Janita Vongphoumy made her debut with Central Valley High School's varsity girls golf team last week.
A transfer from Rhode Island, Vongphoumy fired a 3-over-par 32 during the Hawks' 141-180 loss to crosstown-rival Ceres High on Sept. 16 at St. Stanislaus.
"They surprised us," Bulldogs' head coach Randy Cerny said. "We had no idea she was on the team. We thought it was going to be a cakewalk"
Central Valley dropped to 0-4 in the Western Athletic Conference standings.
First-place Ceres High improved to 5-0 WAC play.
"She (Janita) definitely changes the makeup of our team," Hawks head coach Kelly Wheelock said. "The two matches we lost early, we probably would have won if we had her. She's a game-changer."
Janita lost by just three strokes to Ceres High senior/two-time WAC MVP Caitlin Pfaff.
Vongphoumy's older sister Juliet is a standout golfer at the University of Maryland.
"It's a neat story," Cerny said. "She (Janita) can play. She's only a junior. She's going to give us fits next year."
Arriana Ayala (47), Else Smith (49) and Soraida Felix (52) rounded out Central Valley's scorecard.
Pfaff led all golfers with an even-par 29.
Erica Hogner, Brittany Turnbow and Abigail Nou finished with rounds of 36, 37 and 39, respectively.
Ceres High has won six of its last seven head-to-head matchups with Central Valley.
"All of the girls are excited," said Cerny, whose team is a heavy favorite to win its first-ever league title. "They know it's within grasp. They're working very hard. They're not slacking. We have to play our best regardless of who we're going up against. I got to keep them focused. We don't want to look past anybody."
