Finally gets rolling: Bjorn Borg, 19-year-old Swedish tennis player and heart-throb, was unable to put his act together in early stages of yesterday's tennis final at CNE Coliseum. As a result, Vitas Gerulaitis took a 6-2 lead. But Borg was smashing success for rest of match as he took the $17,000 price and title, 2-6, 6-3, 6-1.
