The Chicago Sun-Times (Chris De Luca) reports: Sources close to commissioner Bud Selig sounded an alarm this week during the annual general managers meetings: Forget about Mark Cuban buying the Cubs. Cuban, the Dallas Mavericks’ owner, was the fan favorite, the guy who liked to drink beer, watch the game from the bleachers and spend money. He was the most appealing bidder to Zell’s group, who knew Cuban could swing the quickest transaction for a team and ballpark that at one time figured to fetch $1 billion. Global financial crisis or not, baseball’s old guard plans to stand firm against letting Cuban into the club. ”There’s no way Bud and the owners are going to let that happen,” a Major League Baseball source said this week. ”Zero chance.”
