The final scenes from Bath University were dramatic in the extreme, as Konta collapsed beside the court in the moments before her deciding set against Serbia’s Aleksandra Krunic, then recovered to see out her fourth singles victory in as many days.
Katie Boulter, Konta’s understudy, also returned a perfect record. Should Great Britain overcome Kazakhstan, whose second-string singles player is likely to be world No 96 Zarina Diyas, they would re-enter the World Group for the first time since 1993.
Confusingly, this is split into two parts at the moment, each containing eight teams. But the International Tennis Federation say that they are considering a rebrand of the whole event, in line with the recent Davis Cup charges. It follows that this would be an excellent moment to climb back among the world’s elite.
Meanwhile Naomi Osaka, champion of the two most recent grand slams, delivered the unexpected news that she has split with her coach Sascha Bajin.
On the face of things, this was a difficult decision to explain, especially as Osaka has climbed from No 68 in the world at the start of 2018 – the moment when she hired Bajin – to No 1 now.
Yet it is not unusual – particularly on the women’s tour – for players to change coaches at the height of their careers. Of the past five major champions, only one – Caroline Wozniacki, who has been coached by father Piotr since she took up the game – is still working with the same coach who helped them lift those titles.
