Nepal climbed one spot up in the ICC World Cup League 2 standings with a convincing seven-wicket victory over leaders Oman on Tuesday after openers Kushal Bhurtel and Aasif Sheikh's century partnership coupled with pacer Karan KC's five-wicket haul in the US Triangular Series.

Invited to bowl first, Nepal bundled out Oman for 163 runs in 46.5 overs at the flat pitch of the Moosa cricket ground in Pearland, Houston. In the run chase, the openers cracked half centuries each and also stitched Nepal's first century partnership for the opening wicket in One-Day International (ODI) as they made 167-3 in 33.1 overs with a winning boundary from Dipendra Singh Airee.

The first win after the third match of the US Series lifted Nepal one spot ahead to fifth in the seven-team standings. Nepal have 15 points from as many matches while Oman, who played their 36th match, the last game of the Series, occupy top position with 44 points. The US are fourth with 21 points from 23 matches.

Nepal and the US will play their last match of the Series on Wednesday. The match is scheduled to kick off at 10:30am local time (21:45 NST).

Nepal had lost to the same opponents by 13 runs in the Series opener on Thursday before sharing points against hosts US on Saturday following a last-ball tie.

Sheikh smashed 62 runs and Bhurtel scored 56 runs before the duo shared a 114-run stand for the opening wicket, the highest first-wicket partnership for Nepal in ODI. It was also the second highest partnership overall for Nepal following Dipendra Singh Airee and Dev Khanal's 129-run stand for the third wicket against Papua New Guinea (PNG) in March.

Bhurtel, the first wicket to fall, cracked five fences in his 75-ball knock before being caught at mid-wicket by captain Zeeshan Maqsood in a delivery by Fayyaz Butt. It was his second successive half century after scoring 61 runs against the US on Saturday.

Sheikh contributed 62-ball 86 that included seven fences and a maximum. He was caught at deep square leg by Khan in Butt's delivery.

Dev Khanal was out on 10 runs as he was trapped leg before by Khawal Ali. Rohit Paudel remained unbeaten on 26 runs off 21 comprising a boundary and a six each. Airee was unbeaten on six runs.

Earlier, electing to bat first, Oman lost wickets at a quick succession. They were 5-49 before captain Maqsood, who had also scored a century against Nepal in the first game of the Series on Thursday, came to their rescue with a half century.

Coming at number four, Maqsood contributed 52 runs off 100 deliveries and also shared an 83-run stand for the sixth wicket with Sandeep Goud. The skipper hit three and was trapped leg before by all-rounder Dipendra Singh Airee in the 42nd over.

Goud scored 47 runs in his patience knock off 91 balls that included three boundaries and a maximum. He was caught by captain Sandeep Lamichhane at mid-wicket in a delivery by medium pacer KC.

Opener Jatinder Singh contributed 26-ball 23 while Naseem Khushi (10) and Fayyaz Butt (not out 13) were the other Oman batters to touch double digit figures.

Medium pacer KC was the most successful bowler for Nepal claiming second five-wickets in a row against Oman. He conceded 33 runs in his nine overs. Captain Lamichhane grabbed three wickets in his 10-over spell giving away 47 runs. Sompal Kami and Airee picked one wicket each.
