Travelled with the team but not considered in the last five ODIs, the 24-year-old Rajin came out with his trusty bat to smash a dazzling 108 as Bangladesh recovered from an all too familiar top-order collapse to cruise to 237-3, chasing a fighting Kenya total of 232, with 8.3 overs to spare.

Rajin's signature performance in his 34th ODI made him only the third Bangladeshi batsman to score a century after former national opener Mehrab Hossain (101) and Mohammad Ashraful (100).

Along the way the pocket-side right-hander also featured in a record 175-run partnership for any wicket with captain Habibul Bashar, who played the best supporting actor's role with a superb unbeaten 64. Their fourth wicket stand surpassed the previous mark of 170 for the first wicket between Shahriar Hossain and Mehrab Hossain which was done on the same day in the 1999 tri-nation Meril Cup against Zimbabwe.

However it did not look so easy after Bangladesh were reduced to 62-3, with Shahriar Nafees (20), Mohammad Ashraful (11) and Aftab Ahmed (9) already back in the dressing room.

But in a series of records, the home side reserved their best for the last with Rajin and Bashar showing the maturity that one can expect of a Test playing nation.

Rajin, whose previous best was 82 against India in December 2004, played every shot almost to perfection in his 113-ball knock that featured 16 glorious boundaries. He reached the magical three-figure mark with a sweetly timed four to the mid-wicket boundary off paceman Toni Suji amidst applause from a capacity 16,000 crowd at the fourth purpose-built cricket venue of the country.

The only blemish of Rajin's innings was when he missed an attempted lofted drive against Kenyan captain Steve Tikolo at 40. But wicketkeeper Morris Ouma, who had a miserable day behind the stumps, also missed the chance to effect an easy stumping.

Bashar on the other hand lived up to his growing reputation as a motivator when the chips are down. The Bangladesh captain, who was involved in that magnificent fourth wicket stand with Ashraful against Australia in Cardiff last year, once again played the role of a senior statesman. His ninth fifty, though after a fairly long time, contained five boundaries.

He also finished the chase in style, hitting the third ball of Kenya's find of the series Tanmay Mishra, straight in front of the site screen for a six.

Earlier, Steve Tikolo hit a captain's knock of 81 off 87 balls to help his struggling side to post their highest total in the series. Tikolo, a familiar figure in Dhaka cricket, struck nine fours and a six before being adjudged leg before off left-arm spinner Mohammad Rafique.

Collins Obuya, coming into bat at number five, struck a quick-fire 45 and left-handed Hitesh Modi chipped in with 35.

The bowling of the visitors that lacked the bite and penetration throughout the series once again let them down.

Bangladesh's left-handed opener Shahriar Nafees was adjudged man-of-the-series with 196 runs that included two fifties.

Rajin won the man-of-the-match award for a knock cricket fans will remember in the years to come.

Kenya, who came here with an impressive 6-1 record, will take a long flight back home today with their image seriously dented by a vastly improved Tigers, whose 4-0 series triumph could be considered as a boost ahead of the biggest challenge against mighty Australia, who will arrive in Dhaka on April 6 for two Tests and three ODIs.
