Whether it was a bona fide Cub Occurrence or just that chronic issue of cramps, Cubs ace Carlos Zambrano was forced to leave the Cubs opener today in the top of the seveth after picking off Bill Hall at second base.
Zambrano, who has dueled Milwaukee ace Ben Sheets to a scoreless tie so far, favored his pitching hand after making the huge play for the second out of the inning. After manager Lou Piniella and trainer Mark O'Neal looked over Zambrano, Big Z left the game.
Last year's setup ace, Carlos Marmol, took over with a 0-2 count on Corey Hart and threw one pitch -- a called strike -- to finish the half inning.
No immediate word from the Cubs on Z's injury.
