Volquez has gotten ridiculous run support this year (only one game less than 8 runs), but he's also pitched excellently to go with that support. So far this year, he hasn't allowed more than one run in an outing, but I suppose it is easier to pitch when you've got a comfortable lead. He still needs to cut down his walks, but that's really the only nit to pick with him so far. At this point the Wagon just keeps on rolling.
Hudson has been solid this year for the Braves, but he's only made it through 3 innings in two different starts. As a team, the Reds have hit him decently in the past, but they have not been able to beat the Braves during a Hudson start. The main reason for that has been the three starters that opposed Hudson, namely Eric Milton, Joe Mays, and Phil Dumatrait. Hopefully Volquez will put up more of a fight.
