On a slow-churning Day 4 of the first Test against Sri Lanka in Chattogram, Bangladesh removed two wickets after taking a first innings lead of 68 runs. At the close of play on Wednesday, the visitors were 39/2 in 17.1 overs with Taijul Islam on the spell. Sri Lanka captain Dimuth Karunaratne was unbeaten on 18 having faced 45 testing deliveries on a top that has already started producing variable bounce and turn. And they still trail by 29 runs.
