Coco Gauff is still in and Naomi Osaka is out following Day 1 at Wimbledon.
The 15-year-old Gauff showed poise and power in a 6-4, 6-4 stunner against seven-time Grand Slam tennis champion Venus Williams.
The 39-year-old Williams was the oldest competitor in the women's bracket before falling to the youngest competitor to qualify at the All England Club in the professional era.
Meanwhile, the second-seeded Osaka continued her recent downward spiral by dropping her first-round match to Yulia Putinseva, 7-6, 6-2.
Osaka is the reigning U.S. Open and Australian Open champion, but her slump dropped her from the top of the WTA rankings last week.
