Yesterday I asked me this question after the first set of the Federer-Raonic match, because nobody was anywhere near a break point. I thought it would go on this way, but then Federer broke right at the beginning of the second set.
I think the most famous match with no realised breaks was the QF of the US Open in 2001 between Sampras and Agassi. But there were opportunities (Sampras had 6 and Agassi 3).
So I wonder if there was a match with zero break points either in the Open Era or in notable matches before 1968. Maybe there is even an example in the women's game, but I don't think so because of the weaker serve.
