Carreno Busta overcame Shapovalov's power as well as a back injury late on; and dug deep to claim a 3-6, 7-6(5), 7-6(4), 0-6, 6-3 to reach this stage for a second time at the US Open.

”I’m destroyed, but I’m very happy. It’s incredible to be back in the semi-finals,” Carreno Busta said to ESPN’s James Blake after the match. “I think I’m very comfortable on these courts.

”I think the past months during quarantine was very tough for everyone. I worked very hard with my coach. When you work hard; normally the results arrive. Maybe not in the first tournament, but I’m very lucky to be in the semi-finals."
