in the second round to Muguruza in a marathon three set match that had the latest start in Australian Open history and ended after 3am local time. Konta's next played the Fed Cup. Britain's ties in Europe/Africa Group 1 took place in Bath after the LTA were awarded co-hosting rights. This was the first time that the British Fed Cup team had played on home soil in 26 years. Konta recorded wins over Dalila Jakupović, Maria Sakkari and Anna Bondár as Britain topped their opening round pool with a 100% record to set up a promotional play-off with Serbia. Following a victory for teammate Katie Boulter in the opening rubber, Konta beat Aleksandra Krunić in a dramatic match to seal Britain's progress to a World Group play-off despite collapsing off-court after the end of the second set and requiring a medical timeout. Konta won a Fed Cup Heart Award for her efforts. Konta opted not to play in either Doha or Dubai, instead returning to WTA action for the North American spring hardcourt swing. Her first event was in Acapulco where she defeated Laura Siegemund in the first round, followed by victory over Varvara Flink before losing in the quarterfinals to Donna Vekić. At Indian Wells, she defeated Pauline Parmentier and 27th seed Hsieh Su-wei, but went out to Kiki Bertens in the third round. In Miami, she lost in the second round to Wang Qiang of China. Konta returned to Europe to rejoin Britain's Fed Cup team for their World Group II play-off against Kazakhstan. This was played at the Copper Box Arena in London. It was the first time the venue had hosted international team Tennis. In the play-off Konta twice recovered from a set down to beat Zarina Diyas and Yulia Putintseva. Konta's two victories took her winning run in Fed Cup singles play up to 11 matches. Teammate Boulter completed Britain's victory by three rubbers to one as she beat Diyas. Britain were therefore promoted to World Group II for 2020. After returning from Fed Cup duties Konta entered the Morocco Open as the seventh seed. She saved three match points during her first round match against Wang Yafan before rallying to outlast the Chinese player in three sets and progress to a second round encounter with Ana Bogdan. She beat Bogdan and followed that by ousting Hsieh, the tournament's second seed, to reach the semifinals.
