Manteca may be finding its groove, and just in time for the second half of the Valley Oak League schedule. The Buffaloes conquered visiting Weston Ranch in a commanding 25-7, 25-23, 25-10 sweep on Wednesday, playing vastly better than they did in their previous showdown that resulted in a more competitive four-game win. “They’re one of those teams that can sneak up on you,” Manteca coach Kevin Bolding said of the Cougars (1-6 VOL, 2-8 overall).
