Jim Wilkerson, the Maryland lacrosse team's leading scorer, expanded his role yesterday, contributing four assists to lead the sixth-ranked Terrapins over No. 4 Navy, 12-10, at Byrd Stadium.

Wilkerson, who had 27 goals and six assists going into the game, also scored three times as the Terrapins (6-2) won for the first time in three weeks.

"Coach (Dino) Mattessich told me to play a little bit different role today," said Wilkerson, a junior, who scored five goals in Maryland's loss to Virginia last week. "We worked hard at moving the ball all week because Navy slides so hard on defense. Especially at the beginning of the game, I was concentrating on the pass.

"But I still felt comfortable on offense. I'll do whatever it takes to win."

"We told Jimmy we wanted him to quarterback," Mattessich said. "We knew we were going to need two or three passes before we got a shot against them. When we tried to pound the ball into the goal right away we just got stopped."

Maryland extended a 7-6 halftime lead to 11-8 midway through the final period before Navy (6-2) pulled within 11-10 on goals by Rich Wehman and Bill Anderson. Maryland's Tim Worstell scored with 41 seconds left to clinch the game.

Wehman led all scorers with five goals. Maryland midfielder Don Sadler, whose 14 assists led the Terrapins going into the game, had three goals and one assist.

Neither Maryland nor Navy generated much offense until midway through the second period. Maryland scored three times in a minute and a half to take a 5-3 lead with 11:23 gone in the period.

Steve Mutscheller scored the first goal of the spree on a pass from Tony Olmert. He was followed 26 seconds later by Sadler. Worstell then added the first of two second-quarter goals to put Maryland up by two.

But Navy, which also scored in spurts, scored on the ensuing face-off, and nine seconds later on another faceoff.

Navy and Maryland traded goals before Mike Blair scooped up a face-off and dribbled a shot in from 15 yards out with 36 seconds left in the half to put Maryland ahead, 7-6.
