Rafael Nadal fought through injury to come from behind to beat Taylor Fritz and reach the Wimbledon semi-finals.
The Spaniard, who had a medical timeout at the end of the second set and struggled with his movement for long spells, won 3-6 7-5 3-6 7-5 7-6 (10-4).
It keeps Nadal's bid for a calendar Grand Slam on track and sets up a semi-final against Nick Kyrgios.
Nadal, who had strapping on his abdomen in his previous match, was bothered by the same issue again.
The first question he faced after the forehand winner that sealed victory, in a match that at one point he looked like he might not be able to finish, was 'how did you do that?'
It was the one on anyone's lips who witnessed the events on an enthralled Centre Court.
"I don't know," the 36-year-old said.
"The body in general is fine, but in the abdominal [area] something is not going well, being honest. I had to find a way to serve a little bit different.
"For a lot of moments I was thinking I would not be able to finish the match but the crowd, the energy, thanks for that."
