Erin - A spectator at the US Open died after collapsing in the grandstands, organisers said on Friday.
The 94-year-old man was given first aid by emergency services after being reported to be "pulseless and non-breathing," a statement said.
"The subject was later transferred to an on-site ambulance, where he was pronounced dead," officials said.
"No foul play is suspected and the death appears to be of natural causes," a statement added.
