Tennis on Campus: We'd love to be on court with @reillyopelka and @bigfoe1998, who were treated to a workout with 4x Grand Slam champion Jim #Courier at our #NationalCampus in #LakeNona. Have you gotten your #Monday practice in? #USTA cc @teamusatennis _ #Tiafoe #Opelka #TennisCourt #USTennis #Tennis #TrainHard #Florida
