A scoreboard error delayed Friday night’s game between Elizabeth Seton and St. John’s for a brief moment in the fourth quarter, after game officials had accidentally turned a blowout into a one-point game. There was little protest from the crowd because that was the type of contest they expected when they arrived two hours earlier to see the second-ranked Roadrunners host the fifth-ranked Cadets.

Reality was restored a few seconds later, and St. John’s continued to hammer away at its opponent in a Washington Catholic Athletic Conference showdown. The show really ended up belonging to guard Amari Carter, though, as the junior scored 18 points to lead St. John’s to an impressive 68-47 win over Elizabeth Seton in Bladensburg.

“I’ve tried to attack more this year,” Carter said. “It was a tough week. We got game canceled. It’s been the story of our season so far. We had to come off practice hard yesterday and come and get this win.”

Senior guard Britani Stowe added 16 points for the Cadets (10-4, 6-1 WCAC), who have won four straight and have just one area loss this season.

Carter was taken out of the game in the middle of the fourth quarter during a timeout, but she put up an ovation-worthy performance with a mix of fadeaway pull-up jumpers and speed on fast breaks. She scored the final five points of the first quarter to give her team a 16-10 advantage, then opened the second quarter with five more points after earning a trip to the foul line on three straight possessions. It fueled a 26-point second quarter for the Cadets, who led by as many as 23 points in the second half.

“I knew coming to Seton was going to be a big game, big crowd, good team,” Stowe said.

It was only eight days earlier that Seton (14-4, 8-2) shook up the WCAC with a stunning one-point road win over then-No. 2 Paul VI, and the Roadrunners entered Friday’s game on a seven-game winning streak and with a week worth of rest to play the perennial league power.

All of that quickly became irrelevant against Carter. The smooth southpaw contributed in a number of ways Friday. She matched up with one of the league’s best players in Seton’s Camden Musgrave (13 points) on defense. She was aggressive on the glass. She made a number of slick passes that got her teammates easy buckets, serving as the point guard.

It’s all part of the job description for the 5-foot-7 Carter, who is following in the footsteps of former St. John’s All-Met Player of the Year and current Notre Dame guard Lindsay Allen.

“Last year we lost a lot of seniors — lost three starters,” Carter said. “I had to step up a lot this year, become more of a leader, talk to my teammates. I’m getting better at that.”
