The 19-year-old Canadian was tested across nearly two hours by Seppi, the player who stunned him in the opening round at Roland Garros earlier in the season. Auger-Aliassime earned his revenge with 25 winners, including nine aces, and five service breaks from 12 opportunities.
Felix Draws On ‘Champion Mentality’ In Washington
Auger-Aliassime, who arrived in Washington, D.C. at a new career-high World No. 15 in the FedEx ATP Rankings, improved to 24-15 on the season with the victory. Coached by Frederic Fontang and Toni Nadal, Auger-Aliassime will be looking for his third tour-level final of the season after reaching the championship match in Stuttgart and Melbourne.
He needed a couple of games to gain his footing in Washington, D.C. against Seppi. By the time the 19-year-old found his best tennis, Auger-Aliassime was already down a double break and 5-1 in the opening set against the Italian veteran. Auger-Aliassime raised his level after saving two set points in the opening set, starting the second with a 3-0 lead.
The Canadian improved his first-serve points won from 65 per cent (11/17) in the first set to 85 per cent in the second set and 89 per cent in the third set. That kept the Italian on the back foot, and Auger-Aliassime earned unforced errors regularly as he continued to apply the pressure in the later stages of the match.
