Great Britain will need to win both singles rubbers tomorrow to win this Davis Cup tie.
As it stands, Cameron Norrie and Liam Broady will play Albert Ramos-Vinolas and Roberto Bautista Agut respectively, but that could change.
All eyes for Britain will be on Kyle Edmund, and if he's had enough time to recover from that hip niggle.
We'll be back from 10:00 GMT tomorrow to bring you all the action from Marbella. The report from today's rubber is here - have a read of that, and we'll see you back here tomorrow!
