Andy Murray overcame a shoulder niggle in his third round match on Saturday night to defeat Italian 25th seed Andreas Seppi in four sets, and ensure a place in the last-16 at the All England Club.

World number three, Murray, won 6-2, 6-2, 1-6, 6-1 and will now face Ivo Karlovic in fourth-round. The big-serving 36 year-old Croat, who is the oldest man to reach the last 16 since 1976, defeated Jo Wilfried - Tsonga 7-6, 4-6, 7-6, 7-6.

The Scot was two sets up and cruising, as he appeared in complete control in all area of his game until the 31 year - old Seppi took an injury break in the third set at 2-1 on serve, which shifted the momentum.

When the play resumed, Murray suddenly collapsed; his concentration lapsed, he became unsettled and lost the next four games and was broken in the first game of the fourth set. At this point the 2013 champion failed to win a game for a 40 minute period; the Scot was clutching his right shoulder and eventually asked for treatment in a medical time-out in the fourth set.

However, after losing six games in a row, Murray swept through the last six games of the match to wrap up the win in style, 6-1. He was enthusiastically supported by a Centre Court crowd.

British number one will now face Karlovic's dangerous serve on Centre Court today; the 23rd seed has hit astonishing 136 aces in his three victories so far, including 41 during his match against Tsonga.

Murray will need to be on his best returning game today to stay in the tournament; he is now Britain's last remaining player, as his fellow Brit James Ward failed to reach the last 16. Ward, who was in the third round of a Grand Slam for the first time, lost in five sets 6-4, 3-6, 2-6, 6-3, 8-6 against another big server, the Canadian Vasek Pospisil.

The other British Tennis star that exited from the All England Club in style, is Heather Watson; many will remember her heroic match against Serena Williams from last Friday, when the 23 year-old player almost knocked out her 33 year -old American opponent. But, Williams, who is five times Wimbledon champion snatched the victory after emotional three sets - Serena is playing her sister Vinus today!
