Westwood's positive hitting, including eight fours in his 58-ball stay, set the tone before Maddy and Clarke put on an unbroken stand of 47 to see their side home and boost their chances of staying up.
He was brilliantly taken by Smith, who managed to catch theball above his head onthe long-on boundary but keep his balance and stay inside the ropes, giving the impressive Henriques a third wicket.
