Katie Boulter's promising start was short-lived as she fell to American Ashlyn Krueger 3-6, 6-2, 6-2 in the Mubadala DC Open's first round. Meanwhile, Cameron Norrie ended his six-match losing streak on the ATP Tour with a 6-4, 6-1 win over Aleksandar Kovacevic in the Mifel Tennis Open. Boulter dominated the first set, breaking Krueger twice, but the American turned the tables in the second set, breaking Boulter twice to level the match. Krueger's strong finish saw her break Boulter three times in the final set to secure the win.

She will now face four-time Grand Slam champion Naomi Osaka in the second round. Norrie's victory over Kovacevic was not without its challenges, as he lost serve in the opening game and struggled to hold serve. However, he regained his composure to take the first set and then dominated the second, setting up a second-round tie against either Aidan Mayo or Jamie Duckworth.
