Teenager Molleker claims maiden Tour win in Stuttgart stunner

Seventeen-year-old Rudolf Molleker will face Lucas Pouille in the second round in Stuttgart after claiming his first tour-level win.

Rudolf Molleker claimed his first ATP Tour win on Monday as he stunned Jan-Lennard Struff at the Stuttgart Open. The 17-year-old sent down 26 aces to defeat his German compatriot 6-4, 6-7 (5-7), 6-3 in only his second tour-level main draw match.

Molleker, who will now face Lucas Pouille in the second round, said: "It's an unbelievable feeling to earn my first main draw win on home soil. It felt great to have the crowd have my back and I just enjoyed the centre court feeling. It's a great experience for me and hopefully I can go on."
