Another reason many people are misguided in to thinking Jason Bay is a good defender and not..you know..bottom 5 in the entire league.Quote:
I assigned every player a position based on where he played the most innings, and all stats count toward that position.
There were five players who made no errors but tallied three or more Web Gems.
Here, you see some hits and some misses. Sizemore and Vizquel are, by all accounts, excellent defensive players. David DeJesus and Austin Kearns are average. And then there’s Jason Bay. For the Jason Bays of the world, I submit to you the Gary Matthews Jr. effect. Matthews, you may recall, made a stupendously phenomenal catch a couple years ago that was replayed and analyzed like the Zapruder film. His defensive reputation was built off of one play. And you can't point out the number of errors for outfielders to disprove the reputation, since outfielders don't make errors. Anyway, I hope nobody signs Jason Bay to a GMJ-type contract.Code:Name Position Web Gems

Why did I put basically the entire article in quotes? Mainly because I was bored :|Quote:
I would venture that Web Gem percentage correlates with UZR not because Web Gems assess skill, but because they track the most influential plays. The average runs saved per play defensively is .8, a tick higher than that for outfielders. I’d venture that most Web Gems are plays made no better than 10% of the time on average. So for every web gem, you can probably attribute at least half a run to that player's value.
Tangotiger’s invaluable Fans' Scouting Reports finished balloting this week. I’m guessing that Web Gems will be even more influential in shaping the fan’s opinion than in swaying any defensive statistics. Here, I'll report the correlation coefficients between Web Gem percentage and several ratings from the FSR.
You see that fans are likely more influenced by spectacular plays made by infielders than by outfielders. Since such a significant portion of a third baseman's fielding ability is making the remarkable play, Web Gems correlate well for 3Bs in both UZR and scouting reports. The only surprising result I found is that there isn't a positive correlation between throwing strength from right and center fielders and Web Gem percentage. I figured a lot of outfield Web Gems would be a result of throwing strength. Perhaps throwing strength isn't strongly correlated with outfield assists. Something to look into.Code:Average Reactio Acceleration Velocity Hands Throwing Strength

And since the Gold Gloves were announced this week, I'll leave you with a table of each Gold Glovers relevant statistics as well as the guys at each position who I consider to be the best not to have won the award. Adam Jones over Franklin Gutierrez really stands out as a poor selection.
