The Trans-Valley and Southern League boys singles champions were one and done in the Sac-Joaquin Section Coed Tennis Tournament at Oak Park in Stockton on Thursday. Manteca High’s Division II Tournament qualifiers also had a short day at Johnson Ranch Racquet Club in Roseville but has its Division III semifinal team match to look forward to on Monday. The only area players to win a match were Ripon’s girls doubles tandem of Alli Hickman and Sami Hyer, who swept a pair from Highlands in the opening round.
