Fox and MLB Network to Collaborate on Pregame Show March 21, 2012, 3:31 pm Fox Sports" Saturday baseball 30-minute pregame show emanated from its Los Angeles studio for years. More recently, it was less a show than a 10-minute segment hosted from a game site by Chris Rose. Starting next month, Fox said Wednesday, the expanded half-hour program will be broadcast from the studios of MLB Network in Secaucus, N.J., where it will be hosted by Matt Vasgersian, with a group of analysts that will include Harold Reynolds, Kevin Millar, Mitch Williams and Eric Byrnes. The arrangement gives MLB Network a high-profile slot on broadcast television that will let it promote itself. Fox gets access to MLB Network's large corps of analysts and its studio cameras. The show will be a co-production of Fox and MLB Network. Vasgersian works for both companies. Fox has moved through a variety of hosts for its pre-game show since acquiring M.L.B. rights in 1996. Chip Caray, Keith Olbermann and Jeanne Zelasko preceded Rose.
