Australian Bernard Tomic's poor form has continued, as he was obliterated by No.6 seed, Dominic Thiem, in the opening round of the French Open overnight.

Thiem dispatched the Aussie 6-4, 6-0, 6-2 in just over an hour.

Tomic said his Austrian opponent, who is one of the favourites for the title, was simply far too good.

“I was playing top two, three player on clay, and he's been playing well, and really no chance today," Tomic said post-match.

“He killed me from the start, from the 2-all game, and that's why he's been playing so well.

“He's a huge favorite to do well in this Roland Garros this year.

“At the clay level I'm not quite there near him at this moment but hopefully one day in a few years I can improve on this surface and there's been positive signs this year.”

Tomic put up some resistance in the first set, however, struggled to maintain the aggression thereafter.

The 24-year-old lost the second set in just 16 minutes and the third in just 22.

Thiem will now face either Simone Bolelli or Nicolas Mahut in the second round.
