Senga (calf/triceps) threw a 25-pitch live batting practice session Monday, Anthony DiComo of MLB.com reports.
Senga is not on the Mets' National League Wild Card Series roster after feeling tightness in his right tricep during a late-September rehab outing. However, the club is not ruling him out for the NLDS, should they advance. If Senga is added to the NLDS roster, he would be used in relief.
