The Aegon Championship final between British number one Andy Murray and French fifth seed Jo-Wilfried Tsonga at Queen's has been held up by rain.
Mindful of a forecast of prolonged rain in W14 on Sunday afternoon, tournament directors brought the final start time forward from 1430 to 1200 BST.
Morning showers prevented an on-time start, but officials are still hopeful of play at some point on Sunday.
Should that not be possible, the final will be on Monday at 1230 BST.
"The good thing about the British is that we have a sense of humour when it comes to the weather," tournament director Chris Kermode told BBC One.
"We've been told that we have a window of opportunity to play later this afternoon and we will wait as long as we can. We intend to play today.
Piers Newbery BBC Sport Piers Newbery on TwitterThe latest from Queens; still raining and definitely no play before 1500. Possible "window" after that but unlikely, I'd say.
"We might not wait until a 1900 BST start, for example, out of respect for the players, but we'll delay it as long as we can. We're talking to the players at half-hourly intervals.
"If we don't get any play today, though, the final will be at 1230 BST on Monday and we're finalising contingency plans as we speak."
