What pitcher has had the better past couple starts? James Shields or Daisuke Matsuzaka?

Daisuke has been better in my opinion. He only allowed one hit in both games, something he has never accomplished. His fastball painted the black of the plate and his sinker/change had incredible movement. He was in control and locked in. He also has the brighter future. Things can only get better for Matsuzaka, who has been an enigma ever since he joined the Sox. He has looked better than he ever has. I know he can be very erratic, but I say he turns it around this year, and establishes himself as a sold #5 or #4 starter.
