Nationals manager Matt Williams was named National League Manager of the Year, the Baseball Writers' Association of America announced on Tuesday.
Pirates skipper Clint Hurdle came in second, while Giants manager Bruce Bochy finished third.
Williams led Washington to a NL-best 96 wins in 2014, his first season as the club's manager.
Hurdle guided Pittsburgh to 88 wins, and a second consecutive postseason berth.
Bochy's Giants defeated Hurdle's Pirates (Wild Card Game) and Williams' Nationals (NLDS) en route to San Francisco's third World Series title in the last five years.
Williams received 18 first-place votes, six second-place votes, and one third-place vote for a total of 109 points.
Hurdle received eight first-place votes, 12 second-place votes, and four third place-votes for a total of 80 points.
Bochy received three first-place votes, three second-place votes, and six third-place votes for a total of 30 points.
A first-place vote counts for five points, second-place is worth three points, and third-place counts for one point.
Voting was conducted prior to the start of the postseason.
Bochy has not won the award since 1996.
