Into the final and she thrived as the frontrunner 6-3, 6-4 versus world No.15 Amanda Anisimova, writing “Queen of Queen’s” on the courtside broadcast camera.
"It means a lot to me, because I'm 37-years-old and I won this trophy today," said Maria, who halved her ranking from No.86 to No.43 on Monday.
"People were always saying, 'Oh, now maybe it's time. You are too old. You are...' Whatever reason they say sometimes.
"I'm a good example that even in my age you still can win big trophies. I'm super proud of myself that I could win this tournament, because actually, I believed always in it, and my husband too. That's why we kept also going, because there was always this belief that I can win big tournaments and that I can do great things on the court."
Maria’s two daughters and husband-coach Charles had a front row view of Maria’s sublime showing in west London.
"It's such a special moment for all of us, like a family together," said Maria, undefeated in four WTA finals. "We won this trophy together, because we stick together and we are doing everything together. So it's not like only me that I won this trophy today. It's like my whole family won this trophy."
