8. Jacob Fearnley (210)
Fearnley didn’t compete at the highest level consistently this year, though he’s produced some memorable moments in his young career. A powerful server who honed his game on the American college circuit, Fearnley approaches his service games with notable freedom. That looseness comes at a cost: he averages 5 double faults per match, second only to Shapovalov on this list.
9. Jakub Mensik (199)
Mensik’s inclusion makes sense when you consider his serving prowess. He’s such a strong server that he probably believes he can hit an ace even with his second delivery. Naturally, he attempts it often, and just as naturally, it doesn’t always work. His 3.8 double faults per match is manageable overall, especially given the rewards his aggressive approach generates.
10. Reilly Opelka (198)
No proper list of double fault leaders would be complete without Reilly Opelka. As one of the tour’s premier servebots, he launches aces with regularity but inevitably produces double faults as well. His 198 total in 2025 translates to 3.73 per match, a figure easily offset by the sixteen aces he averages. For Opelka, it’s simply the cost of doing business.
