Woodbridge, Brea Head Regional Field

The ultimate goal on the first day of basketball season is to win the State championship, and two Orange County teams, Woodbridge and Brea-Olinda, are favored to advance that far in this week’s Southern California Regional tournament.

The two unbeatens are the top-seeded teams in their divisions. The championship games are Saturday at Anaheim Arena.

Woodbridge (29-0), which beat Hemet on Saturday in the II-AA championship, opens the regional tournament at 7:30 p.m. Tuesday at home against Central Section runner-up Bakersfield East. The winner faces the Bakersfield North-San Bernardino winner in Thursday’s semifinals. The Warriors will be the home team as long as they’re in the single-elimination tournament.

The higher seeded team will have the home-court advantage throughout the tournament; the travel priority is Woodbridge, Division II-A champion Mission Hills Alemany (28-0), San Diego Mission Bay (28-0), Bakersfield North (24-3), Hemet (21-6), San Bernardino (25-6), Escondido (26-4) and Bakersfield East (17-8).

Division III-AA champion Brea (29-0), which has won three consecutive State championships, plays host to San Diego Scripps Ranch (20-5) on Tuesday and will then play the Lemoore-San Luis Obispo winner.

Newport Harbor (22-7), which lost to Brea, opens at section III-A champion Lompoc. The travel order is Brea, Santee Santana (25-3), Lompoc (22-7), Lemoore (20-6), San Luis Obispo (18-10), Newport Harbor, Dinuba (22-2) and Scripps Ranch.

Division I-A runner-up Mater Dei (24-4), seventh on the travel priority list, plays at No. 2 Fresno Clovis West (25-1), the Central Section champion. Should the Monarchs win, they’ll play the Los Angeles Crenshaw-Rolling Hills Peninsula winner.

The travel order is section I-AA champion Lynwood (29-1), Clovis West, Vista (20-7), Los Angeles Crenshaw (22-5), section I-A champion Ventura Buena (24-2), Peninsula (22-7), Mater Dei and Bakersfield (22-4).
