Zagreb: Jurgen Melzer of Austria upset fifth-seeded Italian Andreas Seppi 6-2, 6-3 on Wednesday to advance to the quarterfinals of Zagreb Indoors tournament.
Melzer was a late entry and had to play in qualifiers, but has lost just nine games in his first two matches. Melzer - a 2010 semifinalist - served nine aces against Seppi and converted four of his seven break points.
"I am very happy with the way I played so far," he said. "I needed some matches after an early exit in Melbourne, where I lost in the first round. ... And after many injury problems I had last year now I finally play pain free."
