Sophomore Carlos Yates scored 27 points and freshman Rob Rose had 22 last night as George Mason welcomed Monmouth College to the world of Washington-area basketball with a 91-71 beating at the Patriots' gym in Fairfax.

Yates' performance was no surprise; the Flint Hill Prep product was the Patriots' leading scorer a year ago. But Rose, a 6-foot-5 forward from Rochester, N.Y., had averaged only 3.5 points in his first two games and is listed in the George Mason press guide as a guard.

"Rob has been doing a good job for us all fall," said Coach Joe Harrington. "He sneaks up on you. He has the arms of a 6-7 or 6-8 player and he can play any position on the court."

Rose did enough as a forward to leave the New Jersey team gasping. Besides making 11 of 17 shots from the floor, he had a game-high 14 rebounds, had three assists, blocked two shots and was credited with two steals.

"Coach told me earlier today that I was starting and I really got my mind into the game," Rose said. "This was my first home game and I wanted to make it a good one."

The Patriots (2-1) built a 14-point halftime lead with a strong inside game that Monmouth could not control. George Mason shot 63 percent from the floor in the first half, with Yates making seven of eight, Rose six of eight.

Monmouth was hurt when its 6-10 center, Jesse Stout, was charged with his third personal foul after only 6 minutes 49 seconds. Stout sat out most of the remainder of the half and finished with only seven points and three rebounds.

This was the first of four visits to this area for Monmouth, a Division II playoff team that will return later to play George Washington, Georgetown and Howard. It will also meet District of Columbia in a tournament in Erie, Pa., as it faces an impossible schedule, with 16 of its first 19 games away from home.
