Wimbledon 2013 tennis tournament continues on Thursday with an action packed Day 4 scheduled. All the action can be watched online for free through live streaming, and will show matches today involving Serena Williams, Novak Djokovic and Britain's Laura Robson.

Tennis fans will have to catch their breath after a day of drama on Day 3 on Wednesday. Seven time Wimbledon champion Roger Federer was unceremoniously knocked out in a huge shock in his second round tie. It was his earliest Wimbledon exit since 2002, and came against World Number 116 Sergiy Stakhovsky.

Federer lost 6-7 (5-7) 7-6 (7-5) 7-5 7-6 (7-5) on a day where a record seven other players retired through injury.

In addition, Jo-Wilfried Tsonga also exited the competition – joining Rafael Nadal, who lost in round 1, boosting Britain's Andy Murray's chances at moving through the rounds towards an expected final with Djokovic.

On his defeat Federer said, "You don't panic at this point, that's clear. It's normal that after all of a sudden losing early, having being in Grand Slam quarter-finals 36 [straight] times, people feel it's different. But I still have plans to play for many more years to come."

"When you play Federer at Wimbledon it's like you're playing two people," said Stakhovsky, "Federer and his ego. I hoped he wouldn't get too far away from me and I hung in there every game on my serve, trying to play for a tie-break. It was magic, I couldn't play any better today. Every important point I played well and I served and volleyed incredibly well."

On Thursday Djokovic will play America's Reynolds, and they will be third on Center Court. On No. 1 Court, Serena Williams will be first on against Garcia of France. She will be followed by matches involving Gasquet, and also Ferrer.

Meanwhile, for the thousands of British supporters, Laura Robson will be sure to rally fans – she is fourth on No. 2 Court, and will be playing Duque-Marino.
