Angelique Kerber is on her way back up the WTA Rankings following her campaign at the BNP Paribas Open.
The former World No.1 had the chance to rise to second in the rankings had she lifted the title - but having finished as runner-up, she moves up four places to No.4.
Instead, it's Petra Kvitova who moves up one place to the World No.2 spot. The Czech lost in the first round in Indian Wells, defeated 4-6, 7-5, 6-4 by Venus Williams, but nonetheless steps up to slot in just behind Naomi Osaka in the rankings.
Here are some of the week's other most notable rankings movers:
Garbiñe Muguruza (+3, No.20 to No.17): The Spaniard reached the Indian Wells quarterfinals, where she lost to eventual champion Bianca Andreescu, but beat seventh seed Kiki Bertens along the way as well as enjoying a win over Serena Williams, who was forced to retire from their Round of 32 clash.
Belinda Bencic (+3, No.23 to No.20): The Swiss returns to the Top 20 after a great fortnight in Indian Wells, where she took out World No.1 Naomi Osaka in the Round of 16, winning in straight sets, following that with a hard-fought win against fifth seed Karolina Pliskova in the quarterfinal, 6-3, 4-6, 6-3.
Victoria Azarenka (+2, No.49 to No.47): The two-time Grand Slam champion continues to make inroads into the Top 50 despite consistently tough draws. In Indian Wells she played out a classic second-round encounter with old foe and tenth seed Serena Williams, losing 7-5, 6-3.
Ajla Tomljanovic (+4, No.44 to No.40): It's a career high for the Australian, who battled hard against ninth seed Aryna Sabalenka in the Indian Wells Round of 32, falling in three sets.
