Having won the toss, Singapore elected to bat and despite losing Chaminda Ruwan for a duck early on, Chetan Suryanwashi and Buddhika Mendis added a commendable 92 runs before the wicketkeeper-batsman departed after being caught by the ever agile Jeremy Frith.
Jamie Nussbaumer once again proved key for Guernsey snapping up three wickets as did Stuart Bisson who also claimed three, young bowler David Hooper also showed his worth once again, this time taking two wickets including that of key top-order batsman Anish Param.
However, despite some good bowling, Mendis managed to add 77 runs before being caught by GH Smit and Param 43 and at the conclusion of the host's 50 overs it had made the sizeable target of 224 for the Channel Island team.
In response, Guernsey's batsmen, apart from Frith, failed to fire for the team. Frith once again appeared to cornerstone the side's innings with his impressive shot selection which included him emulating the shot made famous by Tillakaratne Dilshan of Sri Lanka, scooping the ball over his and opposition wicketkeeper's head to add four runs to the total.
Frith's batting though could not save the visitors against Singapore's fast bowlers and the team struggled to put runs on the board and keep up with the required run-rate. The middle-order didn't help Frith, captain Stuart Le Prevost and Tim Ravenscroft making eight runs between them.
Things were looking positive for Guernsey when Ben Ferbrache joined Frith in the middle but the 23-year-old departed after attempting to hit to the on-side, failing and was caught by the ever athletic Param leaving Guernsey five down with 118 on the board, much to delight of the home supporters.
In the end, Saad Khan's men proved too strong and Guernsey never got into the flow of things and the side fell some 78 runs short of the target.
Guernsey coach Andy Cornford was obviously disappointed with the loss but had some praise for the likes of Hooper and Frith.
"It was a tough game; we always knew playing the hosts was going to be tough. I was really pleased with the way we bowled and fielded and I thought at one stage they were going to be set for a bigger score than they achieved.
"Young David Hooper made a particularly good show with the ball today, but our batting let us down today – we didn't perform well as a unit. Frith played well again but as a unit we didn't perform well today."
When asked if the side relied on Frith's batting, Cornford admitted that this was the case to an extent: "With someone as consistent as Jeremy we do tend to bat around him as we know he will score runs. However that being said, our batters need to perform better and they have got to deliver in this tournament.
"We love being in Asia and enjoy playing here so the conditions are not troubling us at all," concluded Cornford.
Man of the match Mendis said: "It's pleasing to get another win under our belt, I felt we could have scored more runs today but over 220 was a good score on this ground all the same.
"I'm happy with my knock but wish I could have stayed round longer – I have to say Guernsey did challenge us today, it's like they are always there in the field. They do rely on the likes of Jeremy Frith but he's a good player – at the same time the side is well-rounded and has very good basic skills which helped them against us today despite their loss.
