Coco Gauff survived a serving nightmare and rallied from a set down to outlast Elise Mertens 2-6, 7-6(9), 6-3 in the Dubai quarterfinals on Tuesday. Despite hitting 16 double faults and landing just 45% of first serves, the American found a way to prevail in a match where Mertens actually won more total points (101-95) but couldn’t close out her opportunities.
The pivotal moment came in the second-set tiebreak, where Gauff saved multiple set points before edging ahead 11-9 after a grueling 80-minute set. That breakthrough shifted the momentum decisively, as Mertens’ aggressive game began to unravel in the decider. Gauff’s superior first-serve winning percentage (74% to 57%) proved crucial whenever she could land the ball in play, compensating for her disastrous second serve that won just 33% of points.
Gauff closed out the match by converting her sixth break point opportunity of the final set, sealing her advancement after two hours and 43 minutes of fluctuating fortunes on the Dubai hard courts.
Key Takeaways
- Gauff’s 16 double faults nearly cost her the match, more than doubling Mertens’ six. Her first-serve percentage of just 45% put constant pressure on her second serve, which won a woeful 33% of points.
- The American’s ability to dominate on her rare successful first serves (74% points won vs Mertens’ 57%) kept her competitive despite serving poorly overall. When she found the box, she was formidable.
- Mertens won more total points (101-95) but crucially lost the only set that went to a tiebreak, squandering 11-9 in a second-set breaker that lasted through multiple set points and shifted the match’s momentum irrevocably.
- Break point conversion told the story: Gauff converted 6 of 10 opportunities (60%) while Mertens managed only 7 of 13 (54%). In a match this tight, that five-percentage-point edge made the difference.
Player Analysis
Coco Gauff
Gauff’s performance was a study in perseverance over precision. Her serve, typically a reliable weapon, betrayed her spectacularly — 16 double faults and a 45% first-serve percentage would sink most players. Yet she compensated with exceptional returning and clutch play when it mattered most. Her 74% success rate on first serves showed what she’s capable of when the mechanics align, but her 33% on second serves exposed a vulnerability Mertens exploited throughout but couldn’t quite capitalize on in the key moments.
What separated Gauff was her mental resilience in the second-set tiebreak and her ability to raise her break point conversion rate (60%) when facing elimination. After the disastrous first set, she adjusted tactically, became more aggressive on returns, and forced Mertens into making the errors down the stretch.
Elise Mertens
Mertens played the cleaner match statistically — serving better (67% first serves to Gauff’s 45%), hitting more aces (3-1), and actually winning more total points (101-95). Her controlled aggression dominated the opening set and nearly carried her through in two. But tennis rewards conversion in critical moments, not cumulative excellence, and Mertens faltered precisely when the match hung in the balance.
The Belgian’s 7-for-13 break point conversion (54%) wasn’t poor, but against a struggling server, she needed to be more clinical. Her 57% success rate on first-serve points was solid but not dominant enough to compensate for letting the second-set tiebreak slip away. Once Gauff seized momentum in the decider, Mertens couldn’t rediscover the rhythm that had carried her through the first 80 minutes.
