Rare is it that Classen SAS is tested during the regular season.

Entering last Thursday, the team out of Oklahoma City had won all but one of their games in 2021-22 — they fell to Etiwanda (Calif.), 53-51, on Dec. 22 — and appeared ready to head into the postseason on a high note. That is, so long as they could get past Edmond North, which entered Thursday’s showdown with a 21-0 record.

In the end, Baylor commit Darianna Littlepage-Buggs and Classen SAS overcame a double-digit deficit to claim the 58-56 victory. The statement win helped the Comets bump up to No. 6 in this week’s rankings. Sidwell Friends remains at No. 1 after another high-profile victory.
