India could have expended more wickets, but I'm not sure if they would have gotten many more runs. Once Sri Lanka started bowling properly, they were harder to score off. Conditions are similar to the last game, where England scraped to 150. I can't imagine why Sri Lanka would merely aim to score 140 and hope that is enough; they'll be looking for a win, so India remain in a good position and it's up to Sri Lanka to take it off them.
