Quotable: “Well – after four years of finding it exceptionally difficult to coach against Alex Chang as a member of the Cal men’s tennis team, we are fortunate to now be able to say to Alex, “if we can’t beat you, will you join us?” Alex is an exceptional player who hails from the Bay Area. His improvement over his four years at Cal was as, or more, pronounced than any player we can recall in the last decade. We are truly thrilled to have the opportunity to work with Alex for his final year of eligibility while he pursues a master’s degree at Stanford.” – Paul Goldstein, Taube Family Director of Men’s Tennis
