ANNAPOLIS, FEB. 6 -- A scrambling Navy defense shut down Richmond's two best scorers and the Midshipmen got outstanding offensive performances from Matt Nordmann and Joe Gottschalk as Navy upset the Spiders, 73-59, in a Colonial Athletic Association game tonight at Halsey Field House.

Navy's fourth straight win raised its record to 7-12, 3-5 in the conference. Richmond, which dropped into a tie with UNC-Wilmington and George Mason for the league lead, fell to 16-4, 6-2.

Richmond's Peter Woolfolk, who entered the game averaging 19.6 points per contest, was held to eight. Rodney Rice, who scored a game-high 24 points in Richmond's 78-63 victory over Navy in January, also got only eight.

"I thought the defense carried us," said Navy Coach Pete Herrmann. "But I thought the consistency, especially in the last 10 minutes, offensively, really kept us in the lead."

Nordmann ended the night with 18 points, 13 in the second half. The 6-foot-5 sophomore scored nine in the last 4:45, seven of those from the foul line.

Gottschalk carried the Midshipmen to their halftime lead with his three-point shooting and finished the game with 16 points.

Navy led, 36-29, at the half despite Richmond's 60 percent shooting in the first half.

The Midshipmen stretched their lead to 45-33 with a 9-4 run to begin the second half, but Richmond mounted its only run of the night, scoring the game's next 10 points to cut the Navy lead to 47-43.

Nordmann scored off an offensive rebound to start a 7-2 Navy run that ended with Gottschalk's fifth three-pointer, for a 52-45 lead. Richmond cut the lead to five but Navy's free throws (17 for 23 in the second half) ended Richmond's comeback hopes.

Navy was successful early, spreading the Richmond defense with perimeter passing, then looking inside for Eddie Reddick, Nordmann and Byron Hopkins.

The Midshipmen led, 16-13, as Reddick was successful in close for six points and Nordmann got a layup and an offensive-rebound basket. Meanwhile, Rees hit a long jumper for three points and converted a backdoor layup for two more.

Richmond stayed close as it began to assert itself on the backboards, but Gottschalk's three-pointers gave Navy its biggest lead of the half, 36-27, with about a minute left.
