Prior to the contest, indications heavily favored an easy triumph for Swiatek.
In her preceding three Grand Slam encounters, she had conceded a mere five games – highlighted by a 6-0 6-0 rout of Amanda Anisimova in the Wimbledon final of July – and had secured 14 consecutive sets at major tournaments.
Conversely, US Open first-timer Lamens had never progressed past the second stage of any Grand Slam event.
This disparity was quickly apparent, as Lamens failed to register a single clean winner in the initial set.
However, Swiatek, the victor at the Cincinnati Open leading up to Flushing Meadows, lost her momentum during the second set.
The six-time Grand Slam titlist and her support staff visibly expressed annoyance at several errant shots from the baseline, ultimately resulting in a match tally of 29 uncoerced mistakes.
Nevertheless, Swiatek re-established a degree of composure in the final set and minimized the impact of surrendering a service break to arrange a showdown with Kalinskaya.
