Giraldo loses it after controversial net call

Santiago Giraldo endured a rough day at the Sydney International as he lost from a set up against Spanish eighth-seed Marcel Granollers.

After losing in the second qualifying round but making his way to the main draw as a lucky loser, the Colombian was always up against it on Tuesday.

But when the 29-year-old took out the first set in a tiebreak his confidence was up.

With the second set on serve in the sixth game, however, Giraldo was deemed to have touched the net.

"What can I do? The point is in play, you touch the singles stick, you lose the point," the umpire told Giraldo.

Soon after, Giraldo was serving to save two break and set points but hit the ball into the net to level the match up for Granollers.

Granollers would go on to win 6-7 7-5 6-3, setting up a clash with British player Daniel Evans.

At least Giraldo was able to control his aggression, unlike Coco 'loco' Vandeweghe.
