ANNAPOLIS, NOV. 30 -- Navy lost its team leader eight seconds into overtime tonight and proceeded to be upset on its brand-new parquet floor, 89-81, by NCAA Division II Slippery Rock.

Rich Brennan, and tough man-to-man defense in the final minute, saved the Midshipmen (1-1) from regulation-time defeat. Brennan made a jump shot from the foul line to tie the game at 75, and Slippery Rock (2-1) could get only a last-second shot by Myron Brown (26 points) that just missed.

Guard Cliff Rees left with 10 points, Navy's second starter to foul out. Forward Darren Morningstar, thrust into a key role at the low post due to Byron Hopkins' knee injury, went out with five minutes to play in regulation.

Freshman Joe Gottschalk, who had 13 of his 20 points in the first half but played sparingly in the second, replaced Rees and did his best to save the game. It wasn't enough.

Slippery Rock moved ahead by two points on Carroll Russell's jump shot from the foul line with 2:42 left in overtime. Navy turned over the ball and the Rockets' Richard Newell dished to Curt Williams (23 points), open under the basket, to make the score 80-76.

After Jeff Loughry hit one-and-one free throws that gave Slippery Rock a six-point lead with :54 to play, Gottschalk made a jumper from the left base line while being pushed out of bounds. His free throw made the score 82-79.

From there, Navy's full-court pressure kept putting the Rockets at the foul line, and they made five of six in the last 45 seconds.

Navy's Derric Turner, who had 23 points and 15 rebounds against Mount St. Mary's on Saturday, had 13 and eight tonight.

"We were erratic and we didn't play well defensively," said Navy Coach Pete Herrmann. "The veterans have got to play better. Derric has got to be more dominant inside and Cliff has got to stay in the game."
