Sprowston recorded an incredible one-wicket victory to reclaim top spot in the Premier Division on a day when morning leaders Norwich were held to a draw.

The title challengers looked down and out against Diss when they slipped to 118 for for nine chasing a target of 192 – but the last pair of Geoff Roff and Sam Niblett had other ideas. Batting sensibly and taking minimal risks they pulled off the unthinkable with an unbroken partnership of 75 in 29 overs to leave everyone at the ground stunned at what they had just seen. Roff finished unbeaten on 46 from 91 balls while Niblett was on 25 from 92 balls.

Diss had produced a comeback of their own to get close to the 200 mark. They had struggled to 47 for five before an excellent 77 from Rob Tooke guided them to respectability.

Norwich are now two points behind Sprowston in what is turning into a thrilling title race after having to settle for 13 points from a 90pc winning draw against Vauxhall Mallards A. Their total of 221 all out featured good contributions from former Norwich City footballer Chris Sutton (40 not out) and his son Frankie (38) while Alistair Horsley also chipped in with 40 in the face of some good bowling from Ryan Pearce (five for 57). Steve Goldsmith led the reply with an unbeaten 77 but Mallards had to settle for a share of the spoils as they finished on 202 for six after 50 overs.

The third side in the title race are Downham and they are now just a couple of points behind Norwich following a nine-wicket romp against Stow, who were dismissed for just 108. Addam Todd hit an unbeaten 70 as the game finished early.

At the other end of the table Cromer recorded a long overdue third win of the season to move out of the bottom two at Stow's expense. They dismissed North Runcton for 131 at the Norton Warnes Ground after Matthew Warnes (66) and Malcolm Cloete (51) had guided them to an all out total of 188. Anthony Robinson was the star man with the ball for Cromer, taking five for 45. Marcus Glenister had a great match for Old Buckenham, scoring an unbeaten 101 and taking four for 22 as they beat Ashmanhaugh and Barton Wanderers.

Brooke went marching on at the top of Division One as they beat Topcroft by 10 wickets. Their opponents set a decent target of 187, with James Goodfellow scoring 56 and Tom Nudd taking five for 44, but the Brooke openers then took control. Rob Panter finished on 114 not out, his second ton of the season, while John Whitehead contributed an unbeaten 62.

Brooke's nearest challengers Lowestoft and Swardeston A also won, seeing off bottom two Dereham and Bradfield respectively.
