Jessica Pegula defeated Barbora Krejčíková 6–3, 6–3 in the US Open quarter-final on hard court, confirming her status as pre-match favourite with odds of 1.42 to Krejčíková's 3.12. Pegula's dominant performance saw her advance efficiently through the match without conceding a set, dismantling the Czech player's typically solid game across both sets. The American's decisive victory underscored her growing confidence on hard courts and her ability to neutralise one of tennis's most accomplished doubles and mixed-doubles specialists in singles competition.
