Lendl is a figure that bridged two different eras of tennis. He was competitive in the era of Borg/Connors/McEnroe and also in the era of Wilander/Edberg/Becker. By the time Sampras peaked and Agassi finally got it together, Lendl was through.[/quote]
Indeed his career bridged two eras.
I would have thought his greatest rivalry was with Mc.
