Owain Jones made an imperious unbeaten 121 as Steyning disdainfully disassembled Lewes Priory’s bowling attack in their 68-run victory on Saturday.
Having been put in to bat by the visitors, Steyning raced to a total of 240-4, working at a run-rate of 7.3 before declaring after only 33 overs.
Jones hit half of the runs alone, and was initially supported by his brother Hywel, who was eventually out for 52.
Steyning skipper Dave Kennett said: “This season we’ve been very consistent with the bat, reaching 200 most weeks. Owain was fantastic on Saturday, I don’t think he gave a chance all afternoon.
“He’s obviously a very good player and he’s probably playing a lower standard than he should be at the moment.”
In response, Lewes started brightly - thanks mainly to captain Andrew Hartridge, who passed 50 runs before Steyning could strike.
However, Ashley Mwenda made the breakthrough, taking the wicket of Jacob Lee for only eight runs.
Mwenda - who took 3-29 - also took the wicket of Hartridge for 60 as Lewes lost their next four wickets for just 20 runs.
Jeremy Bates (57) offered some resistance, but after a sturdy partnership for the sixth wicket, Steyning removed Lewes’s final five wickets for 17 to win by 68 runs.
Kennett added: “We’ve got five very good bowlers, it’s quite nice for a captain – I can throw anyone the ball if it’s not going well. Lewes started very well, their skipper got them off to a good start.
“After tea, Ashley came on and changed the game really, he took three quick wickets.
“We’re not far off promotion, but Portslade keep winning, which keeps a little bit of pressure on. We’re 56 points clear, which is still quite a big gap on current form, so that’s our main aim now – to push on and win the league.
“If Portslade keep going as they are, we’re going to need three more wins and five bonus points.”
