It was a queasy week in women's tennis.
There were three retirements at the Qatar Open (Jankovic, Muguruza and Dulgheru) and top-seeded Maria Sharapova, complaining of a gastrointestinal disorder, granted a walkover to Caroline Garcia in the Acapulco semifinals.
One more week with two smaller events before the heavy hitters gather at Indian Wells.
Here are the up-and-down movers from last week's two events:
No. 2 Maria Sharapova: She buzzed through her first three matches but couldn't step on the court for the semifinal in Acapulco. Rest assured, she'll be ready for action later next week in the California desert. She's a two-time Indian Wells champion, winning in 2013 and 2006.
No. 4 Petra Kvitova: Doha's No. 1 seed fell to Carla Suarez Navarro 3-6, 6-0, 6-3 in the quarterfinals. Navarro, an up-and-coming Spaniard, showed more gumption under duress than the Czech Republic player -- something that shouldn't happen to a two-time Grand Slam champion.
No. 5 Caroline Wozniacki: There is no shame in losing to Victoria Azarenka -- even if she isn't quite at full strength yet. But the manner in which Wozniacki lost (6-3, 6-1) was disturbing.
No. 8 Agnieszka Radwanska: A disappointing start to the season for Radwanska. She lost to Venus Williams in a three-set quarterfinal in Doha. This after losing to Venus in the fourth round of the Australian Open. She's also fallen twice this year to the ascendant Garbine Muguruza.
No. 10 Andrea Petkovic: After a nice flurry, and emerging from Antwerp with the title, the German has lost two of her past four matches. As the No. 6 seed in Doha, she scraped past Kirsten Flipkens and avenged a Dubai loss to Zarina Diyas. But in the quarters, she fell to unseeded Lucie Safarova without much of a fight 6-2, 6-1.
No. 11 Lucie Safarova: It's quietly been a nice year for the Czech, who won her sixth career tournament this past weekend, at the Qatar Open. Safarova beat Azarenka rather comfortably in the final, which was somewhat of a surprise considering she'd lost all six of her previous matches against the Belarusian. Safarova also captured the Australian Open doubles championship with partner Bethanie Mattek-Sands back in January.
No. 13 Carla Suarez Navarro: Another nice week for the 26-year-old Spaniard. She handled up-and-coming Karolina Pliskova in the second round, then outlasted top seed Petra Kvitova in the quarters, winning in three sets. She fell to Safarova in the semifinals 6-3, 6-2.
No. 17 Venus Williams: Another solid effort from the 34-year-old. She won her first three matches in Doha, the third a 6-4, 1-6, 6-3 victory over No. 4 seed Radwanska. Azarenka was just too strong in the semifinals.
No. 38 Victoria Azarenka: She was an unseeded wild card at Dubai, but the 25-year-old from Belarus is beginning to resemble the two-time Grand Slam champion she is. After a horrific year of injuries, Azarenka is coming back. She reached the fourth round of the Australian Open and last week made the finals in Dubai, beating Caroline Wozniacki for the second time this year and taking out Venus in a three-set semifinal. Azarenka lost to Safarova in the final.
