In tennis, defending Champion Novak Djokovic has advanced to the 3rd round of the US Open after defeating the Argentine Juan Ignacio Londero in straight sets.

The World Number 1 who's looking for his 3rd grand slam crown of the season at Flushing Meadows, dominated the match in the opening set and finished it 6-4. Londero gained considerable strength in the 2nd set, but the Serbian Ace used his experience and ended it 7-6 in his favour.

The 16-time grand slam winner regrouped in the 3rd and easily finished the 3rd set 6-1 to wrap up the match in 2 hours and 12 minutes. Djokovic also notched his 71st victory at the season's final Grand Slam, tying his former idol and 5-time champion Pete Sampras at the US Open. He will next meet the winner between American Denis Kudla and compatriot Dusan Lajovic.

Meanwhile, 20-time Grand Slam champion Roger Federer came from a set down to defeat Bosnian Damir Jumhur and advance to the 3rd Round. After falling 4-nil behind, the Swiss Maestro conceded the 1st set 3-6 to the world number 99. This was Federer’s 2nd consecutive sluggish start, having also dropped the 1st set against Indian qualifier Sumit Nagal in his opener.

However, the World number 3 rose to the occasion once more on Wednesday and rallied to claim the next 3 sets 6-2, 6-3 and 6-4. Next in Federer's path is the winner of a later match between French 25th seed Lucas Pouille and Britain's 58th-ranked Dan Evans. 5-time US Open winner who lost to Novak Djokovic in last month's epic 5-set Wimbledon final, hasn't fallen in a Slam 2nd Round since 2013 at Wimbledon.

Finally, 2014 US Open runner-up Kei Nishikori continued his bid for a 1st Grand Slam title after fending off Bradley Klahn of the US 6-2, 4-6, 6-3 and 7-5 on Wednesday. World Number 6 who needed 5 match points to seal the win, will next meet either Australian Alex de Minaur or Chilean Cristian Garin.
