As Catholic University Coach Jack Kvancz left Halsey Field Houe tonight following the Cardinals' game against Navy, he said, only half-jokingly, to a newman, "bring your sneakers to our next game Saturday night."

Kvancz' outmanned Cardinal team was overwhelmingly outperformed in every department tonight as Navy romped, 79-51. It was Catholic's fifth straight defeat.

Senior forward Kevin Sinnett scored 12 points to become the academy's all-time scorer. The 6-foot-6 Annapolis native and St. John's College High School (Washington) alumnus has now totaled 1,564 points. breaking John Clune's 25-year-old mark of 1,561.

"I didn't feel too nervous before the game," Sinnett said. "But once it started, something got into me. It took a while to get going."

Sinnett, who averages 20.5 points and shoots better than 53 percent, made only three of 10 shots. He reached his record total the hard way.

With the Cardinal zone blanketing him on the inside, Sinnett scored his only points of the first half on a pair of follow shots in the final 2:38. When he did get the ball while open, Sinnett more often than not passed off -- he registered three assists in the half and shared game honors in that department with five.

Sinnett canned four free throws in the second half to pull within one point of tying Clune's mark. His record-breaker came on an uncharacteristic move for the soft-spoken, unspectacular forward.

With 10:40 left in the game, Sinnett got the ball on the right side, lowered his head and drove for a two-handed slam dunk over a pair of Cardinals. The game was stopped briefly while Sinnett was presented the game ball to a standing ovation from the crowd of 1,500.

"That was only my second dunk of the year and fifth at Navy," said Sinnet. "I put a little extra into it."

Sinnett, fouled on the play, then missed the ensuing free throw -- to the surprise of nobody. But by then Navy led, 56-28.

Catholic, now 3-15, started off in a fou-corner offense. But the Mid's man-to-man defense was unyielding, forcing the Cardinals into numerous turnovers.

The visitors, who were successful on only seven of 23 shots in the first half, went scoreless for periods of three and four minutes.

Navy forward Jack Stumborg benefited from the hosts' passing game for 10 first-half points and guard Bruce Grooms added eight for a 32-17 Midlead.

Guard Chuck Greene also added to Catholic's woes, scoring a game-high 16 points -- many on bombs from the Severn River.

Bill Dankos, the second-leading scorer for the Cardinals (10.7), was limited to one of 10 from the floor by the close guarding of Sinnett and finished with only three points. a 51-45 lead and quickly picked up two long jumpers by Richardson and a tipin by Louis Wilson for an 11-point lead.

Steve Hay had 20 points and 12 rebounds for Maryland-Eastern Shore, 2-13 overall and 1-6 in the MEAC. Howard improved to 11-7 and 3-2 in the MEAC.
