Cubs chairman Crane Kenney said yesterday the team did not tell security personnel in the leftfield bleachers to crack down on fans who might boo or harass struggling outfielder Alfonso Soriano.

Fans had little reason to jeer him last night as he singled in the winning run in the 10th inning and the Cubs beat the visiting Los Angeles Dodgers, 2-1, to complete a three-game sweep.

On Sunday, Soriano dropped a fly ball in the ninth inning in Pittsburgh, helping the Pirates rally to a victory. One season-ticketholder told the Chicago Tribune that crowd control personnel told fans Monday they were instructed by supervisors to use a no-tolerance policy for anyone cursing at Soriano, or harassing him.

"The rules have not changed in the ballpark, which have consistently been booing is part of the game and anything related to booing. But profanity and anything racial is not allowed, regardless of where it happens in the ballpark," Kenney said before last night's game.

"What I'm hearing from our security staff is that the booing hasn't been significant nor has anyone been talked to. So I'm not really sure where this issue comes up."
