Wilander was one of those players who could get blown off the court in a 'smaller' event by a player ranked 150 in the world and then 3 weeks later hold up a grand slam trophy, beating that same player en route to the GS final. I always got the impression when watching him play that he wasn't too fussed about the non slams. But in the grand slams, boy he was tough. He would beat you in the matches that count but still have a lising H2H record against you.
That is all.
