Daisuke Matsuzaka struck out five in three hitless innings for the Mets. Called up from the minors last week, Matsuzaka was pitching on consecutive days for the first time in the majors. He made his second career relief appearance in his season debut Saturday night.
"I told him that I could go. When it went into extra innings, I knew I'd have to pitch some," Matsuzaka said through a translator. "This is my role for the time being, so I'll do my best."
