I nearly threw in towel in Thiem battle: Del Potro
Juan Martin del Potro confessed that he considered retiring in the darkest moments of what turned out to be a miracle 1-6 2-6 6-1 7-6 6-4 comeback over Dominic Thiem in the fourth round of the US Open.
But the 2009 champion at Flushing Meadows instead set up a rematch of his victorious final against Roger Federer as he played on through the effects of a fever.
"I was thinking to retire in the middle of the second set because I couldn't breathe, I couldn't move well. Dominic was dominating the match so easy," the Argentine said.
"But when we started the third set, I broke his serve very quickly and won the set in 20 minutes.
"I took all the energy from the fans. That's what I did in the end, just kept fighting. I didn't give up."
Del Potro, whose career has been repeatedly interrupted by wrist surgeries and rehab, now finds himself facing Federer yet again in New York.
The Swiss leads their series 15-5, and has won the last three matches between the pair - including their most recent meeting in Miami in March.
