The WTA’s Top 10 stayed in place after a week in Doha, which saw World No.3 Karolina Pliskova take home the title at the Qatar Total Open. But there were plenty of shifts for players right on the bubble, as a pair of former Top 5 players continued to chip away at their rankings.

Here are the biggest ranking movers this week after Doha:

Caroline Wozniacki +3 (No.18 to 15): Former World No.1 Wozniacki continued her comeback during the WTA’s Middle East Swing, storming to the final at the Qatar Total Open and posting wins over Monica Puig and No.6 Agnieszka Radwanska along the way.

The last time Wozniacki was ranked inside the Top 10 was in September 2015 (No.6), and with her strong showing in Doha she’s vaulted up to No.15 and closing in on a return to the game’s highest echelons.

“I feel like I’m playing really good tennis. I can still improve on some things,” Wozniacki told press after the final in Doha. “I’m really feeling positive and confident moving forward, and most of all I’m just trying to stay healthy.

“When I’m staying healthy, I can play great tennis. I can work really hard and improve my game. I’ve really put in a lot of work. It’s shown in the results. Hopefully I can keep up my level and keep improving.”

Samantha Stosur + 2 (No.21 to 19): Earlier in the season at Taipei City, Stosur halted a dismal trend of first round losses dating back to August 2016 that saw her ranking – and her confidence – take a dip. Now, the former Grand Slam champion is back inside the Top 20 after a run to her second consecutive WTA quarterfinal in Qatar.

Monica Puig +5 (No.47 to 42): Olympic champion Puig jumped up five spots to No.42 after an appearance in the semifinals in Doha. The run will do wonders for the Puerto Rican’s confidence: aside from regaining her world-beating form to put together dominating performances over Laura Siegemund and Daria Kasatkina, it’s the first semifinal Puig has reached since her fairy tale run to the gold medal at the Olympic tennis event in Rio.

Lauren Davis +9 (No.55 to 46): The 23-year-old American continued to back up the form that saw her claim her maiden WTA title earlier in the season at the ASB Classic in Auckland. Davis successfully qualified for the main draw at the Qatar Total Open, and went on to stun No.6 seed Elena Vesnina on her way to the quarterfinals, earning her first Top 20 win of the year.

Her season-long consistency has paid off, earning her a ranking jump to inside the Top 50, landing at No.46 – just three spots shy of her career high No.43.
