Kingston (Jamaica): Hanuma Vihari has credited his success in the second Test against the West Indies here to Ravi Shastri, saying the India head coach's advice not to stay upright but flex the knee while batting helped him notch up his maiden century.

Vihari (53 not out and 111) was adjudged the Man-of-the-match in India's 257-run win over the hosts in the second Test on Monday (September 2).

Asked what did Shastri tell him after his first innings, Vihari said: “He (Shastri) was talking about flexing my knees a little bit, I was a little upright in the first innings, so flexing my knees meant I could move my foot both on front and back foot.”

"It worked out very well and a lot of credit should go to him," Vihari told India fielding coach R Sridhar during an interview, the video of which was posted by BCCI on its website.

The 25-year-old emerged as India's top run-getter against the West Indies in the two-match Test series with 289 runs.

"I relish batting under pressure because that is the challenge you have to accept as a batsman and these situations brings the best out of me," said the Andhra batsman, who had scored a 93 in the first Test in North Sound.

"I feel I try to focus on what the situation is, and have a certain game plan and I was fortunate enough to have good partnerships with Jinx (Ajinkya Rahane). He batted beautifully as well."

Vihari said he was confident of a good outing during the two-match Test series against the West Indies as he had spent enough time on these pitches during the last two months with the India A team.

"I was in really good space. I have been in Caribbean for last two months, I have been practicing and playing matches on this wicket," he said.

"So I was really confident and I think I played well in the practice match and it gave me that extra boost. I was looking forward to this series and I am happy it went well." 

In his first year in international cricket, Vihari has played six Tests but he seemed to have lost a bit of hair, got married and has also scored 6,000 plus first class runs despite being just 25 years of age.

"I started my first-class cricket quite early and that's why I could score 6,000 runs. I don't know about the hair, may be too much batting from childhood," he said with a laugh.

"... That experience will count, batting for nine years in first class cricket, and it helped me in pressure situation.”
