percentage, with one World Series title. Girardi has done a good job managing his pitching staff and bullpen.
5) Billy Martin: Taking five turns as manager, Martin ended up with a 556-385 record, a .591 winning percentage. The team won pennants under his helm in 1976 and 1977, taking the World Series title in '77.
4) Miller Huggins: With the game's best players in Babe Ruth and Lou Gehrig on his roster, Huggins compiled a 1067-719 record, a .597 winning percentage, from 1918-1929. A monument at Yankee Stadium was erected in his honor.
3) Joe Torre: Torre led the Yanks to four world championships in 12 seasons, from 1996-2007. His 1173-767 record, a .605 winning percentage, demonstrates consistency while facing adversity as manager.
2) Casey Stengel: In 12 years from 1949-1960, Stengel won seven World Championships, plus three more American League pennants. His 1149-696 won-loss record gives him a winning percentage of .623.
1) Joe McCarthy: The longest tenured Yankee manager at 16 years, McCarthy holds the record for most wins as Yankee manager, and his 1460-867 regular season record gives him a winning percentage of .627, which is also tops among Yankee managers who were at the helm for more than one season. His teams won seven World Championships from 1931-1946.
