First baseman Fred McGriff and the San Diego Padres agreed last night to a four-year, $15.25 million contract with an option for 1995 that could make the package worth $19 million.

McGriff became the 37th player to get $3 million a year or more. The annual average value of $3,812,500 is the fifth highest in baseball.

The Padres would not confirm a deal had been made. They said an announcement will be made today.

McGriff made $1.45 million last season with Toronto. He had been asking for $3.3 million in arbitration and San Diego had been offering $2,225,000.

McGriff batted .300 last year with 35 homers and 88 RBI. At the winter meetings, he and Tony Fernandez were traded for Joe Carter and Roberto Alomar.

Dodgers right-hander Tim Belcher lost his arbitration hearing and will double his salary instead of tripling it. Belcher, who made $450,000 last season, was awarded $900,000; he requested $1.35 million.

Owners have won four of seven arbitration cases. Right-hander Doug Drabek and Pittsburgh argued their cases yesterday.

California outfielder Luis Polonia tripled his salary when he and the Angels settled at $770,000.

Free agent outfielder Glenn Wilson agreed to a one-year contract with Atlanta and Seattle invited catcher Bob Boone, 43, to spring training.

Meanwhile, Richie Phillips, executive director of the Major League Umpires Association, says he fears a spring training lockout of umpires despite contract negotiations that he describes as on schedule.

"Some owners feel they need to get a win," he said. "They want to send a message to the umpires that just because we gave {big contracts} to the players, don't think we'll give it to you. There are teams with $30 million payrolls who will fight over who pays for the fertilizer in training camps. They're saying: 'It stops here. We draw the line with the players.' "

Robert Kheel, representing Major League Baseball in negotiations, could not be reached to comment.

The umpires' contract expired Dec. 31 and Phillips said negotiations are progressing on schedule. Umpires will meet Feb. 25-26 in Orlando, Fla., where Phillips will brief them. He said that even without an agreement before spring training, he would advise the umpires to continue working.

"I see no reason for a work stoppage," he said. "I am optimistic that we can have an agreement before the start of the season."
