STOCKHOLM, Sweden (AP) _ Bjorn Borg's three-story villa was sold at auction for $1.9 million Thursday to satisfy some of the retired tennis star's debts.

Lars Nilsson, a hotel owner, said he would use the property in suburban Stockholm as a summer house.

Borg was reported to be $3.75 million in debt, the TT news agency said.

At one time, Borg's house was valued as high as $2.78 million.

Borg, a five-time Wimbledon champion, has had financial troubles since his attempts to build a clothing empire failed two years ago. He has been tuning up for at least a parttime return to the tennis tour.

NEW YORK (AP) - It was the Oscar Robertson decision in federal court that is credited with boosting free agency and sending salaries soaring in the NBA. Robertson is not too happy with everything the ruling has produced.

''The players are not worth the money they're getting,'' Robertson said Thursday night. He was among 60 retired sports heroes at the All Sports Hall of Fame Dinner to benefit the Boys's Club of New York.

Robertson blamed agents for what he called an ''absurd'' situation.

CALGARY, Alberta (AP) - Calgary Memorial Senior High School is fighting the Los Angeles Rams over the rights to a nickname.

Central Memorial senior high school has used the nickname ''Rams'' since 1908, but now the NFL team wants to gain exclusive North American rights to the name. Calgary lawyers have countered by filing a statement of opposition with the Registrar of Trademarks.

An attempt to negotiate shared use of the Rams name failed.

''They were taking the position that they weren't prepared to give us an offer of settlement, and we were instructed by the board to file a statement of opposition,'' said Martha O'Connor, a school board lawyer.

O'Connor said the Los Angeles team says it has used or made known the trademark in Canada and now wants formal protection under the Trademark Act.

She said the board will argue the trademark is not distinctive and NFL team should have known there had been prior use of the name.

ENFIELD, Conn. (AP) - Police believe that a ring of sports memorabilia thieves is responsible for three recent burglaries at collectible shops. The burglars went for baseball cards, not cash.

The owner of Matt's Sports Cards and Comics Shop said he lost $4,000 worth of sports cards and memorabilia a breakin last week.

Just north of the state border, in Springfield, Mass., someone stole $70,000 in sports cards and memorabilia from Bob's Hobbies and Collectibles earlier this month. And at the Sport Card Corner in West Springfield, about 175,000 cards worth a total of $50,000 were taken.

The burglaries occurred within three weeks of each other. At two of the stores, burglars broke in by entering a store next door and then smashing down an adjoining wall or door.

Investors with big money are now collecting sports cards once valued only by youngsters.

Last year, The Wall Street Journal rated baseball cards a better investment than precious metals or stocks, and advised investors to diversify.

MILAN, Italy (AP) - Ferrari is threatening to quit Formula One racing if the sport's governing body does not do something about actions that marred the last two world championships.

''Ferrari is ready to take drastic decisions ... including abandoning Formula One,'' Cesare Romiti, Fiat's managing director, said. ''We don't feel part of this world without rules.''

Romiti is the No. 2 man after chairman Gianni Agnelli at Fiat, the Italian automaker that owns Ferrari and its racing team.

Ferrari's chairman, Piero Fusaro, in a letter to the International Auto Racing Federation, protested the behavior of ''some drivers'' whose actions hurt the Italian team on the Grand Prix circuit.

The protests were touched off by last Sunday's collision between a McLaren- Honda driven by Ayrton Senna of Brazil and a Ferrari driven by Frenchman Alain Prost in the Grand Prix of Japan.

The collision knocked both cars out of the race and clinched the Formula One drivers' title for Senna.

Nigel Mansell's Ferrari was knocked out in a collision with a McLaren during the Hungarian Grand Prix last August.
