The cut was 72 and 124 golfers competed in the event.
The top six advanced to the CIF-State Championship, which will be held at 7:30 a.m. today at Red Hill Country Club in Rancho Cucamonga.
Cho, who was named the league's most valuable player after helping the Falcons go 25-2 this season, finished with 11 pars, six bogeys and one birdie after starting on the 16th hole in the shotgun format.
Cho opened with a bogey, but parred seven of the next eight holes, the only exception being a birdie on the second hole. She ran into trouble when she registered bogeys on the 11th, 14th and 15th holes, however.
"I had a pretty good start, and I was even for most of the first nine holes," said Cho, who competed in the event for the second consecutive year. "After that, I had three more bogeys.
"I'm a little disappointed because I was hoping I could do better. It's not a terrible score, but maybe I'll remember the course more and try again next year. It's definitely my most exciting year, because we got so far as a team."
Cho, who finished 19th out of 110 participants at last year's event, helped the Falcons win the in the CIF Southern Division Team Regionals at Yucaipa Valley Golf Club on Oct. 30. Crescenta Valley placed 12th out of 16 teams at the CIF Southern Section Team Finals on Nov. 1 at the Soule Park Golf Course in Ojai.
Salvo, who is a junior at Sherman Oaks Notre Dame, helped the Knights capture their fifth consecutive Mission League championship in October. She finished with 15 pars and three bogeys in her third straight final.
"She had three opportunities, but couldn't quite make the putts go in," Notre Dame Coach Ann McClung said.
