HALLE, Germany -- Roger Federer's bid for a ninth title at the Gerry Weber Open came to an end Saturday when he was beaten in the semifinals by Alexander Zverev, a rising German prospect who notched the biggest win of his young career.

Zverev's 7-6 (4), 5-7, 6-3 victory over the top-seeded, eight-time defending champion gave him a place in his first final of the year.

It also means that Federer, with 17 Grand Slam titles, still remains without a title this year, marred by knee surgery and a back injury that forced him to miss the French Open.
