Derek Hagino plays tennis for the Hempfield Knights. As a sophomore he went undefeated last season winning not only the L-L League Class AAA singles and doubles titles (with his partner Tommy Athley) but the District 3 singles Class AAA title. The videos here will give you a pretty good idea as to what he does to keep his game as sharp as possible. Regardless of the temperature on these cold March days. During the summer he competes, as most serious tennis players do, in U.S.Tennis Association (USTA) regional tournament play.
