Steyning captain Dave Kennett is targeting four more wins to seal his side the Division 4 title.
The runaway leaders are still 56 points clear at the top of the table after a 33-run victory away to Hellingly on Saturday.
Kennett’s sights are now on the league crown and he said: “It would take a miracle for us not to go up, all the focus is now on winning the title and going up as champions.
“We think four wins out of the last six will guarantee that if Portslade keep up their good form and win their remaining games.”
Opener Owain Jones (50) top-scored after Steyning won the toss and opted to bat.
Ashley Mwanda hit 27 and Kennett 36 as they posted 209 in 45.4 overs.
In reply, Steyning grabbed a couple of early wickets, but an unbeaten 82 from Greg Devlin meant Hellingly were closing in on the total with 174-7. But a fine second spell by Owain Jones (6-55) saw him polish off the tail as the hosts closed on 176.
Kennett added: “Hellingly played well and could have won the game themselves. We batted very ordinarily with most getting starts and then getting themselves out, but we got to our target of 200.
“With the ball, we started well with couple quick wickets, but then Hellingly’s middle order batted well.
“Although I didn’t think we would lose, I wasn’t sure we would win, but my players really stepped up towards the end of the game and we never panicked and our quality got us over the line in the end.”
