Dimitrov pulls off two incredible trick shots

Australia's Bernard Tomic will face defending champion Grigor Dimitrov of Bulgaria in the semi finals of the Stockholm Open.

And if the above video is anything to go by, Tomic will certainly have his work cut out for him.

Dimitrov pulled off two ridiculous shots on consecutive points against American Jack Sock before overcoming the teenager.

The Bulgarian was severely outplayed in both points before hitting a winner behind his back, then hitting one in between his legs on the very next point.

His opponent Sock couldn't do anything but applaud Dimitrov's brilliance.

Tomic recovered from a miserable start to beat Fernando Verdasco of Spain 0-6, 6-4, 7-6 (6).

Tomic said that "to be able to come back and win the second set after losing first with six-love is very hard and I'm very pleased."

Dimitrov also lost the first set before beating Sock 5-7, 6-4, 6-3.

Top-seeded Tomas Berdych beat Marius Copil of Romania 6-2, 6-2 to also reach the semi finals.

The Czech, the 2012 Stockholm champion, needs to win his next match against German qualifier Matthias Bachinger to stay in the running for a berth in the eight-man ATP finals.

Bachinger served 13 aces as he defeated Frenchman Adrian Mannarino 4-6, 6-1, 6-4.
