Manager Terry Collins and a trainer visited Matsuzaka on the mound following a two-out walk to Seth Smith in the first. Matsuzaka remained in the game.
After getting Chase Headley to ground to first base for the third out, the 33-year-old Matsuzaka slowly walked off the field. He received a handshake from Collins in the dugout before going into the Mets clubhouse.
Carlos Torres took over for Dice-K to start the second.
