Daisuke Matsuzaka will most likely pitch in a rehab game at Ni-gun on April 14 against Hanshin at Naruohama. Whether he makes it into the game will depend on his condition and the weather. If he pitches, it will most likely be one inning.
Matsuzaka has not pitched in a game since March 16 (exhibition game against Seibu at Seibu Prince Dome).
