Griekspoor v Alcaraz
Spain's Davis Cup hopes - and the chance of another Rafael Nadal appearance - rests on the shoulders of Carlos Alcaraz now.
Alcaraz won the French Open and Wimbledon this year, but his season has fizzled out slightly and he failed to reach the knockout stages of the season-ending ATP Finals earlier this month.

An excellent charm offensive from Van de Zandschulp, there.
He will not be a popular man in Spain.
Remember, he also ended Carlos Alcaraz's bid for US Open glory in September.
Stay in the hotel tonight, Botic.

You knew Rafa wasn't gonna slope off with his tail between his legs.
And the Spanish fans wouldn't let him.
A chant of 'si, se puede' - essentially 'yes, you can' - rang around the arena as they told him anything remained possible as he battled to avoid defeat.
Ultimately, he couldn't. Nadal waves to all sides of the adoring crowd.

Here's what Botic van de Zandschulp had to say following his victory over Rafael Nadal:
"At the beginning I think we were both nervous. The first games didn't go smoothly. The crowd was tough, understandably.
"That is what it is to play against Rafa in Spain. He is probably the biggest sportsman in Spain to have ever lived.
"I have to say it is tough to close out a match against him, knowing it could be his last. I felt I was hoping a bit more than going for it. I went for it and it helped in the end."
On the support from the Dutch supporters in the crowd, he added: "It was unbelievable. I needed it. There were too many people from Spain here cheering for him.
"If I was sat at the side of the court I would have been cheering for him too."
