Matz (side) completed a bullpen session Tuesday at Citi Field, MLB.com reports. "I think we've been encouraged over the last couple of days," General manager Sandy Alderson said. "Things have improved. Certainly, today was a step forward."

EDGE Analysis

Now that the bullpen session is behind him, Matz has just one more hurdle to clear -- a simulated game Thursday -- to solidify his spot on the NLDS roster. If Matz makes it through the live session unscathed, he will likely start Game 4 against the Dodgers on Oct. 13. Sean Gilmartin would likely make the roster if Matz is deemed unavailable, while Jacob deGrom would be an option to start Game 4 on short rest.
