Orantes was one of the nicest guys on the Tour, and as Conchita rightly says, humble and classy champion. Here is an anecdote about him..
I saw him in 1983 at Monte Carlo. He pulled a big upset in the quarterfinals, defeating Yannick Noah (who won the French two months later). Noah was in complete control of the match until all of a sudden Orantes won the second set in the tiebreaker and served and volleyed his way to a win in the third set, at the age of 34.
Immediately after the hand shake, Noah stayed slumped in his chair, in total disbelief, with his head between his hands looking down at the ground for a good 6-7 minutes, with about 20 photographers gravitating around him, taking pictures.. Really eerie looking scene it was.. Completely quite, except for the clicking of the machines with this guy looking like he is about to commit a suicide on a chair, and photographers giving him no breathing room and taking picture after picture 5-6 feet away from him on the court.. It was on an outside court and most people were already gone after the handshake. It was such a bizarre 6-7 minutes that 2 months later when Noah won Roland Garros he was even asked by one of the press people if what went through his head in Monte Carlo after his loss to Orantes put him back in the right track to win RG.
Back to that scene... It was finally Manolo who was about to walk off the court, and looked back and saw the ridiculous scene taking place, who came back and saved Noah basically. He walked back there, told a few of the photographers 'gently' to back off, and consoled Noah and told him to get his bag and walk off the court with him, you could see as he was walking off that Noah had been crying that whole time.
