Jack Sock hit a tweener lob winner in Shanghai

There are few things in tennis more exciting than a tweener. Watching someone return a ball through their legs never gets old. But you know what is more exciting? A tweener winner. And even better than that? A tweener winner lob.

Allow Jack Sock, my friends, to show you how it's done.

Sock's impressive feat occured during the quarterfinals of the Shanghai Rolex Masters on Friday. Unfortunately, it wasn't enough for the American to beat Frances' Gilles Simon, who was at one point down a set and a break and managed to come back for a win.
