Right, off we go with this third and decisive set.

I didn't expect this one to still be going at this point considering how quickly Haddad Maia breezed through the first set.

That break in play really disrupted her. Confidence and momentum will now be with Navarro.

It gets worse for Haddad Maia as she sends her return long before Navarro serves to seal the second set.

We're all square at one set each.
