Surrey have re-signed Aaron Finch on a two-year Twenty20 contract, the club have announced.

The big-hitting Australian, who has played for Surrey across the past two northern summers, will return to the Kia Oval for the next two domestic T20 competitions.

Finch has formed one of the most explosive opening partnerships in T20 cricket with England international Jason Roy during his time at the club.

"I'm absolutely thrilled to be back at Surrey," Finch told the club's website. I have enjoyed my time there these past few seasons and am really looking forward to reuniting with the lads and looking forward to a successful summer."

Surrey director of cricket and former England captain Alec Stewart added: "Aaron Finch is one of the leading T20 batsmen in the game and to have secured his services for a further two seasons is great news.

"His opening partnership with Jason Roy is amongst the most destructive in world cricket and he is now very much an integral part of our dressing room."

Finch has been in fine form recently, crunching a bruising 124 against India in an Indore ODI after coming back from injury.

And in a JLT Sheffield Shield so far dominated by talk of contenders for Ashes spot, Finch showed his red-ball credentials with half-centuries in each innings of a home match against the West End Redbacks.

The return to form marked a turn-around of sorts for Finch, who had feared his days in Australia's limited overs team were over after he injured his calf playing with Surrey this winter.

"I thought after the Champions Trophy, getting 68 against England in the last game, I had a real opportunity to cement my spot and go on and get a big hundred and I didn’t do that," Finch recently revealed to cricket.com.au.

"So obviously I thought my position was quite vulnerable, and then to injure my calf playing for Surrey I thought, 'Well that’s going to be my career over, I’m going to miss this Indian (ODI) series and someone else will come and take my spot and play well'.

"Then to do my calf, just twinge it again, the day before the (first India warm-up) game, that was really, really frustrating.

"I thought right then that I've blown it again. So I was really down for quite a while 'cos I just saw my one-day career just slip away, just like that pretty much."
