Manager Jerry Manuel has confirmed that Martinez will return from the bereavement list to start against the Astros on Friday following an absence to mourn his father's passing.
Martinez has not pitched in a game since July 12, when he tweaked his right groin after four innings against the Rockies. He will join the Mets at Dolphin Stadium on Tuesday to throw an extended bullpen session, and could even throw an inning in relief, according to pitching coach Dan Warthen.
The Mets will cap Martinez at roughly 80 pitches against the Astros.
"I'll talk with Pedro probably [on Tuesday] and see what he thinks after the bullpen [session], and see how he feels," Manuel said.
Martinez, 36, has made only nine starts for the Mets this season, first battling a left hamstring strain, then dealing with his most recent groin pull. He left the team late last Wednesday to be with his family after his father's death in the Dominican Republic.
