When Posnanski describes it based on "making the play" or not, is the throw weighted differently than the catch? For example, if a 3B makes a spectacular catch on a grounder down the line but botches the throw, is that missed play calculated differently than if the player had simply missed the catch? In the former situation it would seem that the player should get credit for the catch even though an error was made on the throw. Just wondering.

It's just a scaling factor to have OBA easily comparable to OBP. Thus, to convert back to wRAA, you must first scale it back down (divide by 1.15) to convert to the actual runs above average.

Remember than pitcher Win/Loss records are not entirely up to the pitcher but have a lot to do with the team behind them. Would he have won 16 games? Probably not, but that's not a testament to his ability, but rather the team's ability to help him out on defense and score runs.

I may be off slightly on this number, but, for example, I read that Justin Verlander had a WAR of 8, impressive I guess. So that means he is eight wins better than a minor league or waiver wire player. Really? So your top minor league pitcher is going to win 16 games? (Verlander won 24). Hardly. Maybe I'm confused about what WAR really means, but I can't believe that someone who won the pitching triple crown with that record is only eight games better than a replacement. Set me straight. By the way, I am not anti-saber. I've enjoyed reading Bill James since the early 1980s and believe much of what he writes. I’m still unconvinced about WAR.

]]> Comment on K% and BB% by jimbo http://www.fangraphs.com/library/index.php/offense/rate-stats/#comment-61108 jimbo Wed, 18 Jan 2012 19:22:11 +0000 http://sabrlibrary.com/?page_id=251#comment-61108 Works both ways. If you take those player scenarios and instead think of it as two seasons for the same player...shouldn't there be improvement shown in K% in year two? They struck out in 200 at bats, but didn't strike out in 500. The fact they went from 200 walks to 0 should be handled outside of K% imo. Either way you still need to keep BB% and K/BB in view.

I know exactly what you mean that every geek thinks their Bill James. To be honest I have never heard any human being, even at Yankee Stadium, (in all three of them) where I have been watching BB games since the 1950s say Mariano Rivers is the best pitcher ever. As a matter I have never any say he was the best Yankee pitcher ever. Just to nit pick. Have to nit pick to get ready for pitchers and catchers. Even after the Giants huge win yesterday when the Giants got revenge for 1962. In 2008 we got revenge for 1961. To: John Ogrin. I know exactly what you mean that every geek thinks their Bill James.
