No. 4 seed Andy Murray of Great Britain continued his dominance over No. 13 seed Gilles Simon with a 6-3, 6-4 triumph to advance to the quarterfinals.  
 
It was Murray’s ninth consecutive win over Simon and fifth time that he had defeated him in straight sets.

"He's one of those guys that almost feels sometimes the better you play against him, the better he plays," believes Murray. "Sometimes you need to put in a bit of junk really to make him make mistakes and change the pattern of the points. Because when you're just hitting, hitting, hitting, he hardly ever misses. He's a very tough guy to play against."

The six-foot-three, 185 pound Brit stayed in command throughout by winning on 73 percent of his serves and nullified any chance of a comeback by saving break point on all three occasions.
 
Murray was actually more efficient on his second serve (79 percent) than his first serve (69 percent). 

Murray, who notched his 22nd career ATP Tour title earlier this year in Brisbane (d. Dolgopolov), improved to 16-3 this year. 

He’ll meet No. 9 seed Janko Tipsarevic of Serbia next.  Murray leads the all-time series 4-3.
In their most recent match, Murray slipped past Tipsarevic 6-4, 7-6 on Murray’s home soil at the AEGON championships in London last June.
    
Tipsarevic ousted the only unseeded player remaining in the men’s singles draw by topping Grigor Dimitrov 7-6 (3), 6-2, in a fourth round match. Break point opportunities were scarce as each player held a distinct advantage on their serve.

Tipsarevic won on 85 percent of all his serves while Dimitrov won on his first serve at an 83 percent rate. But Tipsarevic was able to take advantage of Dimitrov’s much more conservative second serve.  The 20-year-old Bulgarian won just eight points on his second serve and Tipsarevic did not face a break point.

Tipsarevic improved to 3-0 in head-to-head meetings and will now face the winner of No. 13 seed Gilles Simon of France and No. 4 seed Andy Murray of Great Britain in a quarterfinal.
 
Dimitrov, who entered ranked No. 101, is assured to climb inside the Top 100 with his impressive run in Miami. He won three matches including a pair against seeded players by beating No. 7 seed Tomas Berdych and No. 29 Juan Ignacio Chela.
