It's interesting that there are not any AL pitchers on the list, not even Justin Verlander (who is 11-1 since the All Star Game). Of course, the AL pitchers have to face a DH, but it's still striking that all of these pitchers are from the NL.
The Giants still have a shot at the playoffs, but it's likely that only 4 of them will be pitching in the postseason (Halladay, Lee, Greinke, Kennedy), but it is a good sign for the NL in trying to win another World Series (they've won 2 of the last 3 and have home field advantage again).
