Catcher– Darrin Fletcher, Expos, (’89-’02) — Thurman Munson holds the top two marks for worst fielding percentage, but it’s not nice to speak ill of the dead. Besides, Darrin Fletcher was plenty bad enough to be named worst all-time. He didn’t rack up errors like Munson, but he couldn’t throw anyone out to save his life. Fletch could hit the ball, so he survived as a DH for several years after his catching became unbearable. Unfortunately for Blue Jays fans, his announcing is just as bad as his fielding.
Outfield – Ben Grieve, (’97-’05) — I realize that this makes me sick, but I enjoyed watching Grieve play defense as much as any player in history. During the 2004 season I bought my tickets at Miller Park & Wrigley Field based on where Grieve was playing. Grieve reminded me of the short-lived SNL character Mr. No Depth Perception (played by Kevin Nealon). Inevitably, Grieve would break whichever way the ball wasn’t going, then run as fast as his lead legs would take him after the ball and finish with an awkward-looking swan dive. Worth the price of admission.
