Brook, hosting Grayswood for the second time in four days, needed a big score if they were to avoid a second defeat. Stand-in skipper Andy Gloak won the toss and took the new ball with Iain Jackson, but Brook openers Tom Smith and Toby Johns showed plenty of grit and were still together after 16 overs.
Almost inevitably, it was Jon Ashworth who broke the stand. Gloak dismissed the dangerous Robin Hudson, but most of the work-load was then shared by spinners Ashworth and James Atkinson.
Tom Williams knitted the innings together with a well-paced 67 not out. Rhodri Williams gave valuable support and Brook took 60 off the last eight overs to post a respectable 178-7 from 48 overs.
Needing to score at 4.2 an over, Grayswood played around Tom Barnardo who produced another masterful innings for his side.
At 94-3, Atkinson came in to hit a run-a-ball 47 not out and he and Barnardo added 87 in quick time. The opener finished unbeaten on 81 (105 balls) and the champions cruised home with nearly five overs to spare.
Headley needed a 200-plus total after being put in at Hollowdene and looked on the way to a decent score at 45-1 and then 80-2. But it all went wrong when Frensham brought left-arm spinner Tim Knight into the attack and he promptly dismissed Gavin Arend and Zach Benstead (42).
Knight, having a great season thus far, went on to wreck the innings with 7-29 in 12 overs – his best return in the I’Anson. Frensham held their catches and Headley crumbled to 109 all out.
The inadequacy of the total was soon evident as George Breddy (49) and Tom Charman (35) hammered the opening bowlers and rattled up 75 before Graham Badland broke the partnership.
Mike Constantaras bowled a tight spell, but the damage was done and Frensham knocked off the runs in just 14 overs, with seven wickets intact.
Blackheath had marginally the better of a high-scoring draw against Puttenham, although the visitors came within 12 runs of victory. Put in by James Crouch, Blackheath soon lost Will Melhuish to a run-out, but Rob Parrott (61) and Mitch O’Dwyer shared a 100 partnership for the second wicket.
Australian O’Dwyer was three short of a maiden I’Anson century when he was trapped in front by James Crouch and Pete Melhuish declared at 208-7 after 46 overs.
Puttenham didn’t get the best of starts, but newcomer Mike Wicherek kept them in contention with a fine innings. The lower order all chipped in, with John Crouch making 23, but Will Melhuish finally had Wicherek caught for 61 by Alex Bertola and Puttenham fell just short on 197-8 – six points to Blackheath’s eight.
Tilford, missing a number of regulars, were inserted by Grayshott and struggled for runs on a slow wicket against a strong attack. Veteran openers Chris Wilson and Gavin Nesbitt managed only 27 runs in 18 overs before being separated.
The home team then slumped to 45-4, with first-change Andy Wheble taking three wickets.
Mark Ramesar and Huw Town-Jones forged a partnership of 50, but the return of Kiaran Wells signalled another collapse and Tilford finally laboured to 119-9 off the maximum 48 overs.
Wells finished with 3 for 19 off 12 overs and Wheble took 3-15 off nine.
Grayshott soon lost Gary Hunt to an excellent catch by Matt Bozier at point, but thereafter coasted to victory. Young opener Alistair Wheble batted soundly for his 42 and shared partnerships of 33 and 65 with Matt Jackson and Nathan Phillimore.
Phillimore made a swift 57 not out, including eight fours and a six, and hit the winning boundary with 10 overs to spare.
Chiddingfold must have been anticipating a first win of the season after finding batting form and amassing 241-7 against Dogmersfield.
Skipper Dean Spencer (56) and Tom Gleave put on 115 for the second wicket and then Matt Barnett hit an aggressive 40 as he and Gleave added a further 84 runs. Gleave was finally caught for 120 off 131 balls, including 12 fours and five sixes, and a good declaration left Dogmersfield needing 242 to win.
The visitors were equal to the task. The Chiddingfold bowlers could not contain the Raja opening partnership (Z Raja 45, S Raja 58) and after that flying start, Dogmersfield never looked back. Dhaniyal (33 not out) played a fine supporting innings and the middle order all chipped in as Dogmersfield motored to a four-wicket victory with nine balls to spare.
