Pitching coach Dan Warthen said Friday that Matsuzaka will be capable of throwing 100 pitches on Sunday, despite moving to the bullpen at the start of the season.
"Throwing 100 pitches, it shouldn't be a problem," Matsuzaka agreed (ESPN, May 23). "It's something I know how to do. I don't really want to think too deeply into it. I just want to go into the game and do my role."
Matsuzaka said he understands that Sunday is a one-time thing, and that he will return to pitching in relief Monday.
Arizona will reportedly promote a starting pitcher from the minor leagues.
