With fans not allowed in Dobbins Stadium at UC Davis on Friday, a few climbed to the roof of a parking garage to watch the Aggies’ season opener against Washington State. They probably had a better time than Brett Erwin, who did not appear to be that happy when coach Matt Vaughn pulled the Armijo High graduate with two outs in the fourth inning. The junior kept the ball in his glove as Vaughn walked to the mound instead of having it ready to hand over as if to indicate he did not want to come out. The Aggies lost 11-1, scoring their only run in the first inning when Jalen Smith (15) raced home on a passed ball.
