British number two Heather Watson is through to the second round of the Monterrey Open in Mexico thanks to a three-set win over Japan's Misaki Doi.
Watson, 23, who has fallen to 84th in the world after a poor start to the year, came through 6-4 6-7 (0-7) 6-3 against the world number 54.
The 23-year-old, who lost in the first round of the Australian Open, had been 2-0 down in the deciding set.
But she broke Doi twice to advance after two hours and 47 minutes.
Watson faces either Hungarian eighth seed Timea Babos or Polona Hercog of Slovenia in round two.
British number one Johanna Konta is seeded fourth for the tournament and faces Colombia's Mariana Duque-Marino in the opening round.
