Draw would be great for Sri Lanka, but I really doubt whether they'll be able to do it. Right now Bangladesh is at a very comfortable position, at 474/4. They should be able to reach somewhere around 550-600 before the end of first session today, which means that Sri Lanka needs to score 350-400 to start with, in order to avoid follow on. But here the catch is that Bangladesh is missing some of the most experienced bowlers. So can they limit Sri Lanka to less than 350-400 in the first innings? And if they are able to do that, should they ask Sri Lanka to follow on?
