Villanova and Maryland, the undisputed powers of Eastern track, renew their torrid rivalry today and Sunday in the IC4A Championships at Philadelphia.

A year ago, Maryland scored 98 points and lost by one to the Wildcats. This time it is likely to take more than 100 to claim victory.

Villanova is riding a high tide of success, having captured IC4A titles in cross country and indoor track, as well as the NCAA indoor track championship.

Maryland always performs better outdoors, because of its field-event strength, and the Terrapins rate as no worse than cofavorites.

Renaldo Nehemiah, the world's greatest hurdler, will shun his speciality - he suffered his only defeat of 1979 in the indoor IC4A when he ran around a hurdle - to run the 100- and 200-meter sprints. He also is available for relay duty.

Other terrapins with good chances for individual titles include Chris Person, 400-meter hurdles; Ian Pyka, shot put; Bob Calhoun, long jump; Dennis Ivory, triple jump; Paul Dubyoski, javelin, and Greg Robertson, 110-meter hurdles.

Villanova needs piles of points from Don Paige, 800 and 1,500; Sydney Maree, 1,500 and 5,000, and Amos Korir, 10,000 and steeplechase.

Maryland is counting on neighboring Georgetown to dilute Villanova's point potential in the middle distances.

The Hoyas have two outstanding 800 runners in Jim DeRienzo and Aubrey McKithen, while John Gregorek should do well in the steeplechase and Bill Ledder is a potential 1,500 finalist. Philip Reilly also will contest the 1,500 with Keith Royster in the 400 hurdles.

Kevin Byrne, the Hoyas' fine 1,500 man, will miss the meet because of an inflamed Achilles' tendon.
