Upset alert on Ashe as fourth-seeded Dominic Thiem has dropped the first set to Italy’s Thomas Fabbiano. The world No 87 is no stranger to early-round upsets, having taken out Tsitsipas at the All
England Club this summer. Meanwhile on Armstrong,
Wimbledon champion Simona Halep is off to a promising start against the
American Nicole Gibbs, nabbing an early break to race ahead in the opening set. 8.29pm BST
Tsitsipas’s section of the draw is even more wide open than it was before. He’s out. No 10 seed Roberto Bautista Agut is out after a highly entertaining five-set loss to Mikhail Kukushkin. That leaves only two seeds remaining in the section: No 24 Matteo Berrettini and No 28 Nick Kyrgios.
