It seems Caroline Wozniacki should put a revolving door on her coaching stable. After dismissing Thomas Hogstedt, who was alongside her since only November, the freshly engaged star will now work with fellow Dane Michael Mortensen, who previously aided her in her junior career. Turns out Hogstedt went on holiday after the Aussie Open, and she subsequently unloaded him.

So, in this episode of As the Coaching World Turns, let's beg the question: With whom should Hogstedt, who coached Maria Sharapova through her claim on the French Open title in 2012, work with next? Who would make for an enticing match-up with him?

Whoever that is, that player—if a WTA pro—is going to have a lot of strategic fodder to take into her next matches against Sharapova and Wozniacki.

The Spin's pick: Agnieszka Radwanska. It's past time that her game and her results reach the next level: A Grand Slam title. As she showed in her cagey Australian Open play—particularly against No. 2 Victoria Azarenka—before submitting both meekly and anticlimactically to Dominika Cibulkova, she's got the game and the tactics to go the distance. Sure, a draw would need to align for her much like it basically did Down Under. That said, it can be done. The tennis gods know full well that just that happened at both the 2013 Wimbledon and 2014 Aussie Open—two of the past three majors.
