HAYWARD, Calif. — Cal State East Bay wrapped up its postseason run on Saturday afternoon in the NCAA Division II West Regional at Pioneer Softball Field, falling 6-2 to Western Washington in an elimination game for the Pioneers. A quick start with a first-inning home run from Alexa Zumstein gave the Pioneers early life, but a four-run fourth inning by the Vikings proved to be the difference. The loss marked the end of a successful 2025 campaign for the Pioneers, who finished 40-15 overall under 10th year head coach Claire Sua-Amundson.

The Pioneers struck quickly in the top of the first inning. After Jeslyn Cuellar ripped a two-out double down the left field line, Zumstein drove a 3-2 pitch over the left field fence for a two-run home run—her team-leading sixth of the season—giving Cal State East Bay a 2-0 lead.

Western Washington answered in the bottom of the third. A pair of hit batters and a single loaded the bases with two outs. An error in right field on a ball hit by Paris Dellamaggiore allowed two runs to score, evening the game at 2-2.

The decisive blow came in the fourth inning. After a walk, a hit-by-pitch, and a single loaded the bases again, Western Washington's Emma Andrewjeski-Ramirez crushed a grand slam to center field, pushing the Vikings ahead 6-2.

Despite several base runners over the next three innings, the Pioneers could not mount a comeback. Cal State East Bay's last opportunity came in the seventh inning, but a game-ending double play sealed the result.

• Jeslyn Cuellar went 2-for-3 with a double and a run scored and finished the NCAA West Regional 7-for-11 with a double, triple, home run, two RBIs, and three runs scored.
