Leading British junior Katie Swan has bowed out of the US Open after struggling with the hot conditions during her first-round contest with Tessah Andrianjafitrimo.
The 16-year-old, who reached the Australian Open final at the start of 2015, had been handed a tough draw against Andrianjafitrimo and had dropped the first set on a tie-break.
Swan immediately fell a break behind at the start of the second before the doctor was called onto Court 6 to assess her condition.
After a 10-minute break, she was allowed to continue, but a game later, the decision was made for Swan to withdraw from the match before she was helped off court with heat exhaustion.
