The top five from the field of 17 will move on to the CIF Individual Tournament, which will be held May 16 at a site to be determined. The cut to move on to today's round, based on total strokes adjusted and the scores from the first five league matches, was 328.
Cho turned in the best effort among the local athletes, shooting a four-over-par 76. Chia and Park shots 81s, while Park finished with an 85 and Peskett carded a 91.
"I think Adrian was frustrated because he had a double-bogey to start with on the first hole," Crescenta Valley Coach John Pehar said. "That might have messed him up a little bit.
"He had a birdie on the ninth hole after getting a double-bogey on the sixth."
Pehar said the quartet of Falcons who will compete today are familiar with Brookside No. 2, something that might help them climb up in the field.
"It's a smaller course and it plays easier," said Pehar, whose team finished third in league and will next participate in the CIF Northern Team Divisional at Soule Park in Ojai on Monday. "I think the scores will be better.
"If they hit it on the greens, then they will be OK. It's going to be a difficult task for a top-five finish, but they can all certainly shoot in the low 70s. They will have to shoot under-par rounds and also hope for several of those ahead of them will self destruct."
David Moreno had an 84 for Crescenta Valley, which got a 95 from Patrick Kallas.
Evin Davis of Pasadena and Burroughs' Kelsey Danzeisen each had 72s on Tuesday to lead the pack, while Richard Jeong of Arcadia was third with a 74.
Kevin Aguirre of Glendale finished with a 94.
