Cal will travel to Corvallis, Ore., to take on Oregon State (41-13) in the Super Regionals Friday and Saturday.
Seniors Lindsay James and Haley Woods led off the fourth inning with back-to-back singles to left field. Vickers nailed a double down the right field line with one out, sending James home for the 1-0 lead. Woods scored on a wild pitch. Cal bumped its lead to 3-0 when sophomore Chloe Kloezeman grounded out to second, allowing Vickers to touch home.
The Bears scored their final three runs in the seventh. Senior Emily Friedman hit hard a single that the pitcher knocked down, allowing sophomore Erika Racklin to score on the play. Two more touched home when Vickers hit a hard bouncing single to the shortstop, sending Sutton and sophomore Jessica Moore home. Sutton led off with a single, and Moore was pinch-running for Woods, who was intentionally walked.
Freshman Gina Leomiti finished 2-for-3 Sunday, including a stand-up double to lead off the third inning.
Nebraska scored its only run on a home run from Trisha Tannahill in the seventh. That run snapped Thorson's streak of consecutive innings without an earned run at 40, dating back to the May 11 game against UCLA.
Cal also defeated Nebraska Saturday. Thorson one-hit Nebraska and struck out 12, and Woods hit two home runs in Cal's 4-2 win.
Cal is now 4-0 against the Huskers in postseason play and 12-14 overall. This was the second time in three years the Bears faced Nebraska in a regional championship game. In 2004, Cal defeated the Huskers 2-0 for a trip to the Super Regionals. The Bears went 4-0 in the Nebraska Regional that year.
