Video - Overwhelmed in the rally, Sinner pulls off a fabulous lob against Marozsan in Beijing

Jannik Sinner is truly unstoppable. Facing Fabian Marozsan in the quarterfinals of the ATP 500 in Beijing, the Italian once again proved extremely solid... delivering shots that came out of nowhere.

Troubled in the second set by an aggressive Hungarian, the world number two executed an exceptional lob to level the score at 30-all (the score was 6-1, 3-3).

The battle didn't stop there for the four-time Grand Slam winner as he had to recover from a break down in the second set.

While serving to level the match at one set all, Marozsan failed to maintain momentum: conceding 12 of the next 13 points played.
