Borg the Martian. You can forget every other player. Borg was a mental freak who never even objected to outrageous bad calls. There was one lone exception. At the year-end Masters in MSG against McEnroe, at a crucial point in a tiebreak, Frank Hammond overruled a good call on the baseline in favor of Mac. Borg calmly walked to the chair and softly complained refusing to play for five minutes or so. Everyone was shocked. Borg lost the tiebreak but won the match.
That's the incident I was referring to, but I thought it was Stockholm. But you're right, it was New York, Masters. There's a clip here:
Amusingly weird to see Mac calmly fiddling with his strings while Borg has (what for him was) a massive meltdown. There are no histrionics from BB, but if looks could kill.... Can't be a coincidence it was in a match against Mac, either, the one player who freaked Borg out. It's testament to his immense mental strength that Borg still went on to win this match, on probably McEnroe's best surface.
Also nice to see the umpire enforcing time rules against the game's biggest star.
I wonder, does this one incident mean we have to give the title to Laver? Did Laver ever even question a call?
