Lathrop and Ripon Christian highlight six Manteca-area teams in the Sac-Joaquin Section postseason brackets released on Friday.

They’re the No. 1 seeds in Divisions III and IV, respectively. Meanwhile, three-time Valley Oak League champion Manteca has been awarded a first-round home match in the more-competitive Division II.

The postseason begins next Tuesday with match times set for 7 p.m. The finals are on May 14 at Natomas High in Sacramento.

Division III features four local teams with undefeated Lathrop topping the field. The Spartans (26-0) have claimed their second Western Athletic Conference title and is ranked ninth overall in the Section, according to MaxPreps computer ratings. They only dropped three of their 77 sets in the regular season.

Lathrop welcomes No. 16 Venture Academy (8-8) of Stockton on Tuesday.

An area club could have a shot at Lathrop in the second round, as Trans-Valley League runner-up Ripon (16-9) plays host to VOL runner-up Sierra familiar foe Sierra (11-5) in the Nos. 8-9 matchup. The two teams previously faced off March 2, with Ripon prevailing 25-19, 23-25, 25-15, 14-25, 18-16. Both schools are making their first postseason appearance for boys volleyball.

Also in Division III is East Union (10-9), the third-place team out of the VOL. The Lancers were slotted at No. 13 and travel to TVL champion Livingston (17-3), the TVL champion.

Manteca (16-6) is seeded seventh in Division II and drew No. 10 Elk Grove (8-8). A victory likely sets the Buffaloes up with a trip to Grass Valley, home of No. 2 Nevada Union (26-5). NU is the fourth-ranked team in the Section.

The top two seeds gets byes in the 14-team Division IV bracket. Southern Athletic League champion Ripon Christian (23-1) awaits the winner of Ben Holt Academy (21-13) and Woodland Christian (7-7). John Adams Academy (25-3) of Roseville is the No. 2 seed.
