Amazing that Lendl didn't win a major in those years with that many wins!
Indeed. He couldn't beat Jmac, Connors, Borg in the big matches.
In fact, when he went on his 18 finals in a row streak, it was between
the USO and Roland Garros. Amazing that he could play so much, but a lot of it was when he wasn't playing JMAC or Connors.
