The University of Pittsburgh fired football coach Foge Fazio yesterday and immediately sought a replacement with major college credentials.

"We didn't reach our objectives," Athletic Director Edward Bozik said. "We have concluded that the long-term interests of our football program would be better served if a coaching change were made at this time."

Pitt was 25-18-3 in four seasons, including 5-5-1 this season, under Fazio. Pitt lost, 31-0, to top-ranked Penn State on Saturday night, and Bozik said "there was a chance" Fazio could have kept his job if his Panthers had won.

Bozik said a preliminary list of replacements include several men who will coach in bowl games, but he refused to identify them. "We're looking for someone with Division I-A experience as a head coach, but we wouldn't necessarily rule out taking someone from the pros."

Fazio, a former Pitt player and assistant coach who was unable to match the successes of predecessors Jackie Sherrill and Johnny Majors, said he has not decided whether he will continue coaching. "I'm not going into a coffin," he said. "I'll still be around. I know I'm a good football coach and a good recruiter. I just don't know what I'm going to do yet." . . .

Jim Garrett, the Columbia football coach who had called his players "drug-addicted losers," resigned after the Lions completed the worst season in their 116-year history. The Lions went 0-10 this year and ran their losing streak to 21 games over a three-year span. Garrett succeeded Bob Naso last December. BASEBALL

Chicago White Sox shortstop Ozzie Guillen, 21, was named American League rookie of the year in voting by the Baseball Writers Association of America. Guillen committed 12 errors in 150 games last season, the fewest of any regular AL shortstop, and hit .273.

He came to the White Sox last Dec. 10 in the seven-player deal that sent right-handed pitcher LaMarr Hoyt, the 1983 Cy Young Award winner, to San Diego along with two minor leaguers for pitcher Tim Lollar, infielder Luis Salazar, Guillen and a minor leaguer.

Guillen received 16 of a possible 28 first-place votes -- allotted two apiece among BBWAA members in each of the 14 American League cities -- for 101 points. Ted Higuera, a left-handed pitcher from the Milwaukee Brewers, was second with nine first-place votes and 67 points . . .

Both the Kansas City Royals and St. Louis Cardinals earned record shares for their seven-game World Series, according to the commissioner's office.

The winning Royals will get $76,341.71 for each of 31 full shares voted by the players. That topped the previous record of $65,487.70 set in 1983 by the Baltimore Orioles. The losing share will be worth $54,921.76 for each Cardinal, breaking the mark of $44,473.31 set by the Philadelphia Phillies, also in the 1983 Series. The Cardinals also voted 31 full shares . . .

Baseball has decided to change the format for All-Star Game balloting, but a spokesman for the commissioner's office said that fans will continue to vote for players. The new format results from the end of an association with the Gillette Co., which has conducted the voting since 1970, when it was restored to the fans after 13 years of voting by the players.

Advertising Age magazine reported that the change was made when Gillette was unwilling to come up with additional money. "Selections for the summer classic are expected to be turned over either to players or sportswriters," the magazine said. TENNIS

The four seeds who got their matches in between two rain delays on the opening day of the Australian Open in Melbourne all won.

Seventh-seeded Manuela Maleeva, 18, of Bulgaria, 10th-seeded Catarina Lindqvist of Sweden, 11th-seeded Barbara Potter and 16th-seeded Katerina Maleeva -- Manuela's 16-year-old sister -- all won first-round matches as only 14 matches were completed. The rain postponed all of today's scheduled matches until Wednesday . . .

John McEnroe, scheduled to play later in the week, had an incident at his Melbourne hotel lobby in which he allegedly shoved an Australian reporter and spat at a photographer, who spat at the tennis star in return. McEnroe had been asked about rumors that he had married his girlfriend, actress Tatum O'Neal. McEnroe denied the rumors. The reporter, Geoff Easdown, said he did not plan to take legal action against McEnroe. JURISPRUDENCE

In New Orleans, a former Tulane University basketball player and two students sentenced for their part in a point-shaving scheme escaped prison terms but were ordered to give their gambling proceeds to charity.

Bobby Thompson, 22, a senior guard who pleaded guilty to one count of conspiracy to commit sports bribery, was fined $2,000, given a two-year suspended sentence, placed on probation for five years, ordered to put in three months of community service and make restitution of $4,000 by donating it to the United Way. Two others received a two-year suspended sentence and five years probation. Mark Olensky of Fair Lawn, N.J., was ordered to pay $5,600 to the city's food distribution program, and David Rothenberg of New Wilton, Conn., was ordered to pay $5,200 to the Salvation Army. PRO FOOTBALL

Running back Curtis Dickey, hobbled by injuries much of the past two seasons, was cut by the Indianapolis Colts. Coach Rod Dowhower cited Dickey's attitude as the prime reason for the move. "We have givers or takers and winners or losers," Dowhower said. " . . . With his attitude to practice, he didn't give what he had to for this football team . . . I'm not a babysitter."
