This is for non-pitchers since 1901:
|Position/Research Link||Greatest All-Time||Honorable Mention||Greatest Active|
|C||Yadier Molina||Jim Sundberg||Yadier Molina|
|1B||Keith Hernandez||John Olerud||Mark Teixeira|
|2B||Joe Gordon||Mark Ellis||Chase Utley|
|3B||Brooks Robinson||Clete Boyer||Evan Longoria|
|SS||Mark Belanger||Jack Wilson||Brendan Ryan|
|LF||Barry Bonds||Bernard Gilkey||Carl Crawford|
|CF||Paul Blair||Devon White||Austin Jackson|
|RF||Jesse Barfield||Roberto Clemente||Ichiro Suzuki|
Of course, this list means no disrespect to players like Willie Mays, Tris Speaker, Johnny Bench, Ivan Rodriguez, Ozzie Smith, Luis Aparicio, Adrian Beltre, Mike Schmidt, Bill Mazeroski, Frank White, Bill Terry, Vic Power, Dwight Evans, Dave Parker, Rickey Henderson and others. It’s just that I think those listed above are the best defensively, all-time and currently, based only on their merits in the field (and not including what they did at bat). Your mileage may vary….
…but, I encourage you to click the links in the Position/Research Link column to see the data behind these selections.
