Nice, today, to see Cilic persevere in his 5 set / tie break against Rublev ... life in the old dog yet!
Agree, though in tennis terms now not quite as old a dog as many. Nadal is 2 years and 4 months older.
He's joined in the semi finals by Ruud who whioe having reached a final of a Masters tournament is definitely making a significant breakthrough here.
In the women's, Swiatek continues her winning streak, and will face Kasatkina in the semi finals. Kasatkina, is after Swiatek, the highest ranked player left in the women's, having been ranked 20 at the start of the tournament.
