STOCKTON — The mats can be unforgiving at the Sac-Joaquin Masters Wrestling Championships, and Friday’s action was no different with only three of 12 local qualifiers advancing to the second day of competition this morning at the Stockton Arena. Ripon’s Donny Fontillas (132 pounds) made it to the quarterfinals with a 7-5 decision over Tokay’s Trenton Edalgo and a 9-3 decision over Yuba City’s Kirino Delafuente before being tripped up by Pitman’s Samuel Silveria, 8-0. “We won some matches,” Indians coach Glen White said.
