Kecmanovic Pushes the Champion to the Limit
From the very beginning, Miomir Kecmanovic refused to be intimidated by Centre Court or by the defending champion.
The Serbian broke Sinner late in the opening set to claim it 6-4 before the Italian responded strongly in the second.
Just when momentum appeared to shift completely toward Sinner, Kecmanovic produced some fearless tennis to edge an incredible third-set tiebreak 8-6, moving within one set of one of the biggest victories of his career.
Sinner Responds Like a Champion
Champions often reveal their greatness when facing adversity.
Sinner did exactly that.
Rather than allowing frustration to affect his game, he raised his intensity considerably during the fourth set.
His powerful baseline hitting, improved serving, and aggressive returning left Kecmanovic struggling to maintain the same level.
Sinner dominated the fourth set 6-2 before carrying the momentum into the deciding fifth set, where he secured the decisive break and closed out the match 6-3.
Injury Scare During the Match
One worrying moment came when Sinner slipped during play and later appeared with blood visible around his shoe.
Medical attention was briefly required, raising concerns among fans watching Centre Court.
Fortunately, after the match Sinner indicated the injury was only minor and confirmed he expects to continue without major issues.
Turning Point of the Match
The defining moment arrived after Kecmanovic captured the third-set tiebreak.
Many expected the Serbian to complete the upset.
Instead, Sinner completely changed the tempo of the contest.
His first-serve percentage improved significantly while his forehand became increasingly dominant.
The defending champion also reduced his unforced errors, allowing him to dictate rallies throughout the final two sets.
