He lived up to that promise most in 2023 when he reached an ATP Masters 1000 quarterfinal in Madrid only two months before he cracked the top 50.
Hanfmann said it often boiled down to momentum.
“I was able to have a run where I just played a lot of matches, gained a lot of confidence and right now I feel like I have the level but I may not have that match rhythm, that confidence that goes with it, so I'm glad to pull it out today,” he said ahead of a second-round match against Frenchman Matteo Martineau.
“I don't think it's a huge difference in level (to now). It's just about winning matches,” he said.
“Sometimes it is like that and I think when you crack the top 50 you have a bit more of a target on your back and I had to mentally kind of get used to that in the tournaments I was playing with a lot of matches behind me, like no pressure.
“Then the things shift a little bit, but I'm right now, my ranking is not where it was, but I do believe I can come back there.”
