(CNN) Stan Wawrinka considers himself to be a cut below the "Big Four" in tennis. But when it comes to toppling Novak Djokovic lately at grand slams -- the leading member, on current form, of the illustrious quartet that also includes Roger Federer, Rafael Nadal and Andy Murray -- Wawrinka has no equal. 1, 6-7 (1-7) 6-4 7-5 6-3, in a bruising US Open final to win a third grand slam title. But in allowing Wawrinka to find his way into the first set, the match veered in a different, and for Djokovic, displeasing direction. Wawrinka possesses thunderous strokes able to penetrate the perhaps unparalleled defense of Djokovic, with his versatile one-handed backhand attracting the majority of the plaudits.
