Worcestershire secured a home semi-final in the Royal London One-Day Cup by beating rivals Warwickshire by one wicket in a thriller at Edgbaston.
Joe Leach's side staved off a late fightback by Warwickshire to secure the narrowest of victories, top spot in the North Group and a semi-final against Nottinghamshire or Kent.
Chasing Warwickshire's 292, Worcestershire seemed cruising when they needed 21 from 11 overs with five wickets in hand.
But they ended up scrambling home by one wicket as Dillon Pennington (three from 20 balls), on his first-team debut, and Ed Barnard (13 not out from 14) got the job done.
Put in, Warwickshire totalled 292 for seven with Sam Hain (68 off 84 balls), Tim Ambrose (75 off 73) and Will Rhodes (69 off 56) keeping Warwickshire in the game.
Worcestershire's reply was then given a lightning start by Moeen Ali, who rode his luck for 114 off 74 deliveries - pyrotechnics which put Worcestershire in the box seat, though it was Ben Cox's classy 80 off 85 balls, which brought the best batting of the day.
Nottinghamshire stayed on course to defend their Royal London One-Day Cup trophy after thrashing Derbyshire by eight wickets at Trent Bridge.
The holders, who defeated Surrey in last year's Lord's final, bowled their neighbours out for only 110 in 35 overs, with Jake Ball and Matt Carter sharing seven wickets.
Ball, playing his final game for Notts before joining up with England's One-Day squad, finished with four for 29, while off-spinner Carter claimed three for 19.
Riki Wessels wasted little time in leading the home side to a resounding victory as he made 63 from only 28 balls, with six fours and five sixes.
Yorkshire edged through to the knockout stages for the fifth year running by beating already eliminated Northamptonshire at Headingley.
The White Rose county claimed a fourth successive North Group win by chasing 242 with four wickets in hand and an over remaining.
But they missed out on a home semi-final eliminator tie having not reached their target in 41 overs in order to better Nottinghamshire's net run-rate.
David Willey (71) and Jonny Tattersall (52 not out) were Yorkshire's match-winners.
South African opener Cameron Delport fired a century as Leicestershire climbed off the foot of the north group table with a five-wicket win against Durham.
Delport struck 122 off 128 balls to help Leicestershire rseal victory with almost six overs to spare, reaching 243 for five after Durham had been restricted to 240 all out.
Leicestershire's Colin Ackermann completed a half-century, while an earlier unbeaten 61 off 56 balls from Durham's Ryan Davies proved in vain.
