It took Roger Federer just over an hour to storm past 23rd seed Kyle Edmund of Britain 6-1, 6-4, moving closer to his sixth Indian Wells title.
Afterwards, in a clear indication of her confidence, Andreescu said: "For me, the sky's the limit".
"That's something really special and (I'm) just happy to be part of it".
What was unexpected was a piece of honesty.
"He didn't have the best start, so that cost him the first set", Federer said.
"The Rocket and the Pistol".
"He's been around for so many years and he doesn't really get overwhelmed by the occasion of playing on center court", he told reporters.

World number two Nadal overpowered Serbian qualifier Filip Krajinovic 6-3, 6-4 to book his quarter-final berth in one hour and 26 minutes. Novak Djokovic and Naomi Osaka, the world's top-ranked players, lost in straight sets.
"The difference between players is not huge". When asked about the potential for another clash with his rival, Federer said he was exciting for the opportunity to meet Nadal yet again. "Is true that for the last 10 years didn't happen very often".
Neither Federer or Nadal have dropped a set in their three matches at Indian Wells, a tournament Federer has won five times and Nadal three. Maybe because of the conditions, [it was] windier out there today.
Next up for Nadal is Karen Khachanov, who defeated John Isner 6-4 7-6 (7-1).
Kecmanovic became the first lucky loser to reach the last eight at Indian Wells since the ATP's Masters 1000 series launched in 1990.
"It will be amusing that somebody other than Novak is still in", he said of his famous countryman.
Kecmanovic, ranked 130th in the world, had taken the first set against Yoshihito Nishioka 6-4 when the 74th-ranked Japanese retired because of injury.
Kecmanovic next plays 13th-seeded Canadian Milos Raonic, who beat Jan-Lennard Struff 6-4, 6-3.
