Congratulations to Bobby Cox and Ozzie Guillen. Mike Hargrove will have to wait another year.
If you want to use the questionable mathematical argument that team performance above or below its Pythagorean record is an indicator of managerial acumen, then Guillen was the right choice in the AL (+8 wins), while Cox was rather undeserving (-1 win, as compared to Bob Melvin's +12).
If you want something that's a lot easier to understand, though, Guillen was at the helm when what should've been a fringe contender caught fire and won the World Series, and Cox fended off a tough division with a team full of rookies, guiding the Braves to their 87th consecutive NL East title.
No surprises here.
