Central Valley High School's varsity track and field program had one representative at the Sac-Joaquin Section Masters Championships on Thursday in Elk Grove.
Sophomore Mahogany Simon finished 17th overall in the 300 hurdles.
The competition featured 24 athletes.
"I couldn't be more proud of her," Hawks coach Nate Diamantine said. "She was running against some of the fastest girls in California. She deserved to be there."
Simon finished the race in 47.46 seconds.
Vacaville's Jurnee Woodward (41.97) and Hannah Davis (43.30), and Bella Vista's Sadye Peschke (43.92) secured individual berths to the CIF State Meet.
"We actually never talked about going to state," Diamantine said. "We talked about running a certain time. She was a second slower than her PR. At this time of the season, everybody is fast."
Simon had another success-filled season with the Hawks.
Simon took second in the 300 hurdles (46.84) at the Sac-Joaquin Section Division IV-V Championships on May 19 at Stanislaus State.
Mahogany swept the 300 hurdles (49.30) and 100 hurdles (16.71), and finished second in the 200 (26.95) at the WAC Finals on May 12 in Merced.
"The most satisfying thing for me is how much her technique has improved," Diamantine said. "I'm not surprised. She's such a hard worker. She'll continue to grow."
A two-time Masters qualifier, Heaven will set her sights on doing even better next season.
Will Simon qualify for state?
"I don't see why that goal can't be achieved in the future," Diamantine said. "With Mahogany, anything is possible."
Older sister Heaven Simon ranks among Central Valley's all-time greatest athletes.
Heaven claimed four individual titles at the 2015 WAC Championships. She placed first in the 100 (13.09), 200 (27.05), 400 (59.59) and 300 hurdles (46.85).
She won the 300 hurdles (48.53) and 400 (1:04.68) at the conference finals in 2014. She also ran a leg on Central Valley's winning 4x100 and 4x400 relay teams.
She took first in the 400 (1:03.35), and second in the 200 (26.60) and 300 hurdles (51.56) her sophomore year.
Heaven finished first in the 400 (1:05.81), third in the 100 (13.35) and fifth in the 200 (28.36) as a freshman.
"Mahogany is proud of her sister's accomplishments," Diamantine said. "It's never been a motivating factor or roadblock for her. We know she has the ability to be successful in her own right and make her own mark."
