A Queen’s Cup semi-final between Alex de Minaur and Holger Rune was stopped twice due to medical emergencies in the crowd.
The match in West Kensington saw two separate worrying moments, but both of the audience members are believed to be OK.
The final four meeting between Rune and De Minaur was won by the latter 6-3, 7-6 (2) after the Australian saved three break points.
But that wasn’t before the first set was interrupted at 3-3 as medical personnel took to the stands to tend to a fan.
The match resumed soon after, but at 5-5, it was again stopped for a fan who had been taken ill.
Temperatures reached 28 degrees in west London, with supporters wearing hats and using umbrellas to find shade.
Commentator Greg Rusedski expressed his concerns for the fans, and explained that it would have impacted the players.
“This is really unfortunate for the players,” he said. “We really hope the person up top is alright.
“That’s already the second time it’s happened during this match and from a player’s point of view you always have a bit of concern for the spectator.”
Rune’s win sets up a final match against world no.2 Carlos Alcaraz, who can return to top spot ahead of Wimbledon with victory on Sunday.
