California: Teenager Mirra Andreeva underlined her growing reputation as the hottest emerging talent on the WTA Tour by shocking world number one Aryna Sabalenka to win the Indian Wells title.
Russia's Andreeva, 17, produced a composed and clinical performance to fight back for a 2-6 6-4 6-3 victory.
It is her second successive title - and back-to-back victories at WTA 1,000 level - after triumphing in Dubai at the end of February.
Speaking to the Indian Wells crowd during the trophy presentation, a laughing Andreeva said: "I'd like to thank myself - for fighting until the end, for always believing and for never quitting, the BBC reported.
"I tried to run like a rabbit because Aryna was sending bullets across the net and it was hard."
Andreeva is the youngest champion in WTA history at this level - the highest tier of events below the four Grand Slam tournaments - and extended her winning streak to 12 matches by beating Belarusian three-time major champion Sabalenka.
On Monday, Andreeva will rise to a career high of sixth in the world rankings.
Andreeva has been tipped as a potential superstar ever since bursting on the scene as a
15-year-old at the 2023 Madrid Open.
Former British number one Andy Murray was impressed enough to text a good luck message on her Grand Slam debut at the following year's French Open, while several former major champions, including Andy Roddick and Martina Navratilova, have been among many predicting she will be a future world number one.
"Andreeva is playing well above her years," said Navratilova, who was analysing the final for Sky Sports on Sunday.
