Simona Halep continues her campaign to reclaim her World No.1 spot - and is now hot on the heels of Naomi Osaka as she sits proudly at World No.2.
The Romanian made the final of the Mutua Madrid Open - and reached the semifinals without dropping a set, including a 7-5, 7-5 victory over ninth seed Ashleigh Barty.
Kiki Bertens' irresistible form proved too much in the final - but Halep is certainly pleased with her progress in the clay season so far.
She now returns to the No.2 slot after two weeks ranked as World No.3 - and has not been out of those top three spots all year.
In fact, the last time she was lower than third in the world was almost two years ago - when she was ranked as World No.4 on May 29, 2017.
Bertens also gets a rankings boost this week - up three places and into the Top 5, sitting at a new career high of World No.4.
Here are some of the week's other most notable rankings movers.
Petra Martic (+8, No.36 to No.28): Now the World No.28, the Croatian stunned the fans when she beat home favorite and two-time Grand Slam champion Garbiñe Muguruza in the first round.
Kateryna Kozlova (+19, No.85 to No.66): The Ukrainian closes in on her career-high after a great week in Spain, which included a win over fifth seed Karolina Pliskova, 7-5, 2-6, 6-4.
Vera Zvonareva (+3, No.82 to No.79): Another great week for the former World No.2, who fought her way through qualifying in Madrid to secure a first-round tie against the USA's Danielle Collins.
Anna Karolina Schmiedlova (+17, No.109 to No.92): The 24-year-old makes her way into the Top 100 after battling through the Madrid qualifiers, and following that up with a straight-sets defeat of Elise Mertens in the first round.
