Typically outsized at every position, Manteca has had to rely on speed to rack up wins this season. That wasn’t the case in its Sac-Joaquin Section Division III opener Tuesday at Winter Gym, where the fourth-seeded Buffaloes hosted standout senior Amaya Ervin and No. 13 El Capitan. In this matchup between guard-heavy squads, it was the play of junior center Paige Peterson that was the difference in what ended up as a 66-39 rout favoring Manteca.
