Jacob Peterson and Sierra fended off a last-inning threat from visiting Central Catholic on Tuesday, inducing a game-ending 4-6-3 double play turned by middle infielders J.T. Ortiz-Martinez and Diego Duarte in a 4-3 victory that starts off the Valley Oak League schedule for the Timberwolves.
Sierra (1-0 VOL, 6-4 overall) did all of its damage in the bottom of the third. The Raiders (1-2, 3-6) struck first in the top half with Orlando Leon’s RBI double.
Peterson answered with a two-run double of his own, and he was followed by RBI knocks from Hunter Frisk and Jaden Pina as the T’wolves staked a 4-1 lead. Central Catholic added two more in the fourth. Chase Costa (2 for 4) drove in a run with an infield hit, and Leon (2 for 2) drew a bases-loaded walk.
Jesse Babauta (2 for 3, double) and Ortiz-Martinez each rapped a pair of hits for Sierra, which totaled 10. Peterson scattered six hits in the complete-game win.
The series shifts to Central Catholic on Thursday.

Kimball 8, Lathrop 3

Lopez had the hot bat for the Spartans throughout, finishing 3 for 3 with a leadoff triple in the sixth. Kimball reliever Ryan Rivera took the mound after that, striking out two of the next three batters to preserve a 4-3 lead.
