3.50pm: Invincibles feel they're ahead of the game here, thanks to patience at the top and a blistering finish courtesy of Sam Curran's 21-ball fifty. They had pootled along to 56 off 55 before putting the hammer down, scoring 91 off the remaining 45 balls. Will it be enough for a third win from four? Vish will be along to find out shortly

Here's Curran speaking to Sky: "Think we played well, spoke about the new ball being tricky. We knew if we got to 40 off 40 with wickets in hand we could go at the end, with a smaller side to target. [Billings retiring] Very selfless, that's the way the game is moving. Bilbo just said 'I'm off', fair play to him, hopefully it works. That's the reason we batted, thought it would get slower. Start well in those first five sets and hopefully we've got enough."

Ellis is back, having conceded 40 from 15 balls so far

"They were 46/2 after 50..." notes DaWolf, "what a change."
