Their wicket included big hitters like Evin Lewis (12) and Shai Hope (9), both West Indies. Another fast bowler Shohidul Islam dismissed Khula Tigers captain Anamul Haq for 9 runs.
But the local boys eventually led Khulna to victory in the first match of the BPL.
Shohidul, who took two wickets, was also the top scorer for Chattogram, scoring 40 runs in 31 balls with the help of four fours and a six. His innings were important in taking the team beyond 100 after seven wickets fell for 80 runs.
Only two other Chattogram batsmen could reach double figures, with Najibullah Zadran scoring 24 and Tanzeed Hasan Tamim scoring 19.
