Major League Baseball's official press release:

The Chicago Cubs have placed right-handed pitcher Carlos Zambrano on the disqualified list, effective immediately.

The disqualified list includes a period of 30 days without pay and no activity with the ball club. During this time, Major League Baseball and the Major League Baseball Players Association will discuss recent statements attributed to Zambrano regarding his baseball future.

Zambrano was ejected from last night's start in Atlanta after allowing eight runs on eight hits in 4.1 innings, matching the franchise record for five home runs allowed in an appearance. He was charged with the loss in Chicago's 10-4 setback. Zambrano is 9-7 with a 4.82 ERA (78 ER/145.2 IP) in 24 starts for the Cubs this season.
