Junior center David Robinson scored 31 points and blocked 10 shots, and sophomore guard Cliff Rees scored a career-high 19 points as Navy defeated William and Mary, 76-68, in a Colonial Athletic Association game tonight before 4,521.

Navy's seventh straight victory over the Indians improved the Midshipmen to 15-4 overall, 6-1 in the CAA. William and Mary, which lost all its starters from last season, fell to 4-12 and 0-6.

Navy equaled a season-high by shooting 61.4 percent (27 for 44) from the field.

Robinson, a 6-11 pivot man, scored 14 first-half points to help give Navy a 35-28 lead. William and Mary rallied, and Mark Boddy's layup at 10:55 closed the margin to 47-44. Rees, from Mount Hebron High in Ellicott City, Md., and forward Carl Liebert combined to scored 10 of Navy's 11 straight points as the Midshipmen took a commanding 58-44 lead. Rees, who had six points in the spurt, finished with nine-for-10 shooting from the floor.

William and Mary managed to make one last run, pulling to within eight, 68-60, on a basket by Tom Bock with 1:08 remaining.

But five throws by Robinson sealed the victory for Navy, which lost a first-place showdown with Richmond last Thursday and occupies second place in the CAA.

Robinson, who leads the nation in blocked shots with six per game, scored in the 30s for the second time this season and the 10th time in his career. His 20 free throw attempts were one shy of Navy's single-game record. His 15 free throws rank fourth on Navy's all-time list.

The Indians were led by junior forward Ken Lambiotte's 17 points and senior guard Scott Coval's 12. Richmond 74, American 59

CAA scoring leader John Newman scored 24 points and Steve Kratzer had a career-high 23 as the Spiders won their eighth straight game and the visiting Eagles, who committed a season-high 20 turnovers, suffered their fifth straight loss.

"Richmond is just too good of a team to stay with, considering the number of errors we made," said American Coach Ed Tapscott. "It a simple matter of execution. They did and we didn't."

American (7-10 overall, 1-5 conference) scored the first basket of the game but quickly fell behind, trailing by 10-4 three minutes into the game as Kratzer and Newman had two field goals each for Richmond.

The Eagles closed to 20-19 on Pat Witting's 15-footer with 8:57 left before intermission. But Richmond outscored American, 14-4, to take a 34-23 lead. Newman, who averages 22.8 points a game, had eight of those points.

The Spiders (16-1, 7-0) wrapped up the game early in the second half, launching a 10-0 run capped by Kratzer's turnaround to take the biggest lead of the game at 44-23 with 17:29 left.

American cut the lead to 11 with four minutes left when West made a 20-foot jumper to pull to 60-49.

The Eagles were paced by Frank Ross (second in CAA scoring with a 22.6 ppg average) with 20 points, Chuck West with 16 and Mike Sampson with 10. The Spiders got 10 points and 10 rebounds from John Davis. East Carolina 75, George Mason 67

Kurt Vanderhorst scored 17 points, Marchell Henry 15 and Leon Bass 14 as the Pirates withstood a second half-rally to win a CAA game before 3,600 at Minges Coliseum in Greenville, N.C.

George Mason is 9-9 overall and 3-3 in the league.

The Pirates (8-9, 3-3) led the Patriots by 33-21 at halftime by shooting 62 percent from the field compared to 37 percent for George Mason. Henry, a junior forward, completed a three-point play with 10:19 remaining in the game to give East Carolina its biggest lead, 52-38.

George Mason had an 8-2 run to pull within 57-52 when freshman Earl Moore of Cardozo High tipped in his missed shot with 5:20 remaining.

Freshman Kenny Sanders of McKinley Tech scored two free throws and two layups to pull the Patriots to 61-60 with just under two minutes remaining.

But the Pirates, who converted 17 of 20 free throws, scored the game's next four points, all from the foul line, to take a 65-60 lead with 1:16 remaining.

Sanders made a short jump shot and a free throw that pulled Mason to 65-63 with 58 seconds left. But the Pirates' Manuel Jones got free under the basket for two dunks to clinch the victory.

Mason, which made only five of 14 free throws, was led by Sanders' 20 points.
