That's a far cry from 2016 when Raonic made it to the final of Queen's before losing to Murray.
Before taking her seat next to Murray's mum, Judy in the royal box, the Duchess took time to meet with the tournament's ball boys and girls and hear about their experiences on the court.
"I'm getting closer but you need to win these matches to really move up the rankings", said Edmund. "There was time for the court to dry up before we came out again".
"Thanks for the advice about not serving 20 double-faults", the Kzakh said.
'I really don't want to miss seeing those changes. He and Brown - who came from behind to beat the Portuguese João Sousa in four sets - have played only once, when Murray defeated him at the US Open seven years ago. "I think that he's found that maybe there's a benefit to streamlining his approach, not only on the court but especially off the court".
The reigning champion has been struggling with a hip injury which has hampered his pre-tournament preparations.
But ahead of the 30-year-old's clash with lucky loser Alexander Bublik, Judy admitted she felt helpless to influence the occasion and could only hope for the best.
"Maybe it adds a little bit extra pressure, especially at this slam with the way the scheduling is, that you're the first one out there on Centre Court".
Murray had been hampered by a hip injury, which had prevented him from playing two exhibition matches last week, however he had little trouble reaching the second round.
"I'm going to have to try to play the same way [he did against Nadal], play aggressive". I know Dustin pretty well.
Bublik could only shake his head and applaud, and a forehand into the net from the Kazakh on the next point gave Murray the set 6-4.
"The Duke and Duchess are very much looking forward to this tour and are delighted with the exciting and varied programme that has been put together for it", the Kensington Palace spokesperson said, E!
The Duchess also met officials and players, including women's world No 10 Agnieszka Radwanska and men's world No 8 Dominic Thiem, when she arrived at the grounds.
"That's why you're so relaxed!", she said, according to the DailyMail.com. "I don't see why he can't make it through to the semi-finals, but I also expect all the "Big Four" to go deep", Rusedski wrote in a column for The Telegraph after the match.
For Canadian tennis fans, though, all eyes will be on Raonic to see if he can recapture the magic of a year ago.
