The former world number one has now won a WTA title every year for the last seven years, winning her first three in 2008, three more in 2009, six in 2010, six in 2011, two in 2012, one in 2013 and now one in 2014.
"I'm happy to have won my 22nd WTA title -- it's a great feeling. I'm happy how the final went today. I served well and pushed her around the court, and I really dictated the match," said Wozniacki.
Vinci added: "I tried to play aggressively like always but made a lot of mistakes. It's tough to play like that against Caroline because she puts everything back in the court, and it was tough for me to stay in the rallies today. But I'm happy with my week and Caroline just played much better than me."
