BASSETERRE, St Kitts (CMC) – Amir Jangoo turned a childhood fantasy into reality by scoring a One Day International century on debut and West Indies pulled off another record chase to defeat Bangladesh by four wickets and complete a series sweep here at Warner Park on Thursday.

The 27-year-old Jangoo gave himself the perfect Christmas gift, scoring an unbeaten 104 while Keacy Carty blasted 95 and the West Indies chased down Bangladesh’s imposing 321 for five, finishing on 325 for six off 45.5 overs to comprehensively claim the series 3-0.

Jangoo became just the second West Indian since Desmond Haynes in 1978 to score an ODI century on debut and his knock helped West Indies record the highest successful run chase at Warner Park.

A West Indian victory seemed unlikely after they had slumped to 31 for three early on.

Brandon King ran himself out for 15 when he was turned back by his opening partner Alick Athanaze attempting a suicidal run, Athanze was clean bowled for seven attempting a sweep shot off a full delivery from left-arm spinner Nasum Ahmed and captain Shai Hope nicked pacer Hasan Mahmud to second slip after scoring just three to put the visitors in control.

The in-form Sherfane Rutherford joined Keacy Carty, and the pair added 55 runs in 10 overs to repair the innings.

But just when he was looking to accelerate, Rutherford pulled a short delivery from fast bowler Taskin Ahmed straight into the hands of Tanzid Hasan at deep square leg to be out for 30 from 33 balls.

His demise brought Player-of-the-Match Jangoo to the crease, and the left-handed Trinidadian was fortunate to get off the mark as he scampered an ill-advised single, as he would have been out had Jaker Ali’s throw from extra cover hit the stumps.

The pair then shared a 132-run stand for the fourth wicket to bring the home side back into the contest.

Carty smashed Rishad Hossain for back-to-back boundaries to start the 18th over before turning his attention to offspinner Mehidy Hasan Miraz, hitting him for a six and a four off consecutive deliveries to bring up his fifth ODI half century off 48 balls.

Jangoo started a bit slowly, but scored his first boundary when he drove Nasum Ahmed to the cover boundary.

That instilled some confidence, and he struck the same bowler for two more boundaries in his next over as West Indies moved to 165 for four after 26 overs.

Jangoo then reached his 50 off 45 balls when he scampered two runs after driving Miraz to long off.

He was lucky not to be dismissed on 61, but substitute fielder Emon dropped a regulation catch running back from mid off.

It was an opportunity Bangladesh would regret.

Carty looked well on his way to recording his second ODI century, but he was denied when Soumya Sarkar took a brilliant catch at backward point off the bowling of Rishad Hossain, with him five runs short, to leave the score 218 for five.

In all, Carty faced 88 balls and struck two sixes and 10 fours.

Roston Chase made just 12 before Rishad Hossain held on to a stunning return catch and with the score 234 for six in the 38th over, the game was still very much in the balance.

But Jangoo together with Gudakesh Motie brought the Windies home in an unbroken 91-run partnership in just eight overs.

Jangoo moved into the 90s with a boundary off Taskin Ahmed and he brought up his milestone with a crunching six off Afif Hossain.

He then turned to his colleagues and raised his bat, before kneeling to kiss the surface.

The match was over soon after, with Motie providing the finishing touches by hitting Rishad Hossain for two massive sixes.

Jangoo faced 83 balls and struck four sixes and six fours, while Motie finished unbeaten on 44 from 31 balls with three sixes and three fours.

Earlier, Bangladesh posted a highly competitive total thanks to half centuries by Mahmudullah, Miraz, Sarkar and Ali.

Mahmudullah topscored with an unbeaten 84 from 63 balls, Miraz made 77, Sarkar 73 and Ali finished not out on 62.

Their innings helped Bangladesh recover from nine for two after Alzarri Joseph struck twice in the third over by removing Tanzid Hasan and the struggling Litton Das, both for ducks.
