The Chicago White Sox, whose home is the oldest in the major leagues, Friday responded to news of the Illinois Legislature's plans to build a new stadium - thereby averting the team's threatened move to Florida - with mixed reactions.Members of the American League team whose 78-year-old Comiskey Park home is the oldest park in the major leagues, expressed a range of surprise, disappointment and apathy.

"It was a surprise," said White Sox Manager Jim Fregosi before the team's contest against the New York Yankees. "Everybody said it (he vote to build a new stadium) wasn't going to take place. But they (awmakers) voted the right way and that's great. I think all the ballplayers are excited about getting a new ballpark."

Nine-year veteran Harold Baines, the most senior member of the White Sox,was less than enthusiastic about the 60-55 House vote to approve the deal, which still needs the approval of the White Sox board of directors.

Baines doubted whether any current White Sox would be around long enough to actually work in the new stadium, which is scheduled to be completed by 1992 at a site just across the street from Comiskey.

Carlton Fisk, who unlike Baines lives in the Chicago area during the offseason, expressed disappointment that lawmakers had to work up to the deadline of the summer legislative session before deciding whether to let the White Sox move to Florida.
