CINCINNATI (AP) _ Officials of the Association of Tennis Professionals Championship tournament have presented a check for $155,000 in proceeds from the 1985 event to a Cincinnati pediatric hospital.

Tournament director Paul M. Flory presented the check to Dr. William K. Schubert, president of Children's Hospital Medical Center. Flory said the donation boosted the ATP Championship's contributions to the hospital to $1.01 million since 1974, when the event was known as the Western Tennis Championship.

The event has raised more money for a charitable cause than any other professional tennis tournament, according to the Association of Tennis Professionals, which sponsors the Cincinnati-area tournament each August.

''These gifts to Children's give all of us who are involved with the event a great feeling of accomplishment, knowing that they contribute to the work of this outstanding institution,'' Flory said in presenting the check during a Cincinnati news conference Friday.

The ATP tournament is played annually at the Jack Nicklaus Sports Center, 20 miles north of Cincinnati. The 1986 tournament will feature a 64-player field of tennis pros, will offer $375,000 in prize money and is to be played Aug. 18-24. The singles champion will be paid $48,000 and the winning doubles champs will split $18,000, Flory said.

Boris Becker of West Germany, the Wimbledon singles champion, won the singles title of the 1985 ATP Championship. Anders Jarryd and Stefan Edberg won the tournament's doubles title.

HONOLULU (AP) - Ray Perkins, preparing his University of Alabama football team for the Aloha Bowl, said he would like to see the four major New Year's Day bowls serve as first-round games leading to a ''College Super Bowl.''

Perkins said the absence of a playoff system ''bothered me for years - going all the way back to my playing days at Alabama.''

Perkins said he has been an advocate of some kind of playoff system since 1966, when he was a senior receiver on an Alabama team which finished 11-0 but finished third in the national poll behind Notre Dame and Michigan State, which had played to a season-ending 10-10 tie.

''That was enough to convince me college football needed another way of deciding its national championship,'' Perkins said.

''When you look at what the playoffs and the Super Bowl have done for pro football, you're not being realistic if you don't think the same thing couldn't happen to college football, which I think is the greatest game on earth,'' Perkins said.

SEOUL, South Korea (AP) - The ground was broken Saturday for the construction of an international broadcasting center to be used during the 1988 Summer Olympics.

The state-run Korea Broadcasting System, host broadcaster for the games, said it will finance the construction of the nine-story center, to be completed by May 1988 on Yoido, an islet in the Han River not far from Olympic stadiums.

The center will be used by foreign as well as domestic television and radio networks covering the Games.

Seoul Olympic organizers said the center will be equipped with telecommunicat ions devices and feature international network offices, studios, control areas, conference rooms and equipment leasing services.

After the games, the KBS plans to use the structure as its own broadcasting center.
