From Angelique Kerber stating she's not thinking about motherhood yet to David Goffin insisting he feels more like "20" than 30, winning players provided plenty of interesting insight after their matches at Flushing Meadows on Friday.

The Australian will meet Andreas Seppi for a spot in the semifinals after prevailing in three sets over the top seed on Thursday in Long Island.

The Aussie will face Rafael Nadal in a must-see second-rounder after his 7-6 (4), 3-6, 7-6 (10), 0-6, 6-1 win.

The 30-year-old Frenchman was contesting his first final of the season, his seventh overall.

The 25-year-old is the last man standing for Australia at the French Open, reaching the third round of a Slam for the first time.

“Playing all of those Challenger matches in 2018 gave me a lot of confidence. Then towards the end of the year I made a final in Calgary and I won two tournaments in a row."

The 22-year-old qualifier completed a three-set win on Saturday (over Jordan Thompson), but fell in the semifinals later in the day (against Casper Ruud).

The Austrian, playing solidly all week, had only won three matches coming into the Desert.
