At Robinson on Saturday, a flash of purple tore down the court and abruptly stopped.

Potomac Falls sophomore forward Wanya Allen, sporting a faux-hawk dyed to match his school’s primary color, elevated and dropped in his second consecutive three-pointer in the second quarter of a 73-53 victory over Chancellor in a Virginia AA Division 4 quarterfinal in Fairfax.

Allen capped off the play with an exuberant bark and a flex of his right biceps. The 6-foot-3 forward’s dirty work inside gave him space to attempt three-pointers, so he knocked them down and put his team up by 15 points with a little more than two minutes left in the first half.

“I just felt good hitting them, so I had to show somebody something,” Allen said.

Allen led all scorers with 25 points. Potomac Falls (26-4) advanced to the state semifinals for the fourth consecutive season. In the first two of those trips, Potomac Falls returned from Richmond with a championship trophy.

The Panthers travel to VCU Tuesday for a 9 p.m. tip-off against Salem, which defeated Heritage-Lynchburg, 53-45.

Potomac Falls dominated Saturday’s contest; it led by 25 points in the fourth quarter.

But it was not an auspicious beginning.

After his team missed its first three shots and fell behind, 6-0, to open the contest, Potomac Falls Coach Jeff Hawes called a timeout that sparked a 7-0 rally. Freshman Michael Janowski capped off the run with a tip-in around the six-minute mark.

The Panthers did not cede the lead for the rest of the game.

“They came out ready to go, and we came out a little flat-footed,” Hawes said. “[Give] credit to them. They weren’t scared of us because we’re Potomac Falls. We had a little chat in that timeout.”

Senior guard Brandon Orbe came out of the timeout and hit a three-pointer, then Allen converted a layup before Janowski’s bucket.

Senior guard D’Shawn Shorts poured in nine of his 12 points in the first half and Janowksi also added 12.

Chancellor senior forward Chris Holmes, a high-flying athlete who has committed to play football at Duke, led the Chargers (17-6) with 18 points.

“He’ s a real tough matchup,” Allen said. “He’s big, he can rebound, he can jump [and] he can shoot.”

Chargers senior Ryan Greer contributed 16 points, including two three-pointers in the fourth quarter.

Potomac Falls was knocked out in last season’s semifinal round.

When asked about the Panthers’ future, Allen predicted a different finish this year.

“[We’ll be] state finals champions,” he said.

BRUNSWICK 24, LOUDOUN VALLEY 22: The Vikings (25-5) could not convert their final possession and fell to Brunswick in a Virginia AA Division 3 quarterfinal at VCU.

Trailing 18-9 at halftime, Loudoun Valley held Brunswick’s ball control offense to six points after the break.

“I couldn’t be more proud of the boys,” Loudoun Valley Coach Chad Dawson said. “They played exactly how they were supposed to.”

The Vikings, Region II Division 3 runners-up, shared the AA Dulles District regular season title with Potomac Falls.
