Ali Martinez played doubles with Central Valley High School's varsity girls tennis team her sophomore and junior years.
She won 10 of 13 matches while competing at singles this season.
"I thought she'd do well," head coach Mike Rodriguez said. "But I didn't think she'd go 10-3. That's pretty impressive considering she's never played singles before. She played really well all year. She found a style that fit her. She got to every ball and lobbed it back."
Martinez posted a 10-2 record during the Western Athletic Conference regular season.
She lost 6-0, 6-0 to top-seeded Marifer Ochoa of Ceres High in the round of 16 at the WAC Singles Championships on Oct. 29 at Del Rio Country Club in Modesto.
Ochoa, a four-time finalist, won her second title.
"I was a little disappointed in the draw," Rodriguez said. "I would have liked to see her get a more favorable matchup. It's bad luck, I guess. Ali played hard and didn't quit. The other girl was a better tennis player."
Central Valley junior Emely Amaya compiled a 1-1 record en route to a top-eight finish at the WAC singles tourney.
"If she puts the time in over the summer, she'll have a pretty solid season next year," Rodriguez said.
Amaya defeated Pacheco's Jacqueline Carranza 6-1, 7-5 in the round of 16.
"That's a match she should have won," Rodriguez said. "She beat her twice this year."
Emely lost 6-0, 6-3 to third-seeded Nicole Marchese of Los Banos in the quarterfinals.
Amaya won five of 14 matches in 2013.
Amaya and Martinez lost 3-6, 6-3, 6-1 to Central Catholic's Gabby Sani and Nicole Nicholson in the round of 16 at the WAC Doubles Championships at Del Rio on Oct. 31.
"Momentum changed midway through the second set," Rodriguez said. "Central Catholic made some adjustments. We made too many unforced errors."
First-year Hawk tennis players Princess Pe and Chelsea Flores lost 6-0, 6-1 to Patterson's Kelby and Kendal Norfleet.
Pe and Flores compiled a 9-2 record while teaming up together this year.
"They really surprised me," Rodriguez said.
