Scotland leapfrogged The Netherlands to clinch the Quadrangular Series on NRR after they and Ireland finished on four points.
It was a thoroughly ruthless display by Scotland, who blew away Oman in a powerful opening bowling blitz which saw the hosts reduced to 13 for 4 and 38 for 5.
Ali Evans (2-10) set the tone with a wicket maiden in the first over, and with Gloucester debutant Adrian Neill (3-21) and Mark Watt (3-20) each picking up three wickets, the result was rarely in any doubt.
Mohammed Nadeem (29) and a late cameo by Sandeep Goud (31*) saw Oman post a well under par 111.
After a brief opening flurry from George Munsey (16), Scotland were wobbling ever so slightly at 42 for 3.
There was an immediate response from Scotland as the previously out of form Richie Berrington, who clubbed 6 fours and cleared the ropes twice in a powerful unbeaten 47 from just 29 balls, sharing an unbroken fourth wicket stand of 73 with Callum MacLeod, who hit five boundaries in a run-a-ball 29.
The win was secured with 4.3 overs remaining to emphatically clinch the title.
Adrian Neill pipped Watt, Berrington and Evans to the Man of the Match accolade, and he told Cricket Scotland afterwards: “We started really well in the field. Ali (Evans)and Saf (Sharif) at the top put pressure on and didn’t concede any boundaries.
"The four wickets in the power play is the key for all T20 games – that’s initially what started it off and created a big buzz in the field. I had a couple of butterflies this morning, I was a bit nervous and quite quiet on the bus. On your debut you always hope it goes well. It’s nice when you get early wickets and all the pressure and nerves disappear.”
The teams meet again this week in a three-game 50-over series, with the first game on Tuesday.
