Andy Murray's tactics on and against serve were key to his 6-4 6-4 6-4 victory over 14th seed Radek Stepanek. Here, commentator Jason Goodall explains with the help of Hawk-Eye how the Scot won.
Murray's tactics on the first serve were obvious - he was peppering the Stepanek forehand and that is the weakest of the Czech's shots.
But the Briton's tactics were different on his second serve.
He was targeting Stepanek's backhand - something the 14th seed failed to take advantage of.
He won just 50% of points on Murray's second serve.
It was obvious from Stepanek's graphics that he did not know where to serve to Murray.
That's because the Scot made 67% of returns when facing first serves and an outstanding 93% of second-serve returns.
The combination of top-notch serving and returning ensured wildcard Murray ran out the comfortable winner.
