Former British number one Heather Watson battles past Leylah Fernandez in Alcapulco to win her first WTA title since 2016 with a 6-4, 6-7(8), 6-1 victory.
Watson bullied her way through the first set with some aggressive tennis, earning an early double-break lead en route to a commanding 4-0 lead against the 17-year-old qualifier.
But the Brit failed to convert any of her five championship points in the second set tie-break as she went 6-2 up with Fernandez forcing her into unforced errors.
Watson regained her rhythm in the third as she kicked off with a double break but, again, she squandered four championship points at 5-1 up.
Nevertheless the 27-year-old Watson fought on and converted a forehand winner on her tenth match point to seal the title.
Following the contest which lasted two hours and 46 minutes, Watson is now projected to re-enter the top 50 of the WTA singles rankings - up from 69.
Watson??™s most recent title before this also came in Mexico at Monterrey in 2016.
"I'm so happy to get my fourth title," Watson said post-match.
" It??™s been a few years, so I??™m just really, really happy I came through that match."
She added: "I??™ve played Leylah two times before this, and I knew what to expect.
"She??™s a great player, and it would be really tough because the two matches before that had been really tough. The thing I notice about her the most is the head on her shoulders. She??™s very, very mature for her age.
"I think it??™s her mental toughness that really stands out," Watson continued. "I think she??™s going to have a great career ahead of her and rise up the rankings very quickly if she keeps playing like this."
