Could two be the loneliest number in volleyball?

Orestimba and Merced didn't appear to have much of a shot in the Sac-Joaquin Section volleyball playoffs, not as No. 15 seeds making long road trips in Tuesday's opening-round matches.

They'll be back on the court tonight, however, after pulling off stunning upsets of No. 2 seeds.

Orestimba's five-game win got it a trip to Hilmar (27-3), to face its Western Athletic Conference rival in a Division IV quarterfinal. Hilmar is 2-1 against Orestimba (22-9), though the Warriors won the last match.

Merced (18-10) will face another surprising foe when it plays Folsom (21-7) at Vista del Lago High in Folsom in Division I. The No. 10 Bulldogs upset Modesto Metro Conference champ Modesto.

Except for those three upsets, opening night went close to form with 18 of the top 20 seeds in the five divisions coming out on top.

Ten other Stanislaus District teams also play in tonight's quarterfinals, but only three host:

Ripon (31-7) , a section finalist last year and the Division IV top seed, hosts Le Grand (23-5).

Division III No. 3 Sonora (27-10) hosts Union Mine (16-10).

Division V No. 2 Stone Ridge Christian (23-16) hosts Ripon Christian (23-8) in one of two all-district quarterfinal matches.

While the rest of the district's teams must travel to face higher seeds, that doesn't mean their chance to earn a victory is slim.

Buhach Colony (21-9), after rallying late in the regular season to capture the Central California Conference title, is at No. 4 Yuba City (32-5) in Division II action.

BC is one of three CCC teams playing: Runner-up Golden Valley (13-5) visits Division I top seed and three-time defending champ Nevada Union (39-4).

Oakdale (25-8), second to Sonora in the Valley Oak League, is at No. 4 Del Oro of Loomis (17-12) in Division III. The Golden Eagles' record is deceiving, though, because they trailed Nevada Union and Division II top seed Rocklin in the Sierra Foothill League.
