JOHANNESBURG, South Africa – An electrifying career-best hundred from Deandra Dottin proved futile as rain had the final say, forcing a no-result in the opening One-Day International against South Africa Women on Friday.Sent in at the Wanderers, West Indies Women rallied to 234 for three in the 46th over, behind Dottin’ marvellous unbeaten 150, before the second of two rain breaks forced a premature end to the innings.Hayley Matthews stroked a classy 51 from 63 deliveries, combining with Dottin in a 186-run, third wicket stand that rescued the tourists from the peril of 27 for two in the 10th over.Set a revised 204 from 29 overs under Duckworth-Lewis-Stern, the hosts were stumbling on 87 for five in the 18th over when the rains returned for the third time in the encounter, this time ending it for good.South Africa Women were well placed at 41 for one at one stage but off-spinners Karishma Ramharack (2-18) and Hayley Matthews (2-27) snatched two wickets apiece to give West Indies Women the edge in the contest.
