That had to hurt him. He also went 2 of 7 in the '83 Wimby semis vs Mac. Lendl's numbers in this stat seem almost as poor as Becker's.
Lendl made 1st serves on 9 of 10 break points vs Tanner at '83 Wimbledon. And he served a 2nd serve ace after the only 1st serve he missed down break point. Wasn't broken in the match.
Mac 12 of 15 vs Sanchez at '90 USO
Kuerten 6 of 7 vs Agassi at '00 Masters Cup, 8 of 10 vs Sampras at same event
