Matz is on track to start Game 4.
The Mets are satisfied that Matz's back spasms are behind him. He tossed an 88-pitch simulated game on Thursday in Port St. Lucie, Florida. It was his first game-type setting since Matz faced the Cincinnati Reds on Sept. 24.
Matz is expected to join the team in New York to avoid having two unnecessary cross-country trips for games in which he is not scheduled to pitch.
The 25-man roster:
Game 1 starting position players
The Mets also have seven reserves continuing to work out in case they are needed as an injury replacement or for future rounds: Gilmartin, Logan Verrett, Carlos Torres, Bobby Parnell, Eric Campbell, Anthony Recker and Eric Young Jr.
