EAST RUTHERFORD, N.J., FEB. 16 -- Georgetown was out-Georgetowned tonight.

One of the two teams on the Meadowlands court was grabbing a slew of offensive rebounds, snatching virtually every loose ball and harassing its opponent into turnovers. But it wasn't the Hoyas.

They were victimized by Seton Hall's role reversal and lost to the Pirates, 63-50, before 18,111.

Just at the part of the season when No. 18 Georgetown traditionally finds itself surging, it is reeling. The Hoyas lost their second straight game to fall to 15-8 overall and 7-5 in the Big East, two games behind front-runner Syracuse.

Georgetown's undoing on this sloppy evening was its 23 turnovers, its astonishing 40-28 rebounding deficit and its offensive inefficiency that produced six-minute-plus lapses without a field goal at the end of each half.

Center Dikembe Mutombo was the only Hoya to score in double figures with just 12 points (on four shots, none in the second half).

His twin-towers mate, Alonzo Mourning, made one field goal and had six points.

And Georgetown ended up a miserable 14 for 38 from the field en route to its lowest point total and most lopsided defeat of the season.

Yet the Hoyas still had a chance to win, as they narrowed a 14-point second-half deficit to 50-45 with 4 1/2 minutes remaining. But Seton Hall (16-7, 7-6) -- which beat its third straight ranked opponent -- scored the next seven points to put away the game.

Guard Terry Dehere's 22 points led the Pirates, who made a mere 19 of 53 field goal attempts and committed 19 turnovers. Center Anthony Avent was held to eight points and three rebounds, but forward Jerry Walker -- starting because Gordon Winchester missed a study hall last week -- contributed 10 points, 9 rebounds and 5 steals.

"Seton Hall did a damn good job of beating us to loose balls," Georgetown Coach John Thompson said. "That's the game we play. . . . {and} that really set the tone. We weren't responding, weren't reacting the way we should have. It was one of those nights where we couldn't do anything right at certain times in the game.

"But I still think we're in pretty good shape. There is no need to panic right now. In this league, any win on the road is an upset. . . . We are not ready to lie down and die."

Only an unaccustomed salvation -- three-point shooting -- kept Georgetown from being out of contention earlier.

The Hoyas made all four of their first-half tries from beyond the arc, two by reserve guard Lamont Morgan, and only a late five-point burst provided Seton Hall some breathing room at intermission at 34-26.

Georgetown had eight field goals and 14 turnovers in the opening 20 minutes, and Mourning and Mutombo took but seven shots total.

"They had trouble getting the ball in there to Dikembe and Alonzo," said Pirates Coach P.J. Carlesimo, whose team then held the pair to three second-half field goal attempts. "I thought we played some great defense. . . . We had a lot of people do a lot of little things tonight."

As lackadaisical as Georgetown was in the first half, the Hoyas hit new lows for sluggishness in the opening moments of the second half.

Forward Arturas Karnishovas opened the period by scoring for Seton Hall, and the Hoyas' Robert Churchwell answered. The Pirates scored 10 of the next 14 points.

They beat the Hoyas to nearly every free ball during that stretch, including one possession in which they had four offensive rebounds -- "a Georgetown possession," Carlesimo called it.

Dehere started and ended the run with three-pointers, and Seton Hall led by 46-32 with 15:03 to play. Yet the Pirates were in this position before, having held a nine-point second-half lead against the Hoyas last month at Capital Centre. That time, an 18-0 Georgetown surge paved the way for an eight-point Hoyas victory.

But Georgetown didn't make a field goal after Mourning's basket at the 7:31 mark tonight, and Seton Hall cruised down the stretch.

"We let things get away from us," Mourning said. "They took it to us and we didn't respond.

"But we'll be all right. We just have to get back home and get things together."
