Viv Richards, unsurprisingly, tops this list. He is pretty much the Bradman of ODI cricket - unparalleled in his achievements. On top of that, he is actually also an all-rounder (his Bowling IMPACT also comfortably crosses 1). His tally of 9 SDs (series or tournament-defining performances) is also the fifth highest in the history of ODI cricket. Interestingly, 6 came purely for his batting, 3 as an all-rounder. Moreover, West Indies never lost a series under his captaincy and as a result he is also the second-highest impact captain for West Indies after Clive Lloyd.
The most surprising name on the list for many is that of Carl Hooper's - number 2 here. Being under the shadow of Brian Lara camouflaged his remarkable impact - his all-round consistency (with a very low failure rate of 29%, given the span of 227 matches), those seemingly innocuous off-breaks, his sharp slip fielding (his Fielding IMPACT is the second-highest amongst West Indians) and reasonably decent Captaincy IMPACT - all adding up to a giant - unsung till now.
All the West Indian bowling greats also make this list at quite a high position, namely Michael Holding, Joel Garner, Curtly Ambrose, Courtney Walsh, Malcolm Marshall and Ian Bishop. If the cut-off is reduced to 50 matches, Andy Roberts makes up the missing block of the famed quartet in this chart.
Jeff Dujon and Ridley Jacobs are the two wicket-keepers who make this list; surprisingly none of them have a Batting IMPACT of even 1. Nevertheless both of them have 1 SD each - not at all a common thing amongst wicket-keepers (except Adam Gilchrist and MS Dhoni).
These are the highest impact ODI batsmen in West Indies' history:
Perhaps the only big surprise here would be the presence of the West Indian opener Sherwin Campbell right at the end of this list - his relative consistency and singular SD getting him through here.
