Vandernaald allowed one hit in 3 2/3 innings to earn his third win in as many decisions this season. The freshman right-hander has not allowed an earned run this season in 15 2/3 innings.
"He's been doing a good job," Altobelli said of Vandernaald. "He struggled a little in the fall and in January and he was kind of a question mark for us. But he has thrown some good innings and done a good job. Guys like that rising to the occasion has been nice."
Freshman Chad Thompson, a heralded prospect out of El Toro High who is in the early stages of a return from Tommy John surgery, struck out one in one scoreless inning. He has now worked the scoreless innings this season.
