The flamboyant middle-order southpaw, who replaces hard-hitter Yuvraj Singh, was well aware that he would have to perform in the tournament to prove his mettle and cement his place in the national squad.
"Obviously, there will be pressure on me and I am confident I will not disappoint the selectors, who have put faith in me", he said.
Tiwary, the second player in the national squad from Jharkhand after India captain M S Dhoni.
Tiwary, Jharkhand Ranji captain, said his consistent performance in IPL-III drew the attention of the selectors, and added that he was also expecting a call for the tri-series held in Zimbabwe recently on the basis of his IPL performance.
Tiwary scored 419 runs for the Mumbai Indians in the last edition of IPL. Replying to a poser, Tiwary said state-mate Dhoni is "a great cricketer" and he did not wish to be compared to him.
Earlier, Tiwary, accompanied by JSCA president Amitabh Choudhury, arrived at Keenan Stadium late in the evening.
Speaking on the occasion, Choudhury expressed confidence that Tiwary would earn laurels for the state as well as the country like Dhoni.
Later, Tiwary visited Tata Main Hospital to meet his friend, who sustained an injury in a road accident near Chandil.
