Ros Casares continued their irresistible march into the last 16 of the EuroLeague Women but were pushed hard by USO Mondeville Basket before claiming an 83-78 win.
DeLisha Milton was the driving force behind the win with 20 points and 15 rebounds, ensuring the hosts remain unbeaten at 7-0 atop Group D.
They can relax for their remaining three group games but USO (2-5) still have work to do if they are to progress.
Their dominant position in the standings may suggest the group is proving a walk in the park for the Spaniards, but this was anything but.
The visitors led by as many as 10 points early on before Valencia pulled level at 38-38 midway through the second quarter courtesy of a three-pointer from Katie Douglas (16 points and seven assists).
But they could not shake off their dogged opponents and could not get further than six points away from them.
With less than five minutes remaining, Paoline Salagnac (15 points and six rebounds) pulled the scores level again at 68-68 with a lay-up.
But that was as close as they got to reclaiming the lead as the Spaniards narrowly claimed their seventh victory.
