1. Ubaldo Jimenez has performed AMAZINGLY, especially for a pitcher who plays at Coors Field. He is 5-0 with a .79 ERA. The guy already has a complete game shutout and 31 strikeouts. He is, right now, the best starting pitcher in baseball. He has dominated in every game, even against top ranked (in terms of Runs) teams like the Brewers and Diamondbacks. Of course he has balanced that out with starts against the (not as lowly as usual) Nationals and Padres and Braves.
2. Mike Pelfrey has been pitcher 1a. for the start of the season. Being a Met he is partial to my heart so I would love to put him over Ubaldo but just couldn't do it. Mike started out the season 4-0 with a league leading .69 ERA. Him giving up runs is as rare as France not pussying out in a fight. He's only given up 2 runs in 26 innings pitched. He even got his first career Save during the 20th inning of that marathon Mets-Cardinals game. The only gripe against Mike is he has not gone as deep into games as Ubaldo.
^ Pelfrey is so Cool
