In two years at Stanford, Alex Massialas has won more than 100 matches. He won 54-of-60 this season, including winning every match at the NCAA West Regional and winning 20-of-24 at the national championships.
"You get kids on the team sometimes that are in the middle of the pack. Somebody like Alex, he comes in already baked. He really already is a champion before he gets there," Stanford coach Lisa Milgram said. "His squad is better because of him."
