Is this the break-out event for Jack in the bean Sock??? Very impressive win vs Raonic and backed up by a straight-set takedown of am aging but still talented former top-5 Blake! All of a sudden he's a QFist with a shot at listless Lopez and a winnable possible semi vs the Istomin/Russell winner. He has a junior slam title and a senior MD slam crown. As an American, I've been hoping one of our young guys could step up. This is the first glimmer of a result that shows someone is headed upwards. Keep it going, Jack!
