The Lathrop High girls basketball team doesn’t have a playoff run to look forward to, but it isn’t going out without a fight.The Spartans shook up the top half of the Valley Oak League standings with their surprising 46-45 win over visiting Sonora on Tuesday, dropping the Wildcats into a third-place tie with East Union in the hunt for the final Sac-Joaquin Section playoff berth.Lathrop (3-8 VOL, 7-16 overall) came through in crunch time for its biggest victory of the season. The Spartans erased a 38-27 deficit with a 19-point onslaught in the fourth despite their best player, Loreal Taylor (six points, 13 rebounds) going down with an apparent knee injury. “That just fired our girls up defensively and they started to pick up the offense,” Lathrop coach Ed Fang said of Taylor’s possible season-ending injury.Point guard Lauren Collins drilled three of her seven 3-pointers and led Lathrop with 19 points, five rebounds and four assists.
