US Open day two: Andy Murray’s loo-gate rocket, Emma Raducanu delight while Novak Djokovic has a fright

World No 1 Novak Djokovic’s bid for the Calendar Grand Slam is under way at the US Open, although not without a fright.

The 20-time major champion dropped the second set to 18-year-old qualifier Holger Rune, and only a nasty bout of cramp prevented the youngster inflicting more damage.

Ashleigh Barty also got off to a winning start against Vera Zvonareva in straight sets.

Meanwhile, Britain’s Emma Raducanu followed up her remarkable run to the last 16 at Wimbledon with another impressive display at a major to beat an opponent 13 years her senior.

Here, we look back at day two at the US Open.
