On this day in 1948 Tom Trebelhorn was born in Portland, Oregon. He played five years in the minor leagues in the Angels and A's organizations but his playing days were over by 1974, freeing him up to move on to coaching.
Trebelhorn was just 38 years old but had already managed nearly 800 games in the minors when the Brewers called upon him to replace George Bamberger on an interim basis for the final nine games in 1986. He had the interim tag removed from his title in 1987 and led the Brewers to 91 wins, the sixth highest total in franchise history and only the third highest since 1982.
All told Trebelhorn went 422-397 at the helm of the Brewers and his teams finished with a winning record in four of his five seasons. He's one of just four Brewers to manage over 200 games and leave with a winning record:
| Manager | Games | Wins | Losses | W-L% |
| Harvey Kuenn | 279 | 160 | 118 | .576 |
| Buck Rodgers | 226 | 124 | 102 | .549 |
| George Bamberger | 728 | 377 | 351 | .518 |
| Tom Trebelhorn | 819 | 422 | 397 | .515 |
Trebelhorn is third on the Brewer all-time wins list behind Phil Garner (563-617) and Ned Yost (457-502).
Despite having a good record at the helm, Trebelhorn has only managed one big league season since leaving the Brewers: He went 49-64 as the Cubs' skipper during the strike-shortened 1994 season. He's spent the last four years managing the Salem-Kaizer Volcanoes (short season A ball) in the Giants organization.
Trebelhorn turns 64 today. With help from the B-Ref Play Index, we'd also like to wish a happy birthday to:
- 2003 Brewer Jason Conti, who turns 37.
- 1998 Brewer Greg Martinez, who turns 40.
