Mitch Williams has been hired by the MLB Network, which goes on the air tomorrow in 50 million homes.

The former Phillies relief pitcher will be a studio analyst and will appear on "MLB Tonight," a live, nightly studio show and "Hot Stove," a live, nightly offseason studio show.

"Mitch's unique voice and perspective speaks for itself," MLB Network president and chief executive officer Tony Petitti said.

Last season, Williams, 44, was the postgame analyst on Comcast SportsNet's "Phillies Post Game Live." *
