Though many entertaining matches last several hours, points and sets, there is no doubt that some straight-set matches can provide just as much viewing enjoyment.
Recently there has been an increasing amount of lengthy, tough matches played across all surfaces.
Many matches of the past few years have been historic (examples are the longest Davis Cup match of all time and John Isner's unprecedented lengthiest match in history against Nicolas Mahut).
But even when there is a loser (sometimes in straight sets), he still tries his best to show what he is made of.
These entertaining straight-set matches date back since 2012 and are ranked in order of quality of points, stage and caliber of the tournament and overall drama surrounding the match.
