Andy Murray has booked his place in the third round of the Cincinnati Open with a straight-sets win over Joao Sousa.
The eighth seed will now face either John Isner or Marinko Matosevic for a spot in the quarter-finals.
Murray broke early in an opening set that saw him hit 11 winners, though he had to save a break point on his way to closing it out 6-3.
The Brit then opened up a 3-1 lead in the second, and he was able to seal his progress by breaking the Portuguese world number 37 again at 5-3.
