Nadal books Sock quarter-final

Rafael Nadal advanced to the quarter-finals of the Miami Open following a routine straight set win over Nicolas Mahut on Tuesday.

The Spaniard was simply too good for Mahut, taking never facing a breakpoint in his 6-4, 7-6(4) win on the hard courts of Miami.

Nadal put together a near perfect display, notching up 26 winners and just 11 unforced errors and was easily able to counter Mahut's serve and volley game plan.  

The opening set was a tight one, with neither earning a breakpoint until the ninth game, where an error gave Nadal an opportunity. Nadal did not need a second invitation and broke to go 5-4 up, after which he served out the set in dominant fashion.

The second set unfolded in a similar vein, with the duo swapping service games until the tiebreaker. But as per usual, Nadal was superb in the big moments and moved to a 5-2 lead before taking the set and the match.

Nadal will face rising star Jack Sock in the quarter-finals. The 24-year-old defeated Jared Donaldson 6-2, 6-1 earlier in the day to become the first American on the ATP Tour in 20 years to reach the quarter-final stage or better in four consecutive Masters 1000 events.
