As unlikely as Bianca Andreescu's wild card victory in Indian Wells was on Sunday, she has actually been specialising in upset wins for years. When only 12 years old for instance, Andreescu's confident father Nicu challenged his daughter to a match while on a family holiday in Florida and bet her $50 (£38) on the outcome.

The result? "I creamed him," Andreescu revealed in a recent interview.

Anyone who saw Andreescu, a precociously talented 5ft 7in 18-year-old from Canada, in Indian Wells over the last couple of weeks will recognise that fearlessness and conviction. Having ended last year ranked No. 178, Andreescu was awarded a wild card into Indian Wells - tennis's most respected event outside the grand slams - on the back of an excellent start to 2019 that began in Auckland with back-to-back wins over Caroline Wozniacki and Venus Williams.

Buoyed by her recent improvement, Andreescu surged to the Indian Wells title with a three-set win over former Wimbledon champion Angelique Kerber in Sunday's final. Along the way she also took out the world No. 6 Elina Svitolina and destroyed two-time major winner Garbine Muguruza by a barely credible 6-0, 6-1 scoreline. Canada's Prime Minister Justin Trudeau was so impressed by Andreescu becoming Indian Wells' first ever wild card winner that he tweeted on Sunday: "From a wild card to the Indian Wells champion – Bianca Andreescu just made history."
