Oxfordshire captain Max Mannering returned career-best figures of six for 17 to trigger a spectacular Wiltshire collapse on the opening day of the NCCA Cluberly Championship Western Division One match at Corsham.

There was no hint of trouble when Wiltshire openers Jack Mynott (41) and Cyrus Shafi (32) added 77 after Ed Young had won the toss and opted to bat first but the collapse started after Shafi was bowled by Ben Lucking.

Wiltshire lost ten wickets for 46 in 21 overs and were dismissed for 123 before lunch with off-spinner Mannering returning the remarkable figures of 12-4-17-6.

Oxfordshire’s batters stuttered at the start of their first innings but a fifth wicket partnership of 139 between Luke Hayes (62) and Freddie Smith took them past Wiltshire’s total and into a commanding lead.

Smith was unbeaten on 89 at the close with Oxfordshire 266 for six and 143 in front.

Half-centuries from Callum Harvey and Seb Linnitt and solid batting down the order helped Western Division leaders Devon to post 342 against Berkshire at Blundell’s School.

James Horler (30) and Sam Elstone (48) laid solid foundations with an opening partnership of 79 with Gloucestershire Academy all-rounder James Matravers again contributing useful middle order runs with 43.

Off-spinner Euan Woods took four for 63 and gave Devon most to think about and then shared a half-century partnership for Berkshire’s second wicket with acting-captain Rhys Lewis. Opener Will Hamilton went for a duck on debut but Lewis (34 not out) and Woods (29 not out) took Berkshire to 69 for one.

Eastern Division One leaders Northumberland piled up 420 for eight against Cambridgeshire at Sawston thanks to a brilliant career-best 177 from John Oswell.

Oswell struck 24 fours and four sixes in his 157-ball innings and shared a fifth wicket partnership of 207 with former Durham all-rounder Jonny Bushnell (53).

There was no respite for Cambridgeshire after Oswell departed as Oli McGee rattled up a quick half-century which took Northumberland past 400.

Jack Loveday and Ben Claydon shared six wickets for Cambridgeshire for whom openers Ben Saunders and Callum Guest responded with an unbroken partnership of 52.

Defending national and Eastern Division champions Buckinghamshire hit back hard against Suffolk at Chesham.

Buckinghamshire struggled to 125 for seven at lunch but rallied to 205 all out thanks to a half-century from Ewan Cox and handy runs down the order from Rhys Nicholas (28), Ed Bragg (26) and captain Conner Haddow (28).

After a team effort with ball, Suffolk ran into trouble with the bat and ended the day on 123 for eight with seamer Tom Weymes again enjoying himself at Chesham. Three weeks ago Weymes took his maiden five wicket haul in the victory over Staffordshire and he ended the day with figures of four for 15 from nine overs.

Shropshire’s former Glamorgan and Leicestershire pace bowler Roman Walker followed up his eight first innings wickets against Wales NC last week with seven more against Cheshire at Nantwich in Western Division Two.

Walker’s opening burst of five for 18 in 12 overs reduced Cheshire to 74 for six at lunch but they recovered to 222 all out thanks to half-centuries from captain David Wainwright and Dan Wilson and 30 from Jack Collett.

Shropshire ended the day on 90 for two with opener Finn Jones unbeaten on 47.

Cornwall dominated the first day at Ebbw Vale where they put Wales NC in, bowled them out for 129 and then reached 298 for four for by the close.

Cornwall’s new ball pair of Will MacVicar shared eight wickets to help dismiss Wales inside 44 overs, then Alex Blake and Alfie Macdonald shared a third wicket partnership of 149 which gave them the lead.

Former Kent batter Blake made the fourth Championship century of his career with Macdonald continuing his excellent recent form with 61.

MacVicar completed a good day’s work with a quick unbeaten half-century to help Cornwall build a lead of 169 with power to add in the remaining 28 overs of their first innings.

Matt Taylor made Bedfordshire’s first half-century of the Championship season but Lincolnshire still dominated the first day at Dunstable in Eastern Division Two.

Despite Taylor’s efforts, Bedfordshire were dismissed for 178 after they had won the toss with no other batter reaching 30.

Seamers Matty Mills and Tom Shephard shared six wickets in a solid team bowling effort by Lincolnshire who ended the day only 48 behind with nine wickets intact.

Sam Jarvis went for a first ball duck but Nick Keast (67 not out) and Sam Evans (58 not out) had added 122 for the second wicket by the close.

Former Derbyshire and Kent off-spinner Hamidullah Qadri took four wickets to help Norfolk dismiss Cumbria for 172 at Sprowston.

Cumbria owed much to former Cheshire batter Calum Rowe’s diligent 43 on Championship debut for them and 34 from new captain Matt Sempill in a fifth wicket stand of 70.

Wicketkeeper Sam Bates contributed 35 from number eight but Norfolk were only 36 behind at the close with eight wickets in hand.

Sam Arthurton (54) and Nathan Muggeridge (39 not out) opened with a partnership of 87 with Muggeridge and Alfie Cooper (30 not out) then adding 40 for the third wicket after Arthurton and Ben Wilcox, who was stumped for a 19-ball duck, departed in quick succession.
