Marvan Atapattu, his opening partner, however, was not going to miss out on the big opportunity that the match provided. The classy batsman put his best foot forward while carving out his first one-day international hundred in 18 months. His 101 off 118 balls, which contained eight boundaries, was his fifth ODI hundred in all, and ensured that the opener found some much-needed form ahead of Sri Lanka's likely semi-final clash against world champions Australia.
