• Konta battles fatigue to seal 2-0 victory over Serbia
• Katie Boulter earlier won her rubber in straight sets
Johanna Konta has already achieved many things in her career, including being within one win of a Wimbledon final, but in terms of sheer effort, there have surely been none finer or more courageous than this.
Physically exhausted and mentally spent, the Briton somehow managed to haul her body over the line and with it, secured her country a chance to reach the elite World Group of the Fed Cup. Britain’s 2-0 win over Serbia in Bath means they will now compete in a World Group II play-off in April for a chance to return to the second tier of the sport’s flagship women’s team competition for the first time since 1993.
