Guard Ricky Pierce, after weeks of trying to get the Milwaukee Bucks to renegotiate his contract, said yesterday he was pleased to learn they traded him to the Seattle SuperSonics for guard Dale Ellis.

"It's part of business," Pierce said. "I'm not worried about it. I'm very happy to be with Seattle. My future was not going anywhere with the Bucks. They didn't want to compensate me. Getting out was the best thing for me," he said.

The deal depends on each player passing his new team's physical examination. The Bucks said they expect Ellis to be available for Milwaukee's game Sunday at Orlando.

Ellis, 30, traded by Dallas to Seattle in 1986, was averaging more than 15 points a game this season. The 6-foot-7 guard missed the first 17 games because of a foot injury.

He averaged more than 23 points per game in his previous four seasons.

Pierce, 31, acquired by Milwaukee in a 1984 trade with the San Diego Clippers, led the Bucks this season with a 22.5 scoring average. The 6-4 guard received the NBA's sixth man award in 1987 and 1990 and was named to the last weekend's All-Star Game.

In other moves: The Pistons signed guard John Long for the rest of the season after his two 10-day contracts expired; the Heat placed guard Jon Sundvold on the injured list and activated forward Terry Davis; and the Spurs signed guard Clifford Lett to a 10-day contract.
