It felt like the end of an era in Auckland, especially when Ferrer's ranking blew out to No46 in the world midway through the year — his lowest position since 2005.
But a tournament win in Bastad turned around his year.
He regained his mojo and belief, and his appreciation for the game and is, as he has said many times this week, playing without pressure.
"I still have motivation and I think I can improve my game," Ferrer said yesterday after his win.
"But my goal this year is to try to enjoy every game that I play. And to play centre court today was very nice for me."
Yesterday felt like a return to his glory days, with some moments of vintage Ferrer as he dismantled Joao Sousa 6-2, 6-2.
He ran down balls from some impossible situations, hit the lines with unerringly accuracy and produced some impressive angles.
"Today, everything was perfect," said Ferrer, who struggled to subdue wildcard Wu Yibing in the first round. "I played really good ... serving, returning.
"Today with Joao, we have a similar game and I can play with more time to play on the baseline. So I was more comfortable."
● Canadian teenager Denis Shapovalov made some big plays, but plenty of mistakes too, and in the end was no match for the class or power of Juan Martin del Potro last night.
Del Potro needed just 24 minutes to take the first set, and the match was done 6-2, 6-4 in 65 minutes.
No doubt Shapovalov, 18, is one for the future.
But this was del Potro, 11 years Shapovalov's senior, in cruise mode. Russia's Karen Khachanov, next up in the quarter-finals, should be worried.
