Blackhawk has been tremendous defensively this season, particularly as of late.

Its latest sparkling effort came Thursday night, and it helped the Cougars finish unbeaten in section play for the second season in a row.

In a battle of the past two WPIAL Class 4A champions, Kassie Potts scored a game-high 13 points and Blackhawk’s stingy defense stepped up again in a 31-21 win at Beaver in Class 4A Section 2.

Beaver (13-7, 6-4), which had scored 94 points in a game three nights earlier, finished 7 of 43 (16%) from the field against Blackhawk (19-2, 10-0), which claimed its fifth win in a row. In that stretch, the Cougars have given up only 21 points per game. On the season, they have surrendered 31.6 a game.

“I thought we did a good job defensively on them,” said Blackhawk coach Steve Lodovico, whose team picked up its 25th consecutive section win. “We weren’t able to get on our press like we usually do because we usually don’t score like that, but I felt like down the stretch we did a great job defensively.”

Beaver was held scoreless in the second quarter and scored only 3 points in the fourth. Chloe List led the Bobcats with 7 points.

Blackhawk, the defending WPIAL champion, needed to play well defensively due to what was a surprisingly poor offensive performance. The Cougars also shot 16% from the field, finishing 9 of 55. Standouts Quinn Borroni and Alena Fusetti combined to shoot 1 of 28. Borroni finished with 5 points and Fusetti 3.
