“I didn’t think I’d see you guys again,” quipped Sandgren as he walked into his press conference. “I think patience was a big deal out there.
“I got a handful of looks on his serve. I had to just keep level-headed, keep holding onto my service games, doing the right things, and hopefully I could get a few looks.
“I was telling myself to stay calm, don't burn too much energy on stuff you don't need to, just focus on what you have to do.”
The 26-year-old had a real “pinch-me” moment conducting his on court interview.
“Obviously the first three matches were more than I expected. This one was about as hard-fought as I've ever had a match before. So that’s pretty neat.”
The world No.97’s reward is a quarterfinal clash with Next Gen prodigy Hyeon Chung, the conqueror of six-time champion Novak Djokovic.
“I played Chung two weeks ago,” added Sandgren, who fell to the South Korean in three sets in Auckland.
“He’s playing some amazing tennis, and that match kind of helped me raise my level. So that would be fitting to play him in the quarterfinals.”
