Over 4: Wicket! U Akmal st Ramdin b Badree 1: Umar Akmal follows his brother out through Badree's delivery
Over 3: Pakistan 8 for 2: Santokie's delivery is causing problems all the time for Pakistan. His use of pace and move to cut across the right hander has limits them to a five in the third started through Hazeez, who doubles his score with a two through square leg, and moves to five with a single.
