The College of San Mateo softball ran its playoff winning streak to 10 in a row and six during the 2026 postseason as the Bulldogs moved into the winner bracket’s final of the 3c2A state tournament play after beating Cosumnes River 7-2 Friday morning at Bakerfield College.
CSM (42-1) — the defending state champ, top-ranked team in the state and the No. 1 seed of the four Northern California teams in the state final eight — opened the 2026 postseason with a 2-0 sweep of 16h-seeded Lassen in the regional round and dispatching No. 8 Feather River in two straight games in a Nor Cal super regional last weekend. The Bulldogs opened state tournament play Thursday with a 6-2 win over Saddleback, the No. 4 Southern California seed.
The Bulldogs had beaten No. 3 Nor Cal seed Cosumnes River 7-6 earlier this season, but it was the Hawks who took a quick lead Friday, scoring once in the top of the first inning.

CSM, however, took control of the game in the bottom of the second, scoring all seven of its runs. After that, Bulldogs pitcher Lola Sierra took over. She pitched a complete game to improve to 28-1 on the season. After giving up a run in the first, she shut down the Hawks until they scored another run in the top of the fifth as Sierra held Cosumnes River to just four hits, striking out five and walking two.
While the Bulldogs did not add to their record-setting home run record, they still had six players drive in a run. The big hit was a two-run double from Hannah Ames. Nia Mapa added a sac fly, while Alyssa Green, Love Cabanas, Peyton Huber and Lilyana Williams all drove in a run, as well.
