Oman clinched two victories in as many games to kick-start their campaign in a dominant fashion, while USA triumphed over Uganda with a spirited display.
Oman made it two wins from two in the opening stages of the ICC World Cricket League Division 3 on an exciting second day of action.
Skipper Zeeshan Maqsood was the star of the show as his side downed Singapore – making its tournament bow – on Saturday.
The captain took 2-18 from his ten overs with the ball and anchored the chase with 43 not out as Oman claimed a four-wicket win to move top of the nascent standings, as it looks to bounce back to Division 2 at the first time of asking.
Meanwhile, Monank Patel hit 107 at the top of the USA order and its total of 252 for six always looked like being beyond a Ugandan side that had beaten Denmark in the first round of games.
Patel was the star of the show as USA, having been put in to bat by Uganda, compiled 252 for six from their 50 overs.
Patel hit 107 from 137 balls to provide the backbone of the USA total but he was given late-order support from Henry Walsh (47 from 55 balls).
USA became the first team of the week to top 250 from its 50 overs and in response, Uganda never looked like getting close.
Arnold Otwani made 52 at the top of the order but no-one could stay with him, Timil Patel ripping out the Uganda top order by taking care of three of its top five.
Deusdedit Muhumuza provided a late innings rally with 43 not out from 58 balls but it finished 54 runs short in the end, albeit with one wicket to spare.
