Both the US Open men's and women's brackets are through the first rounds: 128 entered, only 64 remain.
On the men's side, many of the top contenders have already been eliminated. No. 4-ranked Novak Djokovic was eliminated by unranked Mariano Navone. No. 10 Arthur Fils fell victim to Stefanos Tsitsipas as well.
As many people say, majors often bring some crazy, unexpected results, and that's certainly been the case for the men so far.
The women's bracket only saw one member of the top 12 get eliminated with No. 12 Belinda Bencic falling in three sets. That said, there are likely many upsets to come as we get deeper in the tournament and the pressure starts to mount.
Here's everything you need to know for Day 4 or the second round of the 2026 US Open:
