Set a challenging target after Usman Khawaja’s 98 and supporting half-centuries from skipper Steve Smith (74) and George Bailey (55) lifted the visitors to 265 for seven batting first, the enigmatic Samuels stroked 92 to ensure that the target was reached with 20 deliveries to spare.
“It’s all about delivering for the team and keeping us in contention in the competition,” Man of the Match Samuels said.
With a previous best of 63 from 27 ODIs against the most dominant team in this form of the game, the Jamaican right-hander made an important deposit on a significant overdraft against the World Cup-holders, his innings spanning 87 deliveries and decorated with eight fours and four sixes --the last three of which came off consecutive balls from leg-spinner Adam Zampa over long-off.
In keeping with his mercurial nature, he was run out off the very next delivery to have the West Indies at 240 for four in the 41st over. Two more wickets fell to Nathan Coulter-Nile with the score at 254 before Kieron Pollard and Carlos Brathwaite formalised victory in the 46th over.
Denesh Ramdin also played a key role in the run-chase. He supported Samuels in a 73-run fourth-wicket stand and continued to play sensibly following the demise of his senior partner before being bowled by Coulter-Nile for 29.
Victory pulled the West Indies within a point of leaders Australia in the three-team standings. West Indies next play South Africa on Wednesday at the same venue.
Samuels had joined Darren Bravo at the crease following a rollicking opening stand of 74 in ten overs from Johnson Charles and Andre Fletcher.
Bravo and Samuels then steadied the West Indies chase, keeping them well on course in an 82-run third-wicket partnership that was broken when Zampa was summoned back into the attack and removed Bravo for 39 via at bat-pad catch that lobbed comfortably to wicketkeeper Matthew Wade.
