Eight seed Janko Tipsarevic has progressed to third round of Wimbledon following a hard-fought win over Ryan Sweeting.
The unseeded American took the opening set by converting his only break point of the entire match in game 12.
Tipsarevic was imperious on his serve thereafter and won 20 out of 20 points behind his first serve as he took the second set with a solitary break.
The third set was won in almost identical style, but the Serbian turned on the style in the fourth, showing his class with two ruthless breaks of serve to wrap up the 5-7 7-5 6-4 6-2 win in just under three hours on Court No. 2.
Mikhail Youzhny or Inigo Cervantes-Huegun await Tipsarevic in round three.
