KARACHI, Pakistan – Nicholas Pooran’s career-best fifty pushed West Indies to a 200-plus total for only the third time in three years but Mohammed Rizwan and captain Babar Azam registered equally destructive half-centuries of their own, as Pakistan pulled off a record run chase to make a clean sweep of the three-match Twenty20 International series here Thursday.Choosing to bat first at the National Stadium here, West Indies raced to 207 for three off their 20 overs with the left-handed Pooran sparkling with 64 off 37 deliveries – his fourth half-century in T20 Internationals.
