The Frenchwomen continued her sizzling form, easing past Kvitova 6-2, 6-4 on the hard courts of Cincinnati to claim her third career Masters 1000 trophy and a tenth WTA title.
It was business as usual for Garcia - who has won no less than 33 matches and three titles this season - as she raced to a 4-0 lead in the opening set. Kvitova rallied back to hold serve to love and then pushed to earn two breakpoints in the following game, but couldn't convert.
In the second set, Garcia broke early then Kvitova called a medical timeout as her trainer came to work on her leg. The Czech star regrouped to hold serve but again failed to convert breakpoints as Garcia moved her WTA title count into double digits.
"Pure joy, I think, just happiness," Garcia said in her post-match press conference.
"Every single win is very important. Every title is very special, [WTA] 250, 1000, it's always very hard to describe it. It's not happening so often, and you have to really enjoy it. I'm really grateful for this great week of tennis, and to win another title, it's very special.
"Every match, every day was a new day, new challenge. Every time I had to be focused on myself, on my game, what can I do, how I can be more aggressive, how can I improve. Just one day at a time I ended up here today in the final and now lifting the trophy.
"The [WTA] 1000, everything goes so fast. You have to refocus every morning. It's a tough challenge, but I'm really happy the way we made it through."
