Sri Lanka and England cannot be split apart as the second test begins in Colombo according to Ladbrokes.
Play gets under way on Tuesday with both teams chalked up at 15/8 for victory, however nothing less than a win will be good enough for Andy Flower's men if the wish to remain the world number one Test side.
Sri Lanka (2/5) are favoured to wrap up the series and the draw can be backed at 2/1. The firm will also refund losing match bets if Andrew Strauss hits a ton during the 1st innings.
Jessica Bridge of Ladbrokes said: "All the money and all the pressure is on England at the moment. Patriotic punters are piling in to England after last week's dramatic ending."
