Stanislas Wawrinka has reached the fourth round at Wimbledon with a comfortable straight-sets win over Denis Istomin.
The Swiss fifth seed broke twice late on in the first set to claim it 6-3 before tightening his grip with another 6-3 triumph in the second.
The Australian Open champion then opened up a 2-0 lead at the start of the third, and he was able to hold on to serve out the contest 6-3 6-3 6-4.
Waiting for Wawrinka in round four will be either American ninth seed John Isner or Spanish 19th seed Feliciano Lopez.
