Hunslet Nelson ended Bowling Old Lane's hopes of retaining the Jack Hampshire Cup when they defeated them by five wickets in the quarter-finals.
Opener Andrew McIntosh (53) got Nelson off to a flying start when they replied to Old Lane's score of 178, and skipper Will Stiff (40no) completed the task of steering Nelson into the semi-finals.
Amjid Hussain (36) and Ahsan Butt (31) got starts for Old Lane but couldn't go on to make the sort of contribution their side required as Stiff (3-34) and Saad Shaik (3-21) kept the run rate under control.
Yeadon scored a comfortable seven-wicket win in their clash with Carlton just 24 hours after losing the leadership of Championship One to their rivals.
They quickly reduced the Wakefield side to 25-4 and only an unbroken last-wicket stand of 65 between Nick Busby (39no) and Clark Harrison (37no) boosted their score to 142-9.
Andrew Robinson (3-23) was the most-successful bowler but Gareth Lee (2-14) and Paul Machell
(1-14) kept runs at a premium in their eight-over spells.
Yeadon's reply was dominated by a second-wicket partnership of 101 between opener Rob Smith (36) and their impressive overseas player Sarmad Hameed.
The stylish Hameed hit three sixes and 11 fours as he added to his growing reputation with an unbeaten 83.
Wicketkeeper Jack Seddon proved to be a big hit as Buttershaw St Paul's defeated Conference side Sandal by 85 runs.
Seddon hit eight sixes and seven fours while making an unbeaten 85 from just 43 balls which propelled Buttershaw St Paul's to 271-7. His boundary barrage built on the earlier good work of opener Jonathan Burston (80).
Sandal were going well at 121-2 but faltered as the required run rate climbed. Danny Riley's 66 was the highlight of their 186 all out. Skipper James Sawyer (4-47) and Aidan Winnard (3-21) were the key wicket takers.
In-form Birstall sealed their place in the last four with a hard-earned 22-run win over plucky Conference side Great Preston.
Birstall built a challenging total of 214-6 through the efforts of Eric Austin (48), Brad Lay (38) and Ashley Burton (36no).
Great Preston put up a good fight before they were finally bowled out for 192. Australian Tyson Freeman (57) produced another important contribution while Kieren Thurston hit 37. The best Birstall bowler was Sair Ur Rehman 3-37.
The draw for the semi-finals will be made tomorrow and publshed on this website around 7.30pm.
