Heather Watson reached the BNP Paribas Open second round at Indian Wells with a nervy win over German Julia Goerges.
Watson won the first set and served for the match at 5-3 in the second but lost five games in a row as Georges took the second set and led the decider.
But the British number one rallied to win 6-4 5-7 6-3 and book a second-round meeting with 29th seed Camila Giorgi.
"I was definitely a bit nervous and it showed," said Watson, 22. "But I found the right way to finish the match."

|"Seven weeks without a main draw win hardly constitutes a crisis - especially when you have just won a WTA tour title - but this was a very important win for Watson. Her nerves became apparent when she served for a straight sets win at 5-3 in the second, so full credit to her for coming through in the decider having lost four games in a row."|
It was only the British number one's second victory since taking the title in Hobart at the start of the year.
British men's number two James Ward will not compete in the main draw at Indian Wells after losing in the final round of qualifying.
The world number 108 went down 6-3 6-1 to Germany's Mischa Zverev.
