During the final set of the match, Raducanu's concentration was broken by a crying infant in the stands, leading her to vocalise her annoyance to the chair umpire.
The umpire responded by asking if Raducanu wanted the child removed, prompting cheers from the crowd.
The long and tireless match lasted over three hours, with Sabalenka ultimately clinching the win 7-6(3), 4-6, 7-6(5).
Raducanu is next scheduled to play in the 2025 U.S. Open, participating in the main draw of the women's singles.
