I'm sat next to the second ref position this weekend for the World Cup. March 23-27 - WGC-Dells Technologies Match Play - Austin Country Club, Austin, Texas September 15-18 - DS Automobiles Italian Open - Marco Simone GC, Rome, Italy Prior to this week Raducanu - the US Open champion in September - had never won a WTA Tour level match, but she had made it two in three days with victories over Ana Bogdan and Polona Hercog before Kostyuk proved a bridge too far.
