The two teams were dead-level with scores of 6-161 after their 20 overs on Sunday, but the Strikers (9-3) proved too good in the super-over, banking their fifth straight victory and joining Brisbane Heat (9-3) at the top of the ladder (18 points).

Wrist spinner Wellington, who captured 3-17 in the Thunder's innings, was entrusted with the responsibility of bowling the super over and she obliged as the Thunder were restricted to 1-6.

Devine then finished it off, taking three balls to notch the seven required off Shabnim Ismail.

She had earlier smashed 88 off 56 deliveries on her way to earning earn her fifth player-of-the-match gong of the season and move past Brisbane's Beth Mooney to the top of the run-scoring leaderboard (593 at 74.12).

The Thunder required 15 off their 20th over bowled by Sarah Coyte and teenager Rachel Trenaman (20no off nine balls) almost pinched it with some wonderful hitting.

But she lost strike for the last ball when, with one required, Coyte speared down a yorker and had Nida Dar adjudged lbw.

Hard-hitting Kiwi Rachel Priest was the early aggressor in the chase, belting 48 off 20 inside the powerplay before falling to a terrific outfield catch from Devine after top-edging a sweep off Wellington, who enjoyed a memorable weekend after also taking 3-23 against Hobart on Saturday.

Naomi Stalenberg (37) and Rachael Haynes (29) kept the Thunder in touch before Trenaman almost powered them over the line at the death.

Earlier, Devine crunched her seventh 50 of a golden campaign and her sixth in her past seven innings to get the Strikers rolling.

Tahlia McGrath (32) put on 69 for the second wicket with Devine after skipper Suzie Bates exited cheaply.

Young Hannah Darlington (3-29) was the chief destroyer for the Thunder, who were valiant but ultimately heartbroken after suffering their sixth successive defeat
