In a night of firsts, Rhys Murphy opened his account for the club on 27 minutes before having to be withdrawn with a hamstring injury five minutes later.
Substitute Remeao Hutton doubled the advantage with his first senior goal two minutes after the break, before Aswad Thomas grabbed one back for the hosts.
Keen to avoid a nervy ending, Tom Whelan scored his first for the club inside the final 10 minutes to leave Sarll a happy man.
“I thought we were very professional actually,” he told YTTV. “I said at half time, I just didn’t want us to be naive, and to show naivety. The way we started the second half was fabulous.
“Our forward running was good all night. I was really hard on Matt Worthington and Tom Whelan on Saturday and I thought they were terrific, as was Carl Dickinson when he came on. Myles Hippolyte played 90 minutes after being out for the count a couple of weeks ago. Remeao Hutton, who I left out tonight, came on and was so disciplined, and wee Charlie Lee when he came on was massive as he always is. So it’s a good night.
“It’s lovely to win and I love sharing wins with people. I’d rather they be shouting my name and smiling, rather than singing that ‘you’re going to get sacked in the morning’ and cursing at me! So I love sharing that moment with our supporters, who again worked hard to get up here.”
The win – which moved the green and whites to three unbeaten – did come at a cost.
Captain Lee Collins was forced to follow Murphy in limping to the touchline with both now likely to miss out on some game time.
“It’s a hamstring for Murphy and Lee Collins is the same. So they’ll be bad ones for us. Rhys Murphy is sub-30 and Collins is a little bit older.
“Normally the older ones take a little bit longer. But it was nice to have Carl Dickinson ready and willing to go, and how good was he? I thought he was very good. Everyone looks better when you win.”
