The euphoria of a dramatic opening-day win sends Norfolk into their second Unicorns Knockout Trophy fixture in good spirits, safe in the knowledge that they still have room to improve.

Garry Park's final-ball wicket sealed an exciting four-run victory at Cambridgeshire and captain Chris Brown is looking for his team to continue on that upward curve in their next Group Three fixture, when Lincolnshire come to Manor Park on Sunday.

'It was a really tough first game of cricket which went down to the last ball,' Brown said.

'We had a long chat in the changing room after the game where we performed very well on a cold day, however there are still some areas that we can improve on.'

Lincs were not in Norfolk's group last season but the teams met in the quarter-finals, when Norfolk fell 19 runs short of their target at Grantham. Sam Kelsall led the way with the bat that day for the hosts, scoring 76 and taking three wickets, but is now playing for Staffordshire.

The victors then lost at Northumberland in the semi-finals, with the match abandoned and the hosts winning by 90 runs under the Duckworth Lewis method.

Lincs kickstarted their season last weekend by avenging that defeat with a 181-run win over Northumberland at Grantham, Mohammad Azad scoring 78 in a total of 272 for seven, before the visitors were bowled out for just 91, with Alex Willerton taking four for 16.

'They are a strong side, arguably the strongest in the group, and have a couple of new players so we will have to be on top of our game,' Brown continued.

'We can improve on our discipline with the ball, just in terms of extras, and if we can get consistent contributions throughout the top order then we won't be far away.'

There is just one change to the team, as Matt Plater is heading back to Durham University for an exam, so James Hale comes in to make his one-day debut for Norfolk – with play scheduled to start at Manor Park at 11am.

Norfolk (v Lincs): Ben France, Sam Arthurton, Garry Park, Jordan Taylor, Lewis Denmark, James Hale, Ashley Watson, Chris Brown (C), Brett Stolworthy, Sam Groves (WK), Adam Todd
