SHANGHAI, Oct. 12 (Xinhua) -- NO.16 seed Juan Martin del Potro of Argentina produced one of his best performances of the season here on Thursday, overcoming one-set defict to beat third-seeded Alexander Zverev of Germany 3-6, 7-6(5), 6-4 to reach the Shanghai Rolex Masters quarter-finals.
The 20-year-old Zverev, who has collected 5 ATP World Tour titles this season, lost his temper when broken by the Argentine at 2-2 in the decider and flung his racquet down to the ground.
"I think he played a great match, maybe one of the best of the season. I think we both played pretty well from the baseline...but for me, in my eyes it's impossible to lose a match where I get broken one time and I still lose it except if you play against Isner or Karlovic, someone like that.," Zverev said after the match.
Zverev came to the match strong and raced to a 3-0 lead in the first set within 10 minutes. But Del Potro found his form in the second set, scored 5 love games and levelled the set-score with a 7-5 victory in the tiebreak.
"I think I didn't play well the first game of the match with my serve, but when I saw the stats on the TV, and I was winning more points returning than him, but I lost the set. I say to me, Okay, you're playing good. You have to just try to keep going. And that's what I did for the second and the third set," the 2009 US Open champion Del Potro said.
Zverev, who has already secured a berth in the ATP World Tour Finals in London, fired 22 Aces in the match, but couldn't find solutions when his opponent served.
Del Potro, the 2013 Shanghai Masters runner-up, will face either American no. 12 seed John Isner or Viktor Troicki of Serbia on Friday.
