NEW YORK—Thursday night will see the women's semifinals take center stage inside Arthur Ashe Stadium. Serena Williams takes on Anastasija Sevastova, while last year's finalist Madison Keys will face Naomi Osaka.

Sevastova and Osaka are both first-time Grand Slam semifinalists but still stand a chance at causing some huge upsets. Sevastova and Williams have never faced off before and that could prove tricky for the 23-time Grand Slam champion.

Keys will look to extend her career head-to-head record against Osaka to 3-0. They have faced off in New York before, in 2016, with Keys coming back to win in a dramatic third-set tiebreaker.
