Expansion Seen

Further expansion in professional football, baseball and basketball was tabbed yesterday the likely major trend of the new sports year.

Fifty-five of the 105 sportswriters and broadcasters participating in the annual Associated Press poll predicted that the firming up of new leagues and the addition of franchises to already-operating circuits would be the most important development in 1960.

Fourteen voters put the finger on bidding between the National and American football leagues for college players while nine cast their ballots for an increased swing to participation sports such as bowling, hunting and fishing, and boating.

Other predicted trends or developments were: more trouble for baseball's minor leagues, inter-league play in big league baseball, further bickering over sports legislation, and spectacular Olympic Games in Squaw Valley, Calif., and Rome.
