Forward Charles Jones, who had his finest overall performance as a Washington Bullet in a 127-121 victory over Portland Wednesday night, was rewarded with a multiyear contract yesterday. The 6-foot-9 Jones, a free agent, was in the final day of a second 10-day contract with the Bullets when he signed the long-term agreement.

Jones, an eighth-round draft choice by Phoenix in 1979, received tryouts from Portland, New York, Chicago and Philadelphia and spent two years in Europe before signing his first 10-day contract with the Bullets.

"The team had been struggling a little and I wanted to do what I could to help," said Jones, the younger brother of Caldwell (Chicago Bulls) and Major Jones (Houston Rockets). "I don't worry so much about my minutes. When you get a chance to play, you try to get in the flow as quickly as you can and do your part."

Jones played an important role in the Bullets' double-overtime victory over the Trail Blazers. He played 31 minutes and had six points, 13 rebounds, four blocked shots and four steals. Since joining the Bullets, he has averaged 15 minutes, four points, four rebounds and just under two blocks per game.

"I had been playing more and more recently," Jones said, "and I think they must have confidence in me. I'm primarily a shot blocker and they aren't looking for a lot of points from me. I think I'm starting to fit in real well."

After his showing against Portland, Jones might be one of the first players off the bench tonight when Washington plays host to the Seattle SuperSonics at Capital Centre at 7.

The game has an earlier than usual starting time because of a basketball game featuring members of the Washington Redskins against a team from the San Francisco 49ers that is scheduled to begin immediately afterward.

Washington (32-31) is battling New Jersey (32-31) for third place in the Eastern Division. Seattle, a disappointing 26-37, might be without forward Danny Vranes (sore finger) and guard Gerald Henderson (bruised thigh).

The Sonics, who defeated Washington, 109-94, on Gus Williams' homecoming night in Seattle in February, look to Tom Chambers (20.7 points) and Jack Sikma (19.1 points, 10.9 rebounds).
