Iga probably liked the the quiet, maybe. I suppose when you play as well as she usually does, you don't need that push that the crowd give you.
I did know Rafa was an ambassador, and I have to say, I found that a strange move too. A disappointing one, if I'm honest. Especially given he was obviously coming to the end of his career, has his own foundation- and if I was him, I'd be wanting to do things closer to home and that stick with his charities. It's not really as though he needs the money.
All those involved are saying they think it will build interest in the sport in the country, and it all has to start somewhere- but I'm not sure.
