Britain's Emma Raducanu suffered a disappointing defeat to world number 101 Cristina Bucsa of Spain in the opening round of the Singapore Open.
The 22-year-old was playing for the first time since her 6-1 6-0 third round loss to Iga Swiatek at the Australian Open and the news her coach Nick Cavaday was stepping back from the role to "prioritise getting back to full health".
But in a gruelling encounter lasting three hours and three minutes and featuring 17 breaks of service, Bucsa came through 5-7 7-5 7-5 against the seventh seed in the pair's first meeting.
