Former French Open champion Jelena Ostapenko capped a sudden return to form by winning the Luxembourg Open.
The Latvian has endured a largely-miserable season and had slumped outside the top 70 in the world but linking up with Marion Bartoli in a coaching capacity appears to have inspired her.
After reaching the final in Linz last week, Ostapenko went one better, beating defending champion Julia Goerges 6-4 6-1 to win her first title for more than two years.
Ostapenko said on wtatennis.com: "Of course it's great to finish the season with winning a title, especially in the last tournament. I enjoyed this week so much, and I think I played really well today."
At the Kremlin Cup in Moscow, Belinda Bencic finished off a week that saw her qualify for the WTA Finals for the first time by winning the title.
The Swiss had needed to reach the final to book her spot in Shenzhen, and ensured she would be heading to China with silverware after beating Anastasia Pavlyuchenkova 3-6 6-1 6-1.
Bencic said: "I had no pressure going into this match. We were so happy yesterday, celebrating, and this is the cherry on top."
