Worst outfield arms?

Keith Woolner at Baseball Prospectus just came out with a short piece on the worst outfield arms in baseball. Interesting idea, but his methodology leaves a little to be desired. Woolner compares which outfields did the best at keeping runners from scoring from second on a single. He compares teams' success compared to the league average, which allows runners to score 60% of the time.

The good news? The Red Sox don't make the list. The bad news? The numbers aren't park-adjusted, so Fenway's short left field may be skewing things in our favor.

Here's the worst:
