Taylor moved up to ninth in the women's batting list, while holding on to fourth place in the allrounder rankings, after she helped West Indies to a six-wicket victory against Ireland in Harare. Matthews, meanwhile, climbed to joint-eighth in the allrounder rankings.
Taylor contributed with both bat and ball during West Indies' win last week, taking the crucial wicket of Eimear Richardson on her way to finishing with 2 for 15, before scoring an unbeaten 54-ball 41 to steer a chase of 160. That performance took her to 676 ranking points in the batting list, and to 319 points in the allrounder table, behind only Marizanne Kapp (384), Natalie Sciver (372) and Ellyse Perry (365).
In that same game, Matthews chipped in with figures of 10-3-20-2, removing Ireland captain Laura Delany and Orla Prendergast in a single over. She came out of the game with a career-best 272 ranking points in the allrounder list, joining joining Katherine Brunt and Jess Jonassen in a three-way tie at eighth.
