Iga Swiatek was relaxing in bed with her laptop when she heard the news: Ashleigh Barty, the recent dominant force in women's tennis and Australian Open champion seven weeks previously, was retiring.
A fortnight later, 20-year-old Swiatek has replaced Barty as world number one and marked the achievement in style by winning the Miami Open.
The triumph extended Swiatek's winning streak to 17 matches and was her third title in a row after also lifting WTA 1000 titles - the most important tournaments beneath the Grand Slams - in Doha and Indian Wells.
The first emotion for Swiatek, like everyone in the tennis world, was shock when Barty announced her decision to quit aged 25.
