BERLIN, May 3 (Xinhua) -- Cristian Garin saved two match points before stunning two-time defending champion Alexander Zverev 6-4, 5-7, 7-5 in the quarterfinals of the Munich Open on Friday.

Garin, ranked 47th, claimed his first win over a top-10 player. The 22-year-old squandered three match points in the second set, fought back from a break down in the final set and saved two match points before winning in more than two hours on the outdoor clay.

The defeat means Zverev will drop to fourth, with Roger Federer taking his No. 3 position on Monday.

Garin next faces third-seeded Marco Cecchinato, who rallied to beat Marton Fucsovics of Hungary 1-6, 7-5, 7-5.

Matteo Berrettini defeated three-time champion Philipp Kohlschreiber 4-6, 7-5, 6-4 and will face fourth-seeded Roberto Bautista Agut, who also fought back to beat Guido Pella 4-6, 6-4, 6-0.
