Dhaka: Bangladesh cricket authorities on Tuesday sought an explanation from their Sri Lankan curator Gamini de Silva for preparing a slow wicket in Dhaka, where the hosts lost the tri-nation final against Sri Lanka.

The islanders defeated much-fancied Bangladesh by 79 runs on Saturday to win the 50-over tournament, which also involved Zimbabwe.

Bangladesh were bowled out for 142 while chasing 222 at the Sher-e-Bangla National Stadium, where they had posted 320-7 in the league phase against the same opponents.

“We wanted to know from Gamini why the wicket behaved like that,” said Bangladesh Cricket Board media committee chairman Jalal Younus.

“It was a wicket of 320 runs. All of a sudden, it turned out to be a slow wicket. This is a routine explanation, which we can always seek from an employee,” he said.

Officials said the slow wicket was contrary to the requirements of the home team with experts identifying it as one of the main reasons behind the hosts’ debacle in the final.

Umpire-turned-curator De Silva has been in charge of the Sher-e-Bangla National Stadium since 2011. He also came in for some harsh criticism for producing slow wickets during the Bangladesh Premier League Twenty20 tournament in November.

The ground also came under scrutiny from the International Cricket Council, which rated its outfield as “poor” after Bangladesh beat Australia in a Test match in August-September.
