Sophomore McKenna Maycock couldn’t buy a basket during warmups Thursday night.

“I just told her to relax,” Randolph coach Shawn Huntington said. “Your best games usually come when you can’t make anything in pregame.”

That was certainly the case, as Maycock went off for a triple-double with a school-record 42 points, 15 rebounds and 11 assists, leading the second-seeded Cardinals to a 74-52 victory over No. 3 Tapestry in a Section VI Class C-1 semifinal game.

Maycock broke the record of 40 points that was set in 2011 by her older sister Marah, the school’s all-time leading scorer with 2,326 career points. McKenna now has 1,580 in her sophomore year.

“She’s pretty intense,” Huntington said. “He likes to win. She got on a roll and just started hitting buckets.”

In the second semifinal, senior Abby Watson set career highs with 24 points and 21 rebounds in Allegany-Limestone’s 43-36 victory over Holland. The Gators (11-9), who also got 13 points from senior Halee George, held Holland without a point in the second quarter. Olivia Schmidt led Holland (13-4) with 16 points.

Park wins a pair

The Park boys team won its third Independent Athletic Conference championship under coach Michael Battaglia with a 67-54 victory over Gow, pulling away in the second half of a game that was close at halftime. Sean Buckley had 18 points for Park (14-7), while Grant Sepiol had a game-high 22 for Gow (12-4), which suffered three of its four losses on the season to the Pioneers.

Seychelle Mikofsky had 25 points and Jessica Myszka added 17 as the Park girls won the IAC championship with a 53-17 win over West Seneca Christian.

Elsewhere, Immaculata closed the game by outscoring Holy Child, 14-6, in the fourth quarter for a 42-35 win in the quarterfinals of the New York State Association of Independent Schools tournament at New Rochelle College.

The Bears (20-4) got 15 points from senior Taylor Heinold and 11 from her freshman sister, Jordan. Immaculata went 10 of 14 from the free-throw line, while Holy Child was just 4 of 10.

Immaculata plays at Fieldston (Bronx) at 5 p.m. today in the semifinals.
