It’s relatively rare for pitching coaches like John Farrell to make the transition to the manager’s chair. And the ones who did generally struggled to find success. A look at how some of the pitching coaches who have become managers have fared in the modern era:
| Manager | Year(s) | Team(s) | Record | Notes |
| Clyde King | 1969-70, 1974-75, 1982 | Giants, Braves, Yankees | 234-229 | Won 90 games his first year, good for second place. Never managed a full season after that. |
| Bob Lemon | 1970-72, 1977-78, 1978-79, 1981-82 | Royals, White Sox, Yankees | 430-403 | Led Yankees to 1978 title after midseason takeover, and again to 1981 pennant. |
| Jeff Torborg | 1977-79, 1989-91, 1992-93, 2001, 2002-03 | Indians, White Sox, Mets, Expos, Marlins | 634-718 | Never finished higher than second. The 2003 Marlins went on to win World Series after his dismissal. |
| Roger Craig | 1978-79, 1985-92 | Padres, Giants | 738-737 | Led Giants to NL pennant in 1989, also won NL West in ’87. |
