Roger Federer had a blast playing with Jack Sock in the Match for Africa last night. But Sock? Well, he got a little fed up with the Swiss maestro toying with him. Watch as he gets foiled again by the Fed and elects to jump the net and take matters into his own hands--first time we've ever seen that.

Federer is known for his footwork but the 20-time major champion but his knees in the mix during the Match for Africa on Monday night in San Jose. Federer drops to his knees mid-way through this point and somehow, ends up winning it. Honestly, Sock helped Federer out on this point, but full marks to Federer who did some amazing racquet work and finished the point with an over the shoulder shot that was just pure maestro.
