So's her Canadian counterpart, the just-turned-19 Annie Leyla Fernandez.
Been knocking off top-ranked rivals all week.
Could we have an all-teen final at Flushing Meadows?
I recall two years ago meeting up with the dean of Canadian tennis journalism, Tom Tebbutt, during a quiet moment in the qualifying rounds for the Canadian event on the WTA tour, the Rogers Cup, here in Toronto.
He had some notes out and the daily printout of the Order of Play and as I passed by from covering some hapless Yank chick getting dusted by a Chinese player, I glanced down to look at his schedule sheet. We struck up a conversation and he told me to go cover Fernandez.
He said that she was very young and a relative unknown, but he had spotted something in her game that suggested she was destined for bigger and better things.
Off I went and she put up a spirited fight in a losing effort to a much more experienced rival. All I cared about was making good pictures and she provided them.
But there was my first introduction to her and she has steadily grown into a strong contender. I don't know much about Raducanu's background, but fascinating to see children of immigrant parents rising up against the odds, against the established order, and now excelling on the world's biggest stages.
