South Korea's Inbee Park holds a one-shot lead at the halfway stage of the women's Olympic golf tournament after a day of low scoring in Rio de Janeiro.
The 28-year-old world No.8 carded a second consecutive 66 to reach ten-under-par and grab the slenderest of advantages over America's Stacy Lewis, who vaulted up the leaderboard and into second place courtesy of a 63.

Great Britain's Charley Hull is currently sitting in the bronze medal position alongside Brooke Henderson of Canada on eight-under. Hull's compatriot Catriona Matthew is in a tie for 11th on five-under-par.
Thirty-five of the 60 strong field broke par in the second round in Rio
First round leader Ariya Jutanugarn was unable to improve on her opening day's efforts, carding a level-par 71 to remain on six-under-par. The Thai's inability to break par was in stark contrast to the majority of the 60-strong field, 35 of whom did so. Indeed, Jutanugarn was the only player in the top 20 who failed to break 70.
Seven-time major winner Park, meanwhile, birdied three of her final four holes to leapfrog Lewis, pictured above, at the top of the leaderboard. Lewis' 63 was made all the more impressive by the fact that it included a bogey and a double-bogey.
Hull birdied her last three holes to complete an impressive day's work. She was joined on eight-under, just two behind Park, by 18-year-old Henderson, who birdied five of her last six holes en route to a flawless 64.
Inbee Park: Did you know...
Earlier this year, Inbee Park became eligible for the LPGA Hall of Fame after taking part in the KPMG Women's PGA Championship. At 27, as she was at the time, she was the youngest player ever to qualify for it.
