Professional career

2015–16: Challenger and ranking records

In March 2015 at the Challenger de Drummondville, Auger-Aliassime became the youngest player in history to qualify for an ATP Challenger main draw at 14+1⁄2 years old. He defeated compatriot Jack Mingjie Lin, former world No. 67, Chris Guccione, and world No. 433, Fritz Wolmarans, to do so. He, however, was forced to withdraw before playing his first-round match due to an abdominal strain. With the points earned, Auger-Aliassime once again made history as the first player born in the 2000s to have an ATP ranking. At the Challenger de Granby in July 2015, he qualified for his second ATP Challenger main draw with victories over fellow Canadian Jack Mingjie Lin and world No. 574, Jean-Yves Aubone. He won his opening round in straight sets over world No. 493 Andrew Whittington, becoming the youngest player to win a main-draw ATP Challenger match. In the next round, he scored an upset over world No. 205, Darian King, in straight sets. He was stopped by world No. 145 Yoshihito Nishioka in three sets in the quarterfinals. After his run to the quarterfinals, Auger-Aliassime became the youngest player ever to break the top 800 on the ATP rankings at No. 749.

In September at the Copa Sevilla, he won his second ATP Challenger title of the season after defeating former world No. 56, Íñigo Cervantes, in the final.
