The Mets and their new cable network, SportsNet NY, today will announce Keith Hernandez as lead analyst and Ron Darling as second analyst, The Post has learned.

Hernandez will join Met play-by-player Gary Cohen for around 100 games. Darling’s workload will be announced.

With Cohen moving from radio to TV, WFAN’s Met broadcast will also sound different. Howie Rose will slide into the lead play-by-play role and be joined by former Phillie radio-caster Tom McCarthy.
