The Sri Lankan team may be a second string side, but they had performed better than expected during the ODI series. The first match was a one sided affair, but the second match was a close one and Sri Lanka could have won it had the luck gone their way. And the most encouraging sign for Sri Lanka is that they have discovered a couple of young players, who could become regulars in the fist choice XI.
Now coming to the T20 series, I believe that Sri Lanka has a very good chance of staging an upset in at least one of the three matches. If the gambling sites continue to give odds of 5.50-6.00 to them, then those who bet in favor of SL will get good returns even if they lose two of the matches and win at least one. I have a feeling that the T20 series is going to be more evenly contested.
