7:50am: Rangers managing general partner and CEO Chuck Greenberg will no longer be part of Texas' managing team, according to Evan Grant of the Dallas Morning News (on Twitter). Greenberg upset a number of people as managing partner, but his undoing came when he bothered team president Nolan Ryan, according to Jon Heyman of SI.com, who confirms the news (on Twitter).
Greenberg's group took over the Rangers in August. He launched an aggressive pursuit of Cliff Lee this winter and later claimed that he out-foxed the Yankees in pursuit of the left-hander, who signed in Philadelphia.
