An unbeaten century from Rameez Shahzad saw UAE gain revenge on Scotland with a four-wicket win in Dubai.
The Saltires were edged out in a high-scoring encounter, with Shahzad finishing not out on 121 as he led the hosts to victory with five balls to spare.
But the victory was not enough to prevent UAE finishing bottom of the tri-nation series, which had already been won by Ireland.
Scotland had claimed a comfortable win over UAE on Sunday – their first of the series – and again opted to bat after winning the toss.
An experimental batting line-up fared well, with Kyle Coetzer making a brisk 75 and Richie Berrington a 95-ball 90.
George Munsey provided some late impetus with 47 as Scotland posted a daunting total of 299 for nine.
They appeared on course for victory after picking up two early wickets, but Ashfaq Ahmed (92) and Shahzad put on 125 for the third wicket to bring UAE back into the game.
Shahzad went from strength to strength, striking 10 boundaries and two sixes, and was ably supported by Adnan Mufti (38) before hitting the winning run off Scott Cameron at the start of the final over to secure a first win in the series for UAE.
Head coach Grant Bradburn told cricketscotland.com: “This series has been a tough challenge against quality opposition and so valuable in many ways.
“We have seen new players take opportunities to show they are very capable at this level. We have also spent valuable time developing plans and combinations for the World Cup qualifier in Zimbabwe.”
Centuries from captain William Porterfield and Andrew Balbirnie helped Ireland beat the UAE for the second time in three days in their Tri-Series match.
Ireland had beaten the same opponents by four wickets on Thursday, and were comprehensive victors by 67 runs in Dubai to make it back-to-back successes in the series, which also features Scotland.
Porterfield hit 139 from 147 balls at the top of the order, adding 201 for the second wicket with Balbirnie, who was out for 102 from 109 deliveries as Ireland posted 301 for five from their 50 overs.
Kevin O’Brien then took four for 41 as the hosts came up well short, eventually being bowled out for 234 despite Rameez Shahzad’s half-century.
Medium pacer Barry McCarthy took 2-49 while Andy McBrine finished with figures of 2-40.
UAE Under-16 skipper Aryan Lakra believes the eight-wicket victory over Oman on Monday will give them a lot of confidence going into the rest of the Asian Cricket Council (ACC) Western Region tournament.
The fixture had been delayed due to rain at Ajman’s Eden Gardens, forcing the game to be reduced from 35 to 23 overs. However, that did not stop the hosts comfortably reach their 102-run target in the 18th over with Ansh Tandon scoring a fluent 49.
The batsmen would have fancied their chances of reaching the target after Chathiya Dashan (1-7), Lakra (1-22) and Yuvraj Jaisingh (1-16) were among the wicket-takers for the UAE as Oman struggled to reach 101-5.
The UAE will again be on the field when they play Maldives at Sharjah on Tuesday. Another win will clinch top spot and a place in the semi-finals and Lakra believes the team will be raring to go after beating Oman.
“It feels great to win the first game and it will give us good momentum going into the upcoming games and hopefully we can carry this through for the rest of the tournament,” said the 14-year-old all-rounder.
“This game wasn’t much of a competition. Oman put on a good show but we were more stronger in all departments. The most important thing is that we won and we want to do it again against Maldives and book our place in the semi-finals.”
Despite the margin of the victory, Lakra says there’s still room for improvement if they want to go all the way and lift the trophy on Friday.
“I’m really happy with how we bowled but there are still some things that we want to improve on in the next game and try and get better.”
