In his first TV gig since leaving Current TV, Keith Olbermann has been tapped by Turner Sports as host of TBS’ Major League Baseball postseason studio show, joining analyst and Hall of Famer Dennis Eckersley. Additionally, Ron Darling, who joined TBS as an MLB analyst in 2008, has inked a long-term extension. And Hall of Famer Cal Ripken, Jr. will transition from the studio to the broadcast booth full time this postseason. Ripken, who primarily has served as a TBS studio analyst for the last six years, will join Ernie Johnson (play-by-play) and Darling as a three-man commentator team throughout the 2013 MLB Postseason, including the network’s coverage of the Division Series and exclusive telecast of the National League Championship Series.
