CHICAGO (AP) _ Foes of night games at Wrigley Field are postponing until April any attempt to ban the sale of alcoholic beverages in the precinct that takes in the Chicago Cubs' park, leaders of a protest group said Monday.

Mike Quigley, vice president of Citizens United for Baseball in the Sunshine (CUBS) said the group now plans to use the threat of voting the precint dry as a means of obtaining concessions from the city and the Cubs management.

Quigley said CUBS volunteers have obtained the support of more than the 162 precinct residents needed to put the local option referendum on the Nov. 8 ballot, but the group has decided not to file at this time.

''We can use it as leverage now,'' Quigley said several hours before the first night game at the historic ballpark.

Quigley said CUBS' true aim is not to ban alcohol sales at Wrigley Field and the 10 taverns and liquor stores in the precinct, but to obtain a cut-off curfew on how late night games will be able to run and a guarantee that there will be no more than 18 night games a year.

''We want guarantees that should have been in the original ordinance allowing night games,'' he said.
