Angelique Kerber (+4, No.6 to No.2): 2016 Australian Open champion finished the fortnight ranked the highest of the WTA's movers and shakers, moving up to a career-high ranking behind runner-up Serena Williams.
Carla Suárez Navarro (+3, No.11 to No.8): Suárez Navarro returned to the Top 10 and her career-high ranking after reaching the second week Down Under for the first time since 2009, when she also made the quarters.
Zhang Shuai (+68, No.133 to No.65): The new Chinese No.1 made the largest leap of the bunch; coming to Melbourne without ever having won a Grand Slam main draw match, the qualifier won four in a row Down Under, beating former then-World No.2 Simona Halep in the first round.
Anna-Lena Friedsam (+30, No.82 to No.52): Though her tournament ended with injury and tears at the hands of eventual semifinalist Agnieszka Radwanska, Friedsam made the second biggest jump after reaching her first career Grand Slam second week.
Johanna Konta (+19, No.47 to No.28): The Australian Open semifinalist was the first from the UK to reach that stage sincs Sue Barker in 1977, and though she fell to eventual champion Kerber, Konta became the highest-ranked Brit since Laura Robson was ranked No.27 in 2013.
Kateryna Bondarenko (+19, No.92 to No.73): a former US Open quarterfinalist who came back to tennis 18 months ago after having a baby, the younger of the Bondarenko sisters moved back into the Top 75 for the first time since 2012.
Margarita Gasparyan (+16, No.58 to No.42): The most successful of this next generation of young Russians made the round of 16 and enjoyed the biggest jump of her cohort to a career-high ranking. Garparyan also becomes the No.5 Russian behind Ekaterina Makarova, a particularly notable stat given that the Olympic team will only take the Top 4 players from a country with multiple athletes ranked in the Top 56.
Elizaveta Kulichkova (+14, No.109 to No.95): The former Australian Open junior champion made the third round at her favorite tournament, upsetting Andrea Petkovic to return to the Top 100 and land one off her career-high of No.94.
Daria Kasatkina (+8, No.69 to No.61): Kasatkina started the year with a win over Venus Williams in Auckland; though she couldn't replicate the feat against sister Serena in the third round in Melbourne, she nonetheless hit a career-high just outside the Top 60.
Daria Gavrilova (+6, No.39 to No.33): The Moscow-born, Melbourne-based Aussie got within striking distance of the seeds after making an exciting run to the fourth round of her home Slam, beating former No.2 Petra Kvitova en route.
