Carl Liebert scored a career-high 20 points and led Navy to a 105-55 victory over Case Western Reserve tonight before 1,075 at Halsey Field House.

Sent into the game when Coach Paul Evans benched his sluggish starters at 16:05 of the first half, Liebert, a lanky 6-foot-6 junior, scored 10 of the Midshipmen's next 16 points as Navy (2-1) registered its highest point total in 35 years.

"I didn't expect to get in that early," said Liebert, whose 22 minutes of playing time were more than double his previous season total. "But the coach said he'd do something drastic if the starters weren't producing. He was pretty upset."

Since Case Western, a Division III school from Cleveland, started no one taller than 6-4, Navy's front-line duo of 6-11 David Robinson and 6-7 Vernon Butler was expected to dominate. Instead, the Spartans hit four of their first six shots from the field and trailed by 11-8 when Evans benched his starters.

Liebert (who finished with 11 rebounds) and freshmen Nate Bailey (12 points), Bobby Jones and Neal Fenton (six assists each) filled the gap, leading Navy to a 51-30 halftime lead.

Robinson returned to start the second half and responded with 16 points to finish with a game-high 21. He also had 10 rebounds.
