Steven Matz tossed 80 pitches over five innings in an instructional league game today in Port St. Lucie, consistently throwing his fastball at 93-94 MPH. After the outing he said his back felt fine, though he—and the Mets—will have to see how he feels on Friday morning before deciding if he'll be added to the NLDS roster.

Following a discouraging week that featured a depressing combination of bad news and no news regarding Matz's health, he threw a successful bullpen session on Tuesday and now appears to be on the upswing. With Juan Uribe already left off the NLDS roster, the Mets would love to have Matz with them to start a potential Game 4 against the Dodgers at Citi Field. That game would be on Tuesday, October 13, giving Matz another four days after tomorrow to prepare for his start.

For what it's worth, Eric Campbell has no doubts about Matz's availability for the playoffs:
