– Maria Sharapova pulls out of the Qatar Total Open: The two-time champion has withdrawn citing the ongoing left forearm injury that has plagued her since the Dongfeng Motor Wuhan Open. The withdrawal is not much of a surprise if you’ve been paying attention. Sharapova told me in December that she had an eye on February as being a good time for a break.

“I’m going to go and take care of my forearm first,” Sharapova told reporters after losing in the quarterfinals at the Australian Open. “I think that’s really important. I’m going to go to Moscow [for Fed Cup], be part of the team. I don’t think I’ll be playing. Then I’m not sure.

“But I think this will be a time to just get myself ready for a long year. I don’t see myself playing anything before Indian Wells.”

– Other entry/withdrawal news: Agnieszka Radwanska has withdrawn from the Dubai Duty Free Championships citing the left leg injury she carried through the Australian Open. Lucie Safarova is also out of Dubai due to ongoing illness, though it looks like she’s already in Doha training for her return there. Safarova is the defending champion.

In their stead, No.3 Simona Halep and No.9 Petra Kvitova have taken wildcards into Dubai.

– Justine Henin jumps into the coaching pool: Ukrainian press are reporting that Henin will join Elina Svitolina’s team as a coaching consultant at the Slams.

– Tale of two juniors: Belinda Bencic and Daria Kasatkina are both 18-years-old and competed alongside each other on the junior ranks. Bencic made her jump to the senior tour first and is the top seed at this week’s St. Petersburg Ladies Trophy. Kasatkina is just starting her first full season on the tour. Both have been incredibly complimentary of each other’s games. Good to see their friendship endures:

– Injury sidelines Victoria Duval: Already in the early stages of her comeback from Hodgkins lymphoma, Duval underwent knee surgery this week for a torn meniscus.

⚠️ Earlier today, I underwent an arthroscopy on my knee to remove a tear in my meniscus. The onset of pain began several months ago

– The hottest Olympic qualifying races: Last week I put together an explainer on the qualifying rules for the 2016 Olympics in Rio de Janiero, Brazil. One notable rule: No country can send more than four singles players and two doubles teams. If a country has more than four players who meet all the eligibility criteria, the top four ranked get the nod.

This rule has little impact on countries that lack depth in the Top 100. Those players will be aiming for a Top 56 ranking on June 8th. But for four major nations — the United States, Germany, Russia, and Czech Republic — it creates a race within the race to qualify. Being Top 56 may not be enough. You also need to be one of the top four women from your country.

Here’s where things stand right now:

– April’s Fed Cup ties are set: The Fed Cup semifinals will feature the Czech Republics vs. Switzerland in Switzerland, while the French will host the Netherlands.

The World Group Playoffs are more complicated. The United States will have to fly to Australia just as the European clay season is set to begin. In another blockbuster tie, Germany will go to Romania, Belarus will go to Russia and Italy will go to Spain. As a reminder, the losing teams will be relegated to World Group II in 2017.
