Thursday Night Baseball is the title of a presentation of Major League Baseball on cable and satellite channel MLB Network, that premiered on April 9, 2009. Longtime NBC Sports broadcaster Bob Costas is one of the play-by-play voices of the broadcasts. Matt Vasgersian also does play-by-play on some games. Al Leiter, Joe Magrane, Dan Plesac, Harold Reynolds, Mitch Williams and Jim Kaat provide color commentary. The new network produces 26 non-exclusive live games a year on Thursday nights. Since one or both teams' local TV rights holders also carry the games, the MLB Network feed is subject to local blackouts. In that event, the cities in the blacked-out markets will instead see a simulcast of another scheduled game via one team's local TV rights holder.
