Mets manager Carlos Mendoza announced Friday that Senga (calf/triceps) will start Saturday for Game 1 of the NLDS in Philadelphia, Anthony DiComo of MLB.com reports.

It's not a huge surprise that Senga will be on the roster, but Mendoza throwing him right into the fire in Game 1 is a bit of a shocker. Senga has started just one game all season for the Mets due to shoulder, triceps and calf injuries, and that start came two-and-a-half months ago. Mendoza didn't reveal how long he thought Senga could go Saturday, but he's not close to stretched out for a normal workload. The righty threw 15 pitches in a rehab start back on Sept. 21 and 25 pitches in a live batting practice session Monday. David Peterson and Tylor Megill are candidates to eat some innings after Senga in Game 1.
