Lendl converted only 1 of 16 break chances (6.3%) in that Dallas match, a very poor performance for him. It would be interesting to find out how many first serves McEnroe made on those break points. Was it a case of McEnroe saving them, or Lendl failing to convert break chances the way he normally did? Again there's a parallel with the '81 Wimbledon final: McEnroe and Borg each converted only 2 of 15 break points. There was no real failing there on Borg's part, because McEnroe made 12 of 15 first serves on break points.
