Bromsgrove’s brittle batting surfaced again after being bowled out on 55 for the second week running.
After being embarrassed against Walmley last week, Bromsgrove suffered another batting disaster at Kenilworth Wardens.
Warwickshire prospect James Ord laid the foundation for a Wardens total of 216 for six by supplying 58.
But the fun and games were to follow as Shitansu Kotak claimed five for 17 while James Jordan included a hat-trick in his five for 25 return as Bromsgrove duly collapsed again.
At least Bromsgrove still remain above bottom spot.
Moseley made sure they continue to prop up the table following their four wicket defeat against Kidderminster Victoria.
Worcestershire paceman Imran Arif picked up figures of five for 28 as Moseley were removed for 130.
Neil Pinner then plundered 51 as Kiddy reached a winning 131 for six.
Knowle and Dorridge return to top spot after a nine wicket beating of Leamington Spa. Former Warwickshire player Nick James returned fresh from his England 12th man duties against Australia in Cardiff to claim three for 38 as the Spamen were restricted to 142 for seven. South African Jacobus Pienaar then struck a quickfire 83 not out off 59 balls as Knowle and Dorridge reached a winning 143 for one in just 20 overs.
Former Glamorgan skipper David Hemp kept Pienaar company with 39 not out on his first Birmingham League appearance of the season.
Wolverhampton are two points adrift of leaders Knowle and Dorridge following an emphatic 111 run win over arch rivals Himley.
Former India test player Sairaj Bahatule struck 70 not out while wicketkeeper Chris Brook added a further 52 as Wolves reached 199 for seven.
Himley crashed in reply to 88 all out as Bahatule bagged four for 24.
Shrewsbury continue their climb up the table after beating Barnt Green by five wickets.
Warwickshire Second XI coach Dougie Brown supplied 48 of the Green’s 208 for eight total. Shrewsbury then swept to their target in reply as Ed Foster fired 80 and found support from Ryan Bishop’s 48 while Wes Robinson struck a further 41 not out.
Rain almost certainly saved reigning champions Walsall from defeat against Walmley. Shropshire allrounder Jack Shantry scored 51 as Walsall were restricted to 131 all out after Hamza Nadeem with four for 27 and South African Greg Ricketts who took three for 60 caused most of the damage. Shantry then struck back with the ball by taking four for 35 but Walmley remained well placed to win on 101 for five when rain arrived.
