Senior Kevin Richardson's layup with five seconds left in overtime gave William and Mary an ECAC South victory, 74-73, over George Mason before 6,200 tonight. Carlos Yates set scoring records for the Patriots, but they were eliminated from the chase for the conference regular-season championship.

Yates became the all-time major-college scoring leader in the state of Virginia, passing Virginia's Jeff Lamp. He also became Greater Washington's all-time leader, passing Georgetown's Eric Floyd. Yates has 2,319 career points; Lamp scored 2,317 and Floyd 2,304. But Yates' record-breaker was his final score. He played the last 4:01 of regulation and the entire overtime without adding to his night's bag of 26 points.

The Indians moved within a half-game of the visitors in the upper echelons of the conference. W&M (12-10 overall) improved to 7-4 in the league. George Mason (15-10) fell to 8-4 and lost all chance of catching league-leading Navy, which will take an 11-2 ECAC South record into its final conference game, at George Mason on Wednesday.

Mason built the biggest lead of the five-minute overtime, 73-67, when Ricky Wilson made two free throws with 1:38 to play, but there the Patriots' luck ran out.

Forced to foul, the Tribe put Mason on the line four times for one-and-one chances in the last minute and a half. And Mason the first free throw every time.

After Tony Traver scored to cut the lead to 73-70 with 1:01 left, both Wilson and Rob Rose missed one-and-ones. Keith Cieplicki, who led all scorers with a career-high 32 points, connected from the field and it was 73-72 with 18 seconds left.

W&M's Scott Trimble then fouled Rose, who missed again. The Indians cleared the rebound and Richardson drove the lane for the winning score. GMU's Wilson missed a turn-around jumper with :001 remaining.
