Pace bowler Fareed Ahmad kept cool in the last over on Friday to foil Asif Khan's aggressive hitting as a depleted Afghanistan beat the United Arab Emirates by four runs in a tri-series match.
After Asif opened the final over with a four, a six and a two, Ahmad beat the bat with the next two balls. Asif needed to find the boundary off the last ball but was caught as Afghanistan held on to win at the Sharjah stadium.
Afghanistan, already sure of facing Pakistan in Saturday's final, rested six of their main players, including skipper Rashid Khan, veteran Mohammad Nabi and in-form opener Sediqullah Atal.
Afghanistan made 170 for four before restricting the UAE to 166 for five in their 20 overs.
Afghanistan's stand-in skipper Ibrahim Zadran won the toss and batted.
With Rahmanullah Gurbaz, Zadran put on 98 for the first wicket in 12 overs.
Zadran hit 48 in a 35-ball knock that contained three sixes and as many fours.
Gurbaz smashed three fours and a six in his 38-ball innings before both the openers fell off successive deliveries.
Kariam Janat made a 14-ball 28 with three sixes and a boundary, and Gulbadin Naib scored a 13-ball 20 not out as Afghanistan hit 56 runs in the last five overs.
Left-arm spinner Haider Ali was the best UAE bowler with 2-23.
For the hosts, Muhammad Waseem scored a 29-ball 44 with three sixes and two fours, while Asif made a valiant 28-ball 40 with two sixes and four fours.
