C | Buster Posey, Giants
The best of a thriving group of young catchers that includes Matt Wieters and Wilin Rosario, he's already an MVP and a two-time world champ—all before turning 26. He's not just a bat, though: Posey has gunned down base stealers at an above-average rate in each of his three seasons.
CLOSER | Craig Kimbrel, Braves
One-hundred-sixteen out of 231—better than one out of every two. Kimbrel whiffed the majority of the batters he faced in 2012, a feat that no previous pitcher had accomplished (and that none are likely to repeat). He's easily the best closer in baseball.
MANAGER | Joe Maddon, Rays
In today's game no one blends game management with people skills the way Maddon does, and it shows: Tampa Bay has finished above .500 each of the past five years because he lets the front-office stats guys procure the players to win, then keeps them loose, focused and happy.
