One minute, Jessica Pegula was dismantling Madison Keys' title defense with a clinical 6-3, 6-4 victory.
The next, the ousted champion was promising her full support for Pegula as she heads into an all-American quarterfinal against fourth-seeded Amanda Anisimova.
''I don't think she needs any sort of pep talk from me,'' said Keys, who does a podcast with Pegula and is a close friend. ''I think she's sure of her game and how she's playing. We'll just be cheering her on.''
The Grand Slam Keys won a year ago was her first, which brings some peace even in defeat. At least she has one as she turns 31 next month.
Pegula, on the other hand, has yet to win one. She turns 32 next month. She lost the U.S. Open final in 2024 to Aryna Sabalenka and is into the Australian Open quarterfinals for the fourth time. She's lost the previous three.
''I'd say it feels way better losing and still being defending champion,'' the ninth-seeded Keys said. "It's not like the world is ending because I lost today.
''When we play 11 months out of the year, and you play almost every single week — I mean you can't maintain the roller-coaster of the highs of winning and the lows of being devastated every single week," Keys added.
Pegula, seeded No. 6 here, said facing a friend was no big deal. And ditto about facing another American in the quarterfinals.
