Surrey reached the T20 Blast final at Edgbaston with a six-wicket victory over Gloucestershire.
After Saturday was lost to rain, Finals Day eventually got under way at 15:15 BST on Sunday, with both semi-finals reduced to 11 overs per side.
Liam Plunkett (3-12) and Reece Topley (2-15) limited Gloucestershire to a modest 73-7, and Surrey reached their target with eight balls to spare.
The Brown Caps will face Notts Outlaws or Lancashire Lightning in the final.
That game will also be a shortened 16-overs-per-innings match, after the competition went into a reserve day for the first time in its history.
After being put in, Gloucestershire lost regular wickets as only three players made double figures, Benny Howell top scoring with 21.
It meant Surrey were able to adopt a steady approach to their chase and, although David Payne (3-18) impressed with the ball, Ben Foakes struck 20 before England Test opener Rory Burns guided them over the line with an unbeaten 12.
Should further rain make it impossible to finish the second game and/or final they will be decided by bowl-outs – but good weather is forecast for the rest of Sunday.
