Gonzaga forward Finn McCaslin was still a bit wet from the water that had been tossed around in celebration as he tried to verbalize what he was feeling when the ball fell at his feet in the final minute of Sunday night’s Washington Catholic Athletic Conference championship game.

“I just can’t even describe it in words,” he said, breathless.

McCaslin’s late goal had lifted the Eagles to a 2-1 WCAC championship victory over Good Counsel. It was a shocking turn of events after Good Counsel had been leading for most of the match, but now is officially time for shocking things to happen: it’s the postseason.

Like Gonzaga, some champions have already been crowned. St. Albans shut out Georgetown Prep to repeat as Interstate Athletic Conference champions. Potomac School took down Sidwell Friends in penalty kicks in the Mid-Atlantic Athletic Conference final.

In the District of Columbia Interscholastic Athletic Association, School Without Walls won a title after entering the postseason as the No. 4 seed. Next, the Penguins will be the No. 9 seed in the DCSAA tournament, which begins Tuesday. St. Albans, Sidwell Friends and Bell will serve as the top three seeds.

In Maryland, the state semifinals are set. At the 4A level, four local teams make up the field. Whitman will face Wootton on one side, and Leonardtown will take on Arundel on the other. Whitman beat Wootton, 1-0, in a dramatic game two weeks ago. Leonardtown and Arundel have not faced each other this season.

In the 3A bracket, Mt. Hebron will face Wilde Lake for a spot in the state championship. The teams faced off on Oct. 10, with Wilde Lake winning, 1-0.

La Plata is the only local team left in the 2A bracket. The Warriors will face Parkside.

And in 1A, International High School at Langley Park has made it to the state semifinals for the third time in four years after a surprising 1-0 victory over defending champion Patterson Mill in the quarterfinals. The Phoenix will face Francis Scott Key.
