Dave Bonner scored 23 points and Chuckie Jackson tossed in 22 last champion Dunbar to a 90-71 victory over Gwynn Park in boys basketball at the Prince George's school.

The Crimson Tide (4-2), rebounding from an eight-point loss Monday to Mater Christi of New York City, made 20 of 33 shots in the first half and connected on 57 percent of its 68 attempts in the game. Gwynn Park (4-2) took 68 shots but made just 30 (44 percent).

"We beat them on the boards, which allowed us to get down the floor to take easier shots," said John Walker, Dunbar's assistant coach who is guiding the team while the head coach, Joe Dean Davidson, recuperates from a heart operation.

"Chuckie is our instant offense. He can score when you need a big play or just lead the flow of the offense," Walker said.

Bonner and Jackson, both 6-4 forwards, had 10 first-half points each as Dunbar built a 21-point lead.

Gwynn Park played without leading scorer Moochie Clark, suspended by Coach Larry Gandee for five games for disciplinary reasons.

The Crimson Tide, which outrebounded Gwynn Park, 27-20, moved to a 20-12 first-quarter lead on 10-of-14 shooting while Gwynn Park sank just five of 16.

Gwynn Park closed within five early in the second quarter, but the Crimson Tide responded with six consecutive baskets, three each from Jackson and 6-5 Anthony Jones, to open a 32.17 lead. By halftime the Dunbar margin was an insurmountable 56-35.

The Tide cooled off to start the second half, except for Jackson. He hit four long jumpers to negate Jeff Adams' six third-quarter points for Gwynn Park. Dunbar led by 14 at the end of the period, 65-51.

Adams, who led all scorers with 26, and teammate Joe Wood took the ball inside in the final quarter to help bring the Yellow Jackets within 72-59 with four minutes to go. But Bonner, who grabbed eight rebounds, made a three-point play and Jackson hit a jumper to end that threat.

In Macon, Ga., Bob Donohoe of St. Hohn's of D.C. hit a jump shot with six seconds remaining to lift the Cadets over Northeast of Macon, 61-59, and into the title game tonight of the Tome Porter Classic.
