FOUNTAIN VALLEY — Newport Beach resident Joseph DiGiulio, who is ranked No. 1 in the nation in the boys' 12 division, defeated Thien Nguyen 6-3, 6-1 Saturday in the quarterfinals of the 105th annual Southern California Junior Sectional Championships.
DiGiulio, who is unseeded because he hasn't played in Southern California as much, will face fourth-seeded Gage Brymer of Irvine in a semifinal today at 1:30 p.m. at the Los Caballeros Racquet and Sports Club in Fountain Valley.
The championship is Monday at 11 a.m. at Los Cab.
