Opener Liton Das top-scored with 35 as Bangladesh defeated Afghanistan by six wickets in the second Twenty20 international to take the two-match series 2-0 on Sunday. Liton laid the foundation for the win with a 67-run opening stand with Afif Hossain (24) as Bangladesh raced to 119-4 in 16.1 overs after Taskin Ahmed's 3-33 helped the side restrict Afghanistan to 116-7 in a rain-reduced 17 overs. Bangladesh won the opening match of the series by two wickets on Friday, and Sunday's follow-up -- both of them in the northeastern city of Sylhet -- earned them their third consecutive T20 series win, and their first against Afghanistan in three attempts.
