West Indies ended the tournament sixth on four points from their last two victories over Pakistan Women and Sri Lanka Women, with all three teams along with fifth placed New Zealand Women suffering elimination.
West Indies, though, never really looked like closing in on their modest victory target after struggling to 73 for four, captain Stafanie Taylor out for a 12-ball duck.
However, 23 wickets at 16.17 in the Regional 4-Day Tournament has convinced the selectors Roach deserves another chance in three Tests, including the first day/night red-ball worldwide, in England. The dream final for the organisers would see England take on Australia, though South Africa and India - Australia's opponents in Derby on Thursday - will do their utmost to spoil that.
Beaumont put on 47 off 56 deliveries for the first wicket with Lauren Winfield who made 11 before picking out Matthews on the mid-wicket boundary with rookie left-arm seamer Akeira Peters.
Wicketkeeper Sarah Taylor was dismissed for nought, the second wicket to fall after sending a thick edge off Deandra Dottin to Hayley Matthews with only 54 on the scoreboard.
Opener Tammy Beaumont top-scored with 148 and will once again be the key for England.
Leg-spinner Afy Fletcher sends down a delivery during her impressive 10-over spell against England Women on Saturday.
The lbw calls continued to come, and all-rounder Sciver clinched her third wicket in three overs after Fletcher played all-round her legs.
But once Beaumont scooped a full toss from Fletcher to the wicketkeeper in the 22 over, three wickets fell for 14 runs to leave England stumbling on 105 for five in the 26 over.
Shrubsole ensured the hosts claimed a record seventh lbw in an innings - a first in women's one-day international's - as West Indies trudged to an incredibly slow 128-9 off their 50 overs.
"It's going to be really important seeing that we won the last two. Throughout the tournament we have managed to find our way out of sticky situations".
"Once you get into the semi-final there's no "this is a more superior team" or "this is the inferior team"‚" Luus said. "In that sense, I'm very proud of the girls, it's our first semi-final since 2000", she added.
