French Open tennis. Seems like the winners, (eg Rafa Nadal who has one of the greatest sporting records in any sport, anywhere there), consistently hit ground strokes from the baseline, back over the net and deep enough in play. From that point the opponent self-destructs.

Ok differs from wimbeldon where guys play Hamlet while playing in the final (Kyrios, Becker, McEnroe, etc. etc.) and can win doing it with outrageous aggression and magic winners, but the French Open is certainly "High Level" Rafa at the French? How many matches was his longest winning streak? 36 matches, 5 titles in 6 years? Unfathomable sustained excellence.
