West Indies Women 223 for 6 (Taylor 85, Quintyne 41) beat England Women 181 (Beaumont 57, Winfield 51, Taylor 3-29) by 42 runs
The batting frailties that have dogged England's women throughout their tour of the Caribbean resurfaced with a vengeance once again in the fourth ODI at Sabina Park, as West Indies squared the five-match series at 2-2 with the decider to come at the same venue on Wednesday.
Chasing 224 to win after Stafanie Taylor's 85 from 129 balls had laid a strong total for the hosts, England appeared to be well placed on 133 for 1 in the 29th over. However, they lost their next nine wickets for 48 runs in 16 overs, five of them to run-outs, to slump to defeat by 42 runs.
However, Beaumont was caught and bowled for 57 by Taylor to inject a hint of anxiety, and when Winfield followed nine overs later, run out for 51, England's momentum shuddered to a halt.
Nat Sciver departed six balls later to become Taylor's second victim, and before the over was out, England had lost their third wicket for four runs in the space of 10 balls.
After a brief rally through Heather Knight and Georgia Elwiss, the second wave of England's collapse was even more dramatic - four wickets for four runs in 19 balls - with Taylor's second caught-and-bowled accounting for Knight for 36 and ending England's meagre hopes.
Hayley Matthews chipped in with two wickets to account for Amy Jones and Jenny Gunn, and fittingly it was left to Taylor to wrap up an astounding allround performance with her second run-out of the innings to remove Laura Marsh for 13.
Earlier Taylor's innings of 85 had featured six fours and two sixes, and included a second-wicket stand of 69 with Shaquana Quintyne, who made 41.
