Elmer Moller will have a major opportunity on Friday at the Mutua Madrid Open, where he is set to face World No. 1 Jannik Sinner in the third round.
After earning back-to-back ATP Tour wins for the first time in his career, the 22-year-old Dane now gets the chance to measure himself against Sinner, who arrives on an 18-match winning streak. ATPTour.com breaks down five things to know about Moller.
Madrid comes full circle
The ATP Masters 1000 event in Madrid holds special meaning for Moller. It was here that he qualified for his ATP Tour debut last year. Although he lost his opening match to then-18-year-old Brazilian Joao Fonseca, the Dane has since grown more comfortable in the high-altitude conditions of the Spanish capital. After returning for the 2026 tournament, he has already collected four wins, including two in qualifying.
Backhand brilliance
Moller faces a tough challenge against Sinner, one of the cleanest ball-strikers on Tour, but he brings a major weapon of his own: his two-handed backhand. Smooth and explosive, it has underpinned his rise in recent years. In his first-round win over Federico Cina in Madrid, Moller fired 29 winners, 14 of them off that wing.
ATP Challenger success
Moller has enjoyed a string of strong results at ATP Challenger level, claiming four titles so far — and three of them in an impressive 2025 season. All four titles came on clay and in Oeiras last year, he defeated three Top 100 players (Thiago Monteiro, Roman Safiullin, and Francisco Comesana) while dropping just one set en route to the trophy.
Chasing the Top 100
Thanks to his Challenger success in 2025, Moller climbed to a career-high No. 102 in the PIF ATP Rankings in July. With his run so far in Madrid this week, he has risen 18 places to No. 141 in the Live Rankings, and he will aim to keep building momentum toward a Top 100 breakthrough — regardless of the outcome of his first Lexus ATP Head2Head clash with Sinner.
Danish roots
Raised in Aarhus, Denmark, Moller developed his game locally before beginning to travel internationally at age 11. His father, Jesper Bak, has played a key role in his journey. Moller is looking to establish himself among Denmark’s top players, following in the footsteps of the likes of former World No. 4 Holger Rune.
