Carla Suarez Navarro recovered from losing the first set to secure the biggest title of her career with a 1-6 6-4 6-4 victory over Jelena Ostapenko in the Qatar Total Open final.
Ostapenko, who won the only previous encounter between the pair at Wimbledon last year, started strongly as she produced eight forehand winners on her way to claiming the opening set.
But Suarez Navarro was playing her 10th career final and she used her experience to haul herself back into the match as she took advantage of 30 errors on the backhand from the Latvian to close out victory.
Suarez Navarro said in her on-court interview: "I started a little bit nervous and she started really good. It's not easy to play like this, and I lost the first set but I believed, I fought, I ran, and finally I won."
The Spaniard will climb to number six in the world and added: "It's amazing, a dream come true. I was in the top 10 last year but not number six, so it's a special number.
"This tournament was really tough. The best players in the world were here, and it's so special. You have to play every day, and it's not easy.
"But these wins give me a lot of confidence, the experience that I take from this. I've lost a lot of finals, so I'm really happy and excited about this tournament."
