India finished the fourth day of the second Test against Sri Lanka here Thursday with a lead of 27 runs at 669 for 9 wickets. The match is now heading for a certain draw with a seemingly meaningless last day Friday. The day's highlight was Suresh Raina's Test century in his first ever match. He became the 12th Indian to score a century on debut and the first since Virender Sehwag's similar feat against South Africa in 2001. 'Not always you get a chance like this and by the grace of god I was able to do it,' Raina said. The boundary scored by Raina to reach his hundred was a double celebration for India as it took India past the 442 to make Sri Lanka bat again. His hundred came off 192 balls with two sixes and ten fours. The Indian master batsman Sachin Tendulkar scored his fifth double hundred of his career off 338 balls faced with 23 fours and one six. The Tendulkar-Raina partnership added 256 runs which steered India to safety. Sri Lankan attack clearly missed the penetration of Muttiah Muralitharan and Lasith Malinga. The part time bowler T. M. Dilshan chipped in with two wickets in one over to dismiss Tendulkar for 203 and Harbhajan Singh to finish with flattering 3 for 50. Ajantha Mendis who was expected to trouble the Indians finished the day with 4 for 157 off 54 overs. His partner Suraj Randiv went for over 200 runs for his two wickets. India lost to Sri Lanka in the first Test held last week in Sri Lanka's southern port town of Galle.
