FALSE.
He has been accountable for a lot of runs this year with his costly errors.
You continue to surprise me. Maybe the next thing I read from you will be "Nook Logan for best hitter"
I wouldn't be so quick to dismiss Zimmerman's defense. The error stat is one of the worst in terms of conveying meaningful information, right down there with RBI's and average at the bottom. What's wrong with errors? All other factors being equal, the guy who gets to the most balls will have the most errors, and yet that player would be your best defender. Take player A and Player B. Both players have a 5% error rate, but player A fields 500 balls, and player B fields 400 balls. Player A will have 25 errors vs. 20 for Player B, but A fielded 475 successfully while B fielded 380 successfully.
So the problem with errors, is, it focusses on a very narrow subset of overall fielding. Zimmerman leads all third basemen in chances. He's got phenomenal range. Sure, the errors are costly at times, but he's making errors on plays that other guys don't even get to. You simply can't focus on a small subset of performance and ignore the largest, most important dimensions.
