He was up 6-5 on the back of his best game but could not break the Daniel serve as they headed to the second-set tiebreak. There were chances for both, with Sheldon the more likely to succeed, but Daniel levelled and drew ahead 10-9, then Sheldon hit long, which gave the American-based Japanese player the victory.
“It is real relief. I kept myself in there and right now I am unsure what I am feeling but definitely happy to be in the finals,” said Daniel.
“It is a big win. Even though he wasn’t playing at his best, but to keep him there is a really important skill and that is going to be important in the coming years.
“There is a tendency to get really excited in those moments and anxious, so I told myself to keep doing what I have been doing. There’s a lot of energy from the crowd so there is a tendency to want to use that and hit a really big shot but you have to calm down.
“There’s such a nice vibe in centre-court. It was the first time I have played there yesterday – it is such a fun, relaxed and nice event. I was trying to get into Adelaide but saw I had a chance to get into the main draw here so I came and look where I am. It’s crazy.”
Daniel has won one ATP Tour title after winning on clay in Istanbul in 2018.
