Carew, Cresselly, Llangwm and Haverfordwest are through to the semi-finals of the Thomas Scourfield and Sons Harrison-Allen Bowl.
Cresselly had a comfortable win at home to Whitland after scoring 156 before being dismissed.
Julian Arthur with 34, including three sixes and three fours, and Ryan Lewis with 30, with two sixes and four fours, were the leading run scorers for Cresselly as Matthew Davies took 4-46 and Daniel James 3-52.
Number 11 Daniel James (13) was the leading scorer and the only other batsman to reach double figures was opener Edward John (10). Richard Harris put the ball on the spot and took 4-15, with South African Morgan Geldenhuys (3-11) providing ideal support in a lively psell of fast medium bowling.
Lamphey were restricted to 85-7 at home to First Division leaders Carew. Left arm pace bowler Scott Helmich (3-13) and Rhys Davies (2-26) picked up most of the wickets, with only three Lamphey batsmen reaching double figures.
Skipper Rob Mathias was going well before a pulled muscle forced him to retire hurt for 19.
Openers Ian Sefton and Nick Scourfield knocked off the runs fairly quickly to reach 89 without loss.
The match-winning boundary by Sefton enabled the stroke player to get to 50 with two sixes and six fours, whilst Scourfield finished on 25.
Llangwm had a nine wickets win at Fishguard after holding the home team to a total of 55-9. Chris Inward and Luke Brock each took three wickets. Llangwm raced to 56-1 in reply, with Williams Beresford 24 no and Joseph Kiff 25no.
Third Division Crymych gave First Division Haverfordwest a real fright chasing a Town total of 166-1 after excellent batting by Danny Potter (75no) and David Davies (65no).
Crymych reached 154-8 in a determined victory bid, with forceful batting from Elgan Vittle (51), Rhys Davies (30) and Jacob Lloyd (21no).
Spinner Nick Dyer took 4-53.
