American teenager Learner Tien has climbed to a career-high No. 24 in the ATP rankings following his quarterfinal run at the Australian Open. Other young players like Elliott Spizzirri and Luciano Darderi also made significant gains, while Lorenzo Sonego dropped sharply. The rankings update highlights the tournament's impact on the top 100.
The Australian Open, now in its second week in Melbourne, has already reshaped the ATP top 100 with notable movements reflecting strong performances and early exits.
Learner Tien, the young American tipped as a future star, maximized his opportunity by reaching the quarterfinals. His composed play and shot tolerance led to key wins, including a statement victory over Daniil Medvedev. Building on last year's fourth-round appearance, Tien's surge has pushed him to a career-high No. 24.
Elliott Spizzirri also benefited, rising 14 spots from No. 85 to No. 71. His fearless shot-making and improved consistency shone through, marked by being the only player to take a set off world No. 2 and defending champion Jannik Sinner.
Italy's Luciano Darderi reached the round of 16, translating his clay-court strengths to hard courts with physicality and better point construction. This effort earned him a career-high No. 23.
Lorenzo Musetti showed promise with aggressive baseline play and variety, troubling elite opponents. However, he retired during his quarterfinal against Novak Djokovic due to injury, limiting his ranking push but boosting his confidence.
On the downside, Lorenzo Sonego tumbled around 20 places after an early exit, unable to defend last season's quarterfinal points. This underscores the Grand Slam's unforgiving nature for point defense.
With semifinals ahead, further shifts are expected as the tournament favors the bold and reveals emerging talents.
