Pitching staff

I shored up my pitching staff by adding Bronson Arroyo of the Reds and Gil Meche of the Royals. Arroyo was filthy good against the Twins yesterday. Meche is a little more questionable because he pitches for Kansas City, but he does pitch twice next week. Jon Lester is available, but I am concerned about his uneven performance, particularly his performance in the Japan game.
