American Jack Sock crashed out of the French Open after a fiery outburst at a chair umpire, during his second round defeat to Dominic Thiem.

Sock went out in straight sets against the No.3 seed as Thiem booked his place in the third round with a 6-1 6-3 7-6 (10-8) win.

The American qualifier showed his ugly side in an angry exchange with chair umpire Aurelie Tourte after a call went against him in the third set.

The 28-year-old qualifier was already two sets to love down at the time and his mood only worsened when his serve was called long by the chair umpire.

Sock was unconvinced by the call from the umpire, who insisted that the ball hadn't touched any part of the line.

However, he was less than impressed when the umpire explained that she couldn't actually identify the mark from the ball on the clay.

The umpire tried in vain to convince Sock that while part of the mark was visible, she had to "draw" the remainder of the mark in her head.

The American then went on to argue that the marks regularly differed in size, before sarcastically referring to the umpire as a "superhero".

Sock said her explanation made "zero sense" before accusing the official of making up facts to suit her case.

"You're literally guessing. That's what you're saying," Sock fumed.

Nadal and Thiem on Paris collision course

Thiem survived a third-set wobble in the victory over Sock and remains on a collision course with World No.2 Rafael Nadal.

The Austrian world No.3 needed just 25 minutes to break Sock, a former top 10 player, three times and storm through the first set.

Thiem was brimming with confidence on his favourite surface after winning his first grand slam title earlier this month.

Thiem will next play Casper Ruud, a semi-finalist in Rome this month, after the in-form Norwegian downed American Tommy Paul in five sets.

Nadal's quest for a record-extending 13th French Open title continued with a 6-1 6-0 6-3 crushing of American Mackenzie McDonald in the second round.

The Spanish second seed, also looking to equal Roger Federer's record of 20 men's singles grand slam titles, next faces Stefano Travaglia after the Italian beat Japan's Kei Nishikori in five sets.
