Dan Evans out-thought Bernard Tomic, according to coach Miles Maclagan
Maclagan spent three years as Andy Murray’s coach and tactical specialist and has worked with Brit Laura Robson as well.
He was watching on as Evans reached the fourth round of a Grand Slam for the first time, beating No 27 seed Tomic 7-5, 7-6, 7-6 in Melbourne.
And Maclagan believes the British No 3 had a clear plan to undo the Australian and exploit his weaknesses.

“That Tomic forehand can be vulnerable at times and Evans knew his slice was a key weapon,” Maclagan told Eurosport.
“He knows if he can keep the ball in the centre of the court and low, he’s not really going to be challenged by the Tomic forehand.
“He’s very comfortable rallying and mixing up the pace.

“His transition game has really improved as well so he’s looking for that short ball and it’s a really great play for him.
“He was also looking to expose Tomic’s movement out to that forehand side which is a bit slow.
“Because he’s looking for the short ball, he’s nicely up the court which takes away all Tomic’s time and he can rush him.”
Evans, who only recorded his first career win against a top 10 player last week against Dominic Thiem but has since also dispatch Marin Cilic, will now face Jo-Wilfried Tsonga.
The Frenchman beat Jack Sock in four sets to reach the last 16 but admitted he was far from his best.
Evans is currently ranked 39 places below the 31-year-old but will be playing the biggest match of his life with a quarter-final berth at stake.
