Georgetown Prep outscored Springbrook, 9-0, in the final four minutes of the third quarter, enabling the Little Hoyas to put away a 72-62 nonleague win yesterday at Georgetown Prep.

Junior center Mike Mulquin was superb for the winners with 21 points, 18 rebounds, two blocked shots and three steals, outplaying his Springbrook counterpart, Scott Wolz.

"It was an upset, no question about it," Prep coach Fran Gleason said. "We have the one super player (Mulquin) and the other four scrap, hustle and fight."

Prep, now 2-0, trailed at half-time, 34-31. But the Hoyas' two-three zone defense stymied Springbrook (2-1) in the third period, limiting the Blue Devils to three field goals.

"We concentrated on Wolz and (Andy) Axelsson," Gleason said. "We forced Wolz outside more than he would have liked. I think Mulquin showed a little more patience on offense than Wolz."

Meanwhile, the Prep fast break revved up, led by guard Jim Corcoran, who scored 15 of his 17 points in the second half. Prep, outscoring Springbrook, 25-7, ran its lead to 56-41 by the end of the period.

The Blue Devils never pulled closer than 12 points in the final quarter, despite excellent outside shooting from Dan Connors.

In the first half, Axelsson talled 13 of his 15 points to lead the Blue Devils, Springbrook was at its best in the second quarter, when the Hoyas played man-to-man defense. Wolz lead Springbrook with 19 points.

Prep's defense forced the 6-foot-6 Wolz, one of the best big men in Montgomery County, to take bad shots. But Mulquin stayed near the basket, taking feeds by teammate Rorary Coakley for baskets.

The Hoyas, making six fewer turnovers than Springbrook, also won the battle of the boards, pulling down 12 offensive rebounds to Springbrook's six. In the first half, Mulquin managed 12 rebounds.
