Australian leg-spinner Alana King claimed a crucial 2-17 as Trent Rockets began their Hundred campaign in fine style with a 20-run victory over Northern Superchargers at Headingley.

Chasing 124 on a dry surface, last year's runners-up were dismissed for 103 in 97 balls, with King leading the attack.

Lucy Higham top scored with 26 for the Superchargers, as King - in combination with fellow spinners Kirstie Gordon and Aussie Ash Gardner - turned the screw.

A third Australian, seamer Heather Graham, also impressed with 3-13. Gardner chipped in with 1-18.

"It was nice to have a bit of turn and grip in the wicket," said King, who was player of the match.

"We saw that the wicket did a lot in the first innings so we just had to keep our processes really simple. I love to have a pitch with a little bit of turn and I was happy to play my part."

"It felt really nice out of the hand," King said of the delivery which bowled wicketkeeper Bess Heath. "It's a leg-spinner's dream, so I'll take that first pill.

"I've loved having Ash (Gardner) and HG (Graham) join the Rockets this year. We played three Aussies today and we loved getting the win."
