Semi-Pro
I know he beat Becker to win the 90 Queen's but I tend to think Lendl's Wimbledon semi final win over Edberg in 87 was his best grass court win. That is because Wimbledon is a much bigger event than Queen's and also because it was best of 5. Edberg was already a double Australian Open champion on grass and only one year away from being Wimbledon champion, and Edberg was a genuine contender for the Wimbledon crown in 87, especially after Becker was knocked out.
