I can't turn on the volume right now, what's del Potro arguing about?
Huh? Why did he get that?
He didn't argue about a point penalty. He claimed that Jarkko's first serve was a let (he missed the return and the machine didn't go off).
After Nadal beat Monfils at Doha, before AO 2014
lol, who will beat him? Wawrinka? Berdych? Gulbis? Rosol? Federer?
Only Del Potro can take him out before the semis, and he won't. Nadal is winning the AO, bet your house on it.
Somewhere out there, there is a homeless person who once took betting advice from GSMnadal
