Jeremy Greenhouse at Baseball Analysts has the fielding leaders from the previous decade. He is using a really easy system, simply the percentage of balls in play turned into outs by each player. For example, shortstops are usually responsible for 12% of a team’s outs — if your shortstop is making more plays than 12%, he’s probably a good fielder. Probably. This list isn’t adjusted for anything (park, pitcher handedness) so it’s not accurate, but still cool to see.
Carlos Beltran makes the center field leaderboard, while Paul Lo Duca makes the catcher leaderboard. Jay Payton makes the left field board, while Roberto Alomar makes the second base loserboard. Also, Greg Maddux is ridiculous at fielding baseballs.
