So Dinara Safina will be the new world number one.
A more engaging and entertaining personality you would struggle to find in women's tennis at the moment, and reaching the pinnacle of such a competitive sport is something to be applauded.
April 20th will also be a magnificent day for her family as she will match brother Marat, who became the ATP number one on 20 November, 2000, making them the first brother-sister duo to top the rankings.
Their parents and everyone at the Spartak tennis club in Moscow can reflect on a job very well done.
But… it is a shame that Safina will take over at the top of the game just when her form has tailed off.
Runner-up finishes in Sydney and Melbourne at the start of the year have not been backed up and she will be keen to get back to Europe's clay courts, where she prospered last year.
And the key for any player with aspirations to dominate the game and make their mark in the history books is to win Grand Slam titles, something the 22-year-old has yet to do.
Jelena Jankovic had to answer similar criticisms when she reached number one last year and it is telling that, on hearing the news on Wednesday, Safina herself said: "There’s no question that while I am very proud of my results over the past year, I would have liked to reach this achievement in a different manner.
"I hope to prove to everyone over the coming months that I merit the honor of being world number one."
Safina made progress in the last year by reaching the finals of the French Open and Australian Open, but played poorly in both.
So will she relish the challenge of improving on that and go from strength to strength, or will she be a mere footnote in this list of WTA world number ones....?
