NEW DELHI, MARCH 10: The attitude and positive approach of the India under-19 players, who have clinched the four-match one-day series against the visiting Sri Lankans 3-0, came in for praise from coach Krishnamachari Srikkanth. ``They have the will to perform and win every match. That is the right spirit to play positive cricket,'' he said.India is keen to make a clean sweep of the series. ``We'll go all out to win the final game tomorrow. We won't relax although we have won all three games with convincing margins,'' an elated Srikkanth said.In the final encounter tomorrow, the Sri Lankans will be handicapped by the absence of skipper Upeka Fernando (among Sri Lanka's World Cup probables), who sustained a hairline fracture on his ankle, and leg-spinner Malinga Bandara who tore a webbing of his right hand.
