No. 42 Aslan Karatsev, +72 (Career High)
The Russian rose 72 places to break into the Top 50 of the FedEx ATP Rankings for the first time at No. 42 after a run to the Australian Open semi-finals (l. to Djokovic). The 27-year-old, who qualified for his first Grand Slam championship and beat eighth seed Diego Schwartzman, No. 18 seed Felix Auger-Aliassime and No. 20 seed Grigor Dimitrov in Melbourne, was ranked No. 262 just 12 months ago. Karatsev, who was the first man in the Open Era to reach the semi-finals on his major championship debut, joined Daniil Medvedev and Andrey Rublev in Russia’s ATP Cup-winning team earlier this month.
No. 3 Daniil Medvedev, +1 (Career High)
The Russian claimed five straight-sets wins en route to his second Grand Slam championship final (also 2019 US Open), where he saw his 20-match winning streak come to an end at the hands of Novak Djokovic, who won 7-5, 6-2, 6-2. The 25-year-old, who beat Top 10 opponents Rublev and Stefanos Tsitsipas to reach the Australian Open title match, rose one spot to a career-high No. 3.
