Off-spinner Anisa Mohammed recaptured top form yesterday and wrecked South Africa's batting with a five-wicket haul that propelled West Indies to a series-winning 13-run victory in their second Twenty20 Women's International.

Mohammed's career-best effort triggered a monumental South African collapse to 101 all out in 19.2 overs, the home side stunningly losing their 10 wickets for just 28 runs after the West Indies had scored 114 for nine off their 20 overs at Newlands.

Scores: WEST INDIES 114-9 off 20 overs (Cordel Jack 41; Ashlyn Kilowan 2-16, Alicia Smith 2-23); SOUTH AFRICA 101 off 20 overs (Shandre Fritz 42, Trisha Chetty 31; Anisa Mohammed 5-10, Shemaine Campbelle 2-19).

The result complemented the six-wicket victory the West Indies had in Sunday's opening match and gave them a winning 2-0 lead in the three-match series.

Sent to bat, West Indies lost openers Deandra Dottin (12) and Stafanie Taylor (14) cheaply and slipped to 33 for two in the fifth over.

Veteran Cordel Jack bolstered the Caribbean side's innings with a well-played 41, the Vincentian right-hander smashing five boundaries in a 43-ball innings that prevented a collapse of the innings. Stacy-Ann King (10) was the only other West Indian getting to double figures.

The South Africans, who had won the preceding one-day inter-national series 2-1, appeared to be coasting to victory when openers Shandre Fritz, with a top score of 42 off 35 balls, and Trisha Chetty (31) posted a 73-run first-wicket stand in 11.3 overs.
