On the top-ranked St. John’s girls’ basketball team’s recent trip to Puerto Rico, players paired up in kayaks for a competition of sorts, with two-time All-Met Lindsay Allen and fellow senior Tori Oliver guiding one boat through a pitch-black passage.

“It was really dark out there,” Allen said. “But if you listen and pay attention, you’ll be all right.”

Having Allen and Oliver, two of the team’s primary leaders, in the same vessel provided a decided advantage for that particular kayak, just like having them on the court at the same time does for St. John’s.

Allen and Oliver combined for 44 points Wednesday night in a 77-47 win over No. 8 Elizabeth Seton at DeMatha to run the Cadets’ record to 12-0 and humble a team that was on a roll of its own and looking to make a move in the Washington Catholic Athletic Conference.

Allen finished with 28 points and Oliver had 16 points and 12 rebounds, her eighth double-figure scoring game in the past nine.

Elizabeth Seton led 6-0 and trailed by only five points entering the second half. It was outscored 21-9 in the third period.

“It’s a luxury to have really good players,” said St. John’s Coach Jonathan Scribner, whose team played the second quarter with three reserves on the floor. “We’ve got 10 deep that are contributing in one game or another. That means a lot for the longevity of a four-quarter game.”

Oliver, senior center Jasmine Bailey and freshman forward Kayla Robbins were held without field goals in the first half but each hit four shots in the second to help spur their team’s sixth consecutive win in the series.

“We have little things to work on, like running our lanes constantly, boxing out all the time,” Oliver said. “But everybody’s playing their role.”

Junior forward Casey Davis led Elizabeth Seton (9-3) with a season-high 16 points and junior guard Camden Musgrave added 15, also a season high.

Davis also grabbed 12 rebounds. St. John’s limited Roadrunners senior guard Janelle Hubbard to eight points — half her average — on 3 of 13 shooting from the floor.

“I think we kind of got away from the things that helped us be successful early [in the game] and totally working together,” said Elizabeth Seton Coach Jonathan Scruggs, whose team was coming off a holiday tournament championship in Atlanta. “I think we saw a really good team take advantage of another good team that lost their way.”

The Roadrunners’ next two games are against No. 5 Good Counsel and No. 4 Spalding.
