David Page, news director at WRQX-FM (107.3), got into hot water his first day on the job Monday by devoting his commentary to why Washington shouldn't want a baseball team. Dozens of listeners called to say that Page had struck out, and the station aired an apology on Tuesday.

"He said baseball was having problems with the outrageous salaries, attendance problems, prima donna players and drug usage, and he said, 'Let's be smart and ban baseball in D.C.,' " explained program director Randy Lane. The 10-second apology, read by Lane, said, "Many of you were offended by some comments made by David Page, our new news director yesterday morning . . . We apologize." Lane said that the station received about 50 calls and that there also was a lot of mumbling in the halls around WRQX, which shares a building with WMAL-AM (630), a leader of the drive to bring a baseball franchise here in 1987.

Page, who describes himself as a "polarizing personality" who has prompted station apologies in previous jobs, said he had learned one lesson: "Apparently people are supersensitive about baseball." Page has worked for stations in Memphis and New Orleans and as an editorial assistant for CBS Radio News in Paris. Though he had been hired for his "controversial and biting" style, Page said he wasn't upset about the apology. "I thought it was a good idea. I think that given the sensitivity . . . they should make it clear that what I say is not what everyone else thinks."

In addition to the commentary at 7:40 a.m., Page is anchoring the news during the Jim Elliott and Scott Woodside show, the noon news and a Sunday night talk show, "Live Line," from 11 p.m. to 3 a.m. Page said the station had not asked to see his copy in advance or given him any guidelines for topics. "I just want him to be responsible for what he says. I want him to have his facts together," Lane said. Other Assignments
