Serena wanted a child, can't fault her for that. The price she's paying is potentially not getting her 24th Slam, her best chance is at the French Open.
The media crush on Bianca is intense, she'll have no time to herself before preparing for Beijing. I wonder how she'll be received in the PRC? They probably don't want the point driven home that Canada is a success story. Too many rich Chinese are buying homes here, Xi and his Mao Princeling cohorts are going to be skittish. Apart from that, Bianca will have options for the start of 2020. As a Top 5 player, she may decide not to go to Auckland and concentrate on the Australian Open.
In the discussion among Legends (Becker, Wilander, McEnroe and Lendl) the question was asked: which player today most resembles their game. McEnroe said Denis Shapovalov, I agree. Shapo was adjusting to new muscle on his frame in 2019, he had a losing streak. He brought in Mikhail Youzhny as his coach in a tournament prior to the US Open, big improvement in his game. I like his chances in Australia.
Bianca will probably take up residence in The Bahamas - like Shapo has.
