MORGANTOWN, W.V. - West Virginia University wrestler Seth Lisa has been named the Eastern Wrestling League (EWL) wrestler of the week for his efforts at the Navy Classic this weekend.     Lisa, a redshirt freshman from Northampton, Pa., defeated two nationally-ranked wrestlers on his way to winning the 125 weight class. He defeated Jared Opfer of Kent State 6-4 in the semifinals and then earned a 4-1 decision over former ACC champion George Cintron in the finals. Lisa, who is 9-0 on the year, also won his bracket at the WVU Open last week.     The Mountaineers won the tournament with 130.50 points and Brandon Lauer, Shane Cunanan, Billy Smith, Greg Jones and Ryan Wilman all earned individual championships.     West Virginia returns to action on Dec. 6-7, at the Las Vegas Invitational in Las Vegas, Nev.
