"This is how close we are to the action, I just got told to shut up by Gulbis! Quiet he said!"- Commentator
Regarding the line call: according to the commentator he could have challenge that
but yea, it doesn't look like a challenge active court. Shame!
Edit: NOW the commentator confirmed there was no challenge system. Earlier they said "Pointing to the mark but decided not to challenge" Way to get with the game guys!
