Dismissed by Tigers pacers Mashrafe Bin Mortaza and Shahadat Hossain respectively in the two innings of the Chittagong Test before opening his account, the 29-year-old made his fourth Test century in the second and final match in Dhaka under extreme conditions with heat and humidity taking their tolls.

Floored on 40 by left-arm spinner Mohammad Rafique off his own bowling in the second ball after lunch, the right-hander concentrated hard to bat fluently to reach the three-figure mark with a boundary on the onside.

Like his opening partner Dinesh Karthik, the Mumbai batsman succumbed to dehydration midway through the final session and sought the cool of the dressing room.

The feat, in his 19th Test, also made him only the third player in history of Test cricket to sandwich a pair with centuries in consecutive matches.

Jaffer had scored 116 against South Africa in Cape Town before the Chittagong ducks.

His compatriot and now Indian chief selector Dilip Vengsarkar scored 157 not out against West Indies in Kolkata in the 1978-79 home series, following it with a pair in Chennai and a 109 in Delhi.

Late West Indian batsman Clifford Roach did the same at home against England when he made 122 at Bridgetown, followed by two zeroes at Port of Spain and 209 at Georgetown.

Apart from Jaffer and Vengsarkar, fellow Indians Yashpal Sharma and Mohinder Amarnath are also in the 15-member list of batsmen to score hundred after a pair.

The last man before Jaffer do it was Chamara Silva, the Sri Lankan who got a pair on debut and made 61 and 152 not out in the next Test in New Zealand in December 2006.

Expectedly, a tired but smiling Jaffer mentioned that getting a hundred in Test cricket is always pleasing.

"It's nice to come back after a pair and get a 100. I'm always determined no matter what the result is. But obviously I was double determined after a pair," Jaffer told at the post-match conference on Day One.

When asked about local conditions during this time of year, Jaffer said that it was something beyond his control.

"I mean playing and not playing is not in my hands. The two boards are to decide to keep the matches. But obviously the condition is tough. As you know you can see that both Dinesh and I came with cramps and dizziness. The conditions will be tough for both the teams."

He admitted that there had been some pressure coming to the Dhaka game.

"Getting a pair is obviously not a very good feeling. I was determined to have a good score and I'm really happy. I'm also delighted that I'm playing. If I didn't play I wouldn't have got this score. Thanks to the committee for selecting and giving me a chance," said Jaffer, who now has two century-stands with Karthik.

"We have been doing the opening for the last three Tests and twice, in Cape Town and here, we've got 100 partnerships. We are really good friends. So that helps in having a good partnership.

Jaffer, the only specialist opener in the Test squad in absence of out-of-form Virender Sehwag, said manager Ravi Shastri's advices had also been a great help.

"It was more mental that physically. He was just telling me to be more positive in the mind and told not to worry about the pair because it happens to everybody," added Jaffer who was really surprised to be invited to bat on the surface.

"They (Bangladesh) obviously tried their best but things did not happen because the wicket did not support them."
