Felix Auger-Aliassime set to break into Top 5 on ATP rankings following run at ATP Finals

Felix Auger-Aliassime is going to be a Top 5 player for the first time in his career when the new ATP rankings come out on Monday.

The Canadian, who will play Carlos Alcaraz in the second semifinal at the ATP Finals on Saturday night, secured his big debut after Alex de Minaur fell to Jannik Sinner in the first semifinal of the day.

Having previously gone as high as No. 6 in 2022, Auger-Aliassime is currently up to No. 5 on the ATP's official live rankings, and De Minaur was the only player left who could pass him, so his spot in the elite is secured. He could even go as high as No. 4 if he wins the title.

Whatever happens, he'll be the second Canadian man—and fourth Canadian player overall, male or female—to break into the Top 5 since ATP and WTA rankings began in 1973 and 1975, respectively.

CANADIANS TO REACH TOP 5 ON ATP OR WTA RANKINGS (since 1973 and 1975):

• Eugenie Bouchard [WTA Top 5 debut in 2014, career-high No. 5]
• Milos Raonic [ATP Top 5 debut in 2015, career-high No. 3]
• Bianca Andreescu [WTA Top 5 debut in 2019, career-high No. 4]
• Felix Auger-Aliassime [ATP Top 5 debut in 2025, career-high TBD]

Auger-Aliassime will also become just the sixth man born in the 2000s to break into the Top 5, a list that includes the current No. 1 and No. 2 players on the ATP rankings, Alcaraz and Sinner.

PLAYERS BORN IN THE 2000s TO REACH TOP 5 ON ATP RANKINGS (listed in order of when they debuted in Top 5):

• Carlos Alcaraz [born in 2003, Top 5 debut in July 2022]
• Holger Rune [born in 2003, Top 5 debut in August 2023]
• Jannik Sinner [born in 2001, Top 5 debut in October 2023]
• Jack Draper [born in 2001, Top 5 debut in May 2025]
• Ben Shelton [born in 2002, Top 5 debut in November 2025]
• Felix Auger-Aliassime [born in 2000, Top 5 debut in November 2025]

Going into the ATP Finals this week there was a heated battle for the No. 5 spot on the ATP rankings, with Nos. 5 through 9—Ben Shelton, Taylor Fritz, Alex de Minaur, Auger-Aliassime and Lorenzo Musetti—separated by a mere 130 ranking points, 3,970 to 3,840.

But Auger-Aliassime was the only one of the group to get two round-robin wins this week, against Shelton and Alexander Zverev, and he'll now secure at least No. 5 no matter what happens from here.

And his ranking breakthrough should come as no surprise given his recent results—he's won 24 of his last 30 matches, reaching the quarterfinals or better at his last seven tournaments in a row, including semifinals at the US Open and now the ATP Finals.

He actually went into Flushing Meadows ranked No. 27 in the world—now, a little over two months later, he'll be a Top 5 player.
