The postseason has arrived. For some teams, at least.

Maryland public schools finished the regular season this past weekend, and playoff action will begin Friday. All six ranked Maryland teams took care of business last week, and each earned a No. 1 or No. 2 seed in its respective region.

In the Washington Catholic Athletic Conference, St. John’s continued to bounce back from a rough nonconference schedule by beating yet another league foe. The Cadets came up with two big defensive stops in the fourth quarter to hold on for a 24-20 win over DeMatha.

In the Interstate Athletic Conference, everything comes down to next week’s game between Georgetown Prep and Bullis. The Bulldogs pulled off a surprising rout of Landon this weekend and will face the Hoyas in their regular season finale. With both teams at 3-0 in conference play, that game will produce a champion.

And in Virginia, there are two big games looming in the final week of the regular season: Lake Braddock against South County, and Stone Bridge against Broad Run.
