"Weird ending today but I'm through" says Felix Auger-Aliassime after Alcaraz retires in 2nd set

Felix Auger-Aliassime is through to the US Open semifinal after Carlos Alcaraz retired in the 2nd set.

The Canadian is enjoying a fantastic event and he became the youngest player since Juan Martin Del Potro to advance to the final four at Flushing Meadows. His spot in the semifinal came after Carlos Alcaraz retired in the 2nd set but leading up to that Auger-Aliassime was completely in control of the match. He said:

"It's an amazing milestone. It's been a fantastic tournament for me. Of course, it was a weird ending today. But in the end, I'm through. I'll have a chance to play on Friday against one of the best players in the world right now to have a chance to be in my first Grand Slam final. It's amazing, I'm happy I'm through and I'll try to win the next one."

The retirement came as a surprise to the crowd as well as Auger-Aliassime. Alcaraz looked fine during the match albeit his level was nowhere near the previous two rounds. The groundstrokes did not work as he committed 16 unforced errors in 13 games. On the retirement Felix said:

"No, I didn't [know anything was wrong] until he called the physio. I don't know what happened, clearly, but it's unfortunate. I didn't see it coming. He's such a good player. You guys were amazing again tonight. I thought we were putting on a good show."
