CHICO -- The Cal State Stanislaus baseball team needs to beat Sonoma State today at 3 p.m. or its season is over.
The Warriors lost to Chico State 4-2 on Thursday in the first round of the NCAA Division II West Region Championship at Nettleton Stadium.
Kevin Seaver's single up the middle in the third inning scored two runs to key a three-run rally that gave Chico (40-15) a 4-0 lead.
The Wildcats earned their fifth consecutive 40-win season; they play UC San Diego today.
Never miss a local story.
In earlier games Thursday, Sonoma State pounded Nebraska-Kearney 15-2, and UC San Diego beat Western Oregon 5-3.
Warriors ace Marquis Fleming, the West Region Pitcher of the Year, settled down after early trouble. Fleming didn't allow a hit after the third inning.
In what perhaps could be his final collegiate start, Fleming threw 145 pitches, allowing six hits while striking out six and walking six.
"The beginning was rough. I was overly amped up for the game," Fleming said. "After three innings, I was able to settle down and we scored some runs, then I was just running on adrenaline."
Chico starter Pete Mickartz allowed five hits and struck out 13.
Stanislaus scored twice in the sixth. Jeff Hughes led off with a homer and Jacob Thelen drove in Jeff Bellotti with a two-out single.
The Warriors (37-22) weren't able to cash in on other scoring chances. Adam Fonville led off the third with a single and advanced on a passed ball, but Mickartz got Tom Long and Hughes to strike out swinging. After Chico intentionally walked Kyle Loretelli, Bellotti flied out to left.
Chico scored once in the second on two hits and an error.
