If Lendl dominated one of the two traditional indoor majors, Mac was the undisputed king, with a record of five wins, in the other: the WCT Finals at Dallas. He beat Borg,Lendl and Connors in three of his wins, and had easier final wins over Kriek and Gilbert ( in his 1989 win, his last shot at a major title).His 1983 final was epic, and so was his first title back in 1979, when he beat both, Connors and Borg, the first time somebody achieved it in years. He lost a four sets final three times, to Mecir in 87, to Connors in 80 and to Lendl in 82.He was owning Dallas.I think he played his best and sharpest tennis at the Reunion Arena. How could he do it? What made the difference? WHAT KEPT HIM GOING?
