Emma Raducanu put in an impressive showing as she beat Beatriz Haddad Maia 6-1 2-6 6-4 in their third-round match at Indian Wells.
The British number one started strongly against the world number 13 and broke twice as she won the first set.
Raducanu dropped her serve twice as her Brazilian rival then levelled.
In the decider, Raducanu produced some brilliant tennis and broke Haddad Maia in the seventh game before keeping her nerve to serve out for the match.
Raducanu, who is 77 in the women’s rankings, will play world number one Iga Swiatek or Bianca Andreescu in the last 16.
