No. 1 St. John’s finishes as the Washington area’s top-ranked girls’ team, a season-ending perch that No. 6 Riverdale Baptist had held for the past four years.

Paced by senior guard Lindsay Allen, the Washington Catholic Athletic Conference player of the year and the area’s only McDonald’s All-American, the Cadets finished 33-1 and won the WCAC and Bishop Walsh Girls Invitational Tournament titles.

The dynamic Allen averaged 16 points, 8.0 assists, 6.5 rebounds and 2.5 steals and shot 82 percent from the foul line, and the team got a steady contribution from senior forward Tori Oliver, another first-team all-conference choice and the most valuable player at the BWGIT.

The emergence of sophomore guard Amari Carter and the play of senior center Jasmine Bailey, the WCAC defensive player of the year, helped four-year varsity members Allen, Oliver and Bailey depart with a 118-18 career record.

“It’s an unbelievable run for these seniors,” St. John’s Coach Jonathan Scribner said. “Two championships, three Bishop Walshes, four [WCAC] championship appearances. Those are pretty explosive numbers.”

St. John’s took two of three games from defending league winner Good Counsel, including in the WCAC championship. The Cadets topped No. 3 Spalding (29-2) in the BWGIT championship, their third straight crown at the Cumberland, Md., event. Good Counsel (27-6) finishes as the fourth-ranked team in the area.

Spalding’s season will spill into April, when the Cavaliers play in the National High School Invitational at Georgetown Prep on ESPN. Spalding beat both Riverdale Baptist (29-6) and Good Counsel this season.

North Point, which capped a 27-0 season with a Maryland 4A title finishes as the second-ranked team, and the only public school squad in the top six. Paul VI Catholic (29-4), which started 23-0, rounds out the top five.

Knights finish strong

For the first time in school history, O’Connell finishes as the Washington area’s No. 1 boys’ team after winning the WCAC and Alhambra Catholic Invitational tournament crowns.

The Knights posted a 30-7 record and punctuated their campaign with a win against Benedictine in the Alhambra final, avenging a loss to the Cadets in the Virginia Independent Schools Athletic Association Division I championship.

Junior guard Melo Trimble, a Maryland commit, led the way for O’Connell with an average of 20.8 points per game, including totals of 33 and 34 points in the WCAC and Alhambra finals, respectively, to earn MVP honors at both events.

“All the credit goes to these players with the determination they showed and being an in­cred­ibly coachable group,” said Knights Coach Joe Wootten, whose team went 14-18 last year. “We had a very strong regular season within the WCAC and we just kept getting better and better. They came to practice hungry every day, wanting to be coached and wanting to be successful.”

Two of O’Connell’s losses came against No. 3 Gonzaga (27-5), which became just the third school to go undefeated in WCAC regular season play. The Eagles finished third at Alhambra after beating nationally ranked La Lumiere, a team that will be joined by No. 2 Montrose Christian in April’s National High School Invitational.

Montrose Christian (19-4) ended the regular season on a 10-game win streak, including a triple-overtime win against nationally ranked rival Oak Hill Academy. The Mustangs, who went 2-4 against locally and nationally ranked schools, will face the country’s top squad, Findlay Prep, in the first round of the NHSI on April 4.

Eleanor Roosevelt, winners of 15 straight, finished fourth after winning its first Maryland 4A state title since 2002. Along the way, the Raiders defeated No. 18 Wise, No. 5 North Point and No. 8 Magruder.
