After losing in the semi-finals to Andy Murray, Milos Raonic is expected to be biggest mover among the top 15 on the ATP Tour, improving three places to No. 11.STRINGER/Reuters
Angelique Kerber's upset win over Serena Williams at the Australian Open and Milos Raonic's second Grand Slam semi-final appearance will ensure they're the biggest movers among top players in projected rankings to be released this week.
Seventh-seeded Kerber's three-set win on Saturday, which prevented Williams from securing her 22nd major title, is expected to result in the German player moving to No. 2 on the WTA Tour.
The rankings, expected to be released Monday, should show Williams at No. 1, Kerber at No. 2 and Simona Halep, who lost in the first round at Melbourne Park, dropping one spot to No. 3.
"She's had a great month," Williams said of Kerber. "She got to the finals in Brisbane. She won here. So, yeah. I was surprised and really happy for her. I'm like, 'Whoa, No. 2.' What's after 2 is 1, so I guess I better be careful."
Agnieszka Radwanska, who lost to Williams in the semi-finals, remains at No. 4, while Garbine Muguruza drops two places to fifth.
Maria Sharapova, the 2015 finalist who lost to Williams in the quarter-finals this year, moves to sixth, followed by Flavia Pennetta, Carla Suarez Navarro, two-time Wimbledon champion Petra Kvitova and Lucie Safarova.
Safarova did not play in Melbourne because of a bacterial infection.
On the men's side, Raonic, the 25-year-old Canadian who lost in the semi-finals to Andy Murray, was expected to be biggest mover among the top 15 on the ATP Tour, improving three places to No. 11.
It was Raonic's second major semi-final after losing to Roger Federer in the final four at Wimbledon in 2014.
Quarter-finalist David Ferrer moved to sixth place in a switch with Tomas Berdych, who slips down to eighth.
The top five remained unchanged. Six-time champion Novak Djokovic and five-time losing finalist Murray would have remained 1-2 regardless of the result of their Sunday final, which Djokovic won in straight sets.
Federer, who lost to Djokovic in the semi-finals, remains at No. 3, Stan Wawrinka at No. 4 and Rafael Nadal, a first-round loser to Fernando Verdasco in Melbourne, rounds out the top five.
Following Ferrer is Japan's Kei Nishikori, unchanged at No. 7 after losing to Djokovic in the quarter-finals.
Jo-Wilfried Tsonga moves to No. 9, replacing fellow Frenchman Richard Gasquet, who drops to 10. Following Raonic is No. 12 John Isner of the United States.
