The Lady Cats scored one run in the top of the first, but the home team tied the contest in their half of the inning and never trailed again.
The Vaqueros scored three runs in the second and added four runs in both the fourth and fifth innings to plate their 12 runs. The Lady Cats pushed across another single run in the top of the third, but that was it, as the San Diego pitcher limited the visitors to just four hits.
The home team was helped a great deal by the 12 S-T errors in the game. Dolores Hinojosa blasted a double for the Lady Cats, and Tatiana Maxwell was credited with one RBI.
The varsity girls host Freer on Tuesday and will be in Bishop on Friday to play the Badgers.
