Leg-spinner Vipraj Nigam comes into the attack, to bowl the fourth over. Rickelton taps the first ball into the leg side for a single and Jacks pulls the third ball over midwicket for a four followed by a dot ball.
He defends the fourth ball and does the same next ball as the leggie gets some turn.
Nigam also bowls a half-tracker as Jacks pulls it past midwicket for the second four of the over.
Mustafizur continues as Rickelton defends the first ball and taps the next into the off-side for a single.
Jacks makes room and tries to hit the pacer through the off-side but can't connect as the pacer beats him with a clever change of pace.
Jacks nearly done in with the slower ball. He looks to flick the pacer across the line but is too early into the shot as he gets the leading edge which flies over point for a four.
Mustafizur too predictable with his change of pace. This time Jacks is waiting for the slower ball, pitched on the pads, as he plays a cracking pick up shot over square leg for a six.
