Scott Skiles scored 20 points and Vernon Carr added 18 to lead Michigan State to an 87-61 college basketball victory over George Washington tonight.

Michigan State (5-0), which uses 6-foot-1 senior Skiles, 6-6 junior Carr and 6-2 junior Darryl Johnson as guards, got off to an 8-2 lead by hitting its first four jump shots. The Spartans led by 18-4 with 14 minutes left in the first half and built their advantage to 40-25 by intermission as the Colonials (3-2) could not effectively execute their offense against Michigan State's aggressive match-up zone.

The Spartans shot 65.5 percent from the floor before intermission, hitting 19 of 29 shots. Skiles had 10 points in the first half and Johnson and Carr had eight each.

Leading by 58-35 with 15:58 to go, Michigan State went on a 19-7 tear over the next six minutes to take a lead of 67-42.

Michigan State's bigger front line outrebounded George Washington, 42-27. The Colonials, whose tallest player is Moti Daniel at 6 feet 6, use 6-foot-5 Steve Frick at center. The Spartans' front court consists of 6-foot-8 center Barry Fordham (seven rebounds) and 6-foot-8 forward Larry Polec.

Troy Webster led George Washington with 22 points and Daniel had 18 points and eight rebounds.
