The weather forecast is for a cloudy but less humid day in New Haven.
Petra Kvitova is a four-time finalist here, winning on three of those occasions - in 2012, 2014, and 2015.
The Czech edges her head-to-head with Carla Suarez Navarro, leading 6-5, and winning their most recent meeting, in Toronto last year.
Aryna Sabalenka is the youngest singles player in the main draw, at the age of 20.
Sabalenka has never played Belinda Bencic before.
Second seed Caroline Garcia's best performance here was in 2015, when she reached the quarterfinal but lost to Caroline Wozniacki.
Ekaterina Makarova has never lost to Julia Goerges, beating her in the Washington final last year, and also in the Australian Open Round of 16 three years ago.
