Bo Jackson, the two-sport player, became a two-sport multimillionaire yesterday. Jackson, a loser in salary arbitration last winter, agreed with the Kansas City Royals on a one-year contract worth $2,375,000. He had been scheduled for an arbitration hearing today.

So was fellow Royals outfielder Jose Tartabull, and he too accepted a compromise -- amount undisclosed, but between the $1.75 million figure the club submitted and the $2.6 million he proposed.

Jackson's settlement came first, at 64 percent of the difference between the $2.7 million he sought and the $1.8 million Kansas City offered. When he lost last year, he had asked for $1,900,001 but had to take the Royals' offer of $1 million.

Jackson, 28, also is a running back with the Los Angeles Raiders and just finished the fourth season of a five-year football contract worth $7.4 million.

Limited by injuries to 111 baseball games in 1990, he hit .272 with 28 home runs and 78 RBI. He was hurt again in the NFL playoffs, injuring his right hip in the Raiders' 20-10 victory over Cincinnati on Jan. 13. It kept him out of the AFC championship game in Buffalo the following week and the Feb. 3 Pro Bowl.

Injuries held Tartabull to 88 games (15 homers, 60 RBI) last season, when he made $1.65 million.

Three other players settled yesterday and two had hearings. Milwaukee infielder Jim Gantner had the first hearing in Brewers history. He asked arbitrator Daniel Collins for $2 million; the team offered $1 million. Outfelder Cory Snyder asked first-time arbitrator Nicholas Zumas for $1.02 million; the Chicago White Sox offered $800,000.

In settlements, Cleveland right-hander Eric King agreed to $1.45 million, a $995,000 raise; White Sox outfielder Dan Pasqua agreed to $800,000, a $425,000 raise, and Atlanta outfielder Oddibe McDowell took $925,000, a $235,000 raise.

Boston pitcher Roger Clemens, meanwhile, denied the allegation by umpires union chief Richie Phillips that his record $21.5 million, four-year Red Sox contract includes money to pay any fines he might incur.
