What would be the perfect volleyball position for my female lead?

Working on my romance novel. The female lead, Lauren, is the captain of the school's volleyball team and is on their way to the nationals.

Lauren's a very talented player and a good team leader. 17-years-old, standing at a height of 6'4 and half with great physical prowess. She's great at both offense and defense.

To be very honest, I don't know a whole lot about volleyball—which is why I need help.

What would be the ideal position for her?
