Sharjah - Afghanistan defeated Zimbabwe by five runs in a thrilling Twenty20 clash on Friday to follow their triumph in the one-day series.
Chasing 188 to win, Zimbabwe fell just short when Luke Jongwe, needing a six to win, was dismissed off the last ball of the match.
It was a controversial finish, however, after Afghanistan seamer Dawlat Zadran was allowed to keep bowling the final over despite having sent down two waist-high full tosses.
Jongwe was caught by Gulbadin Naib out in the deep to leave Zimbabwe on 182/7 in their 20 overs.
Malcolm Waller was the not out batsman on 49 with two sixes and two boundaries off 37 balls.
Zadran finished with 3-32 off his four overs.
Afghanistan had won the toss and chose to bat, making 187/7 in their 20 overs.
Usman Ghani top-scored with 42 off 38 balls with a six and five boundaries while man-of-the-match Naib made 37 and Mohammad Shahzad, 33.
Veteran off-spinner Graeme Cremer returned impressive figures of 3-17.
The second and final match takes place at the same venue on Sunday.
