CRICKET: Taking down champion Perth Scorchers would be Alex Carey's ideal parting gift before leaving Adelaide Strikers on Big Bash League finals eve for Australian Twenty20 duty.

Carey, express quick Billy Stanlake and skipper Travis Head are targeting a third BBL minor premiership for Adelaide on Thursday at the WACA and a psychological blow crucial to an inaugural title.

"It will be a tough one in Perth, they are flying. We want to go into the finals with momentum and the guys are very excited about that,” Carey said.

The Strikers lost to Perth in Alice Springs earlier this season but relish a rematch with Justin Langer's second-ranked team ahead of a home semi-final on Friday week at Adelaide Oval.

"We want to beat the best side of the last couple of years. Knocking them off in Perth would give all the players confidence but we have the belief, are a tight group,” Carey said.

The pressure will be on going over to the furnace so the guys want to stand up and show what they have got.”

Carey, 26, was annointed as Test 'keeper Tim Paine's successor in a whirlwind week that included a maiden 20 ton and Australian 50-over debut against England last Friday at the Gabba.

"The dream came true, it was very exciting and I want to keep performing,” said Carey, who deputised for Paine who was floored by a stomach bug.

Carey returned to Strikers duty on Monday night against the Melbourne Renegades in a memorable 26-run triumph, expanding his season tally to a Strikers record 400 runs at 57.

Carey trails D'Arcy Short with 504 at 63 and Shaun Marsh's 412 at 58 for most runs in a domestic T20 season.

"I am definitely confident and having a bit of fun out in the middle,” said Carey, who was presented with his Australian one-day cap by Test great Ian Healy.

"I guess 400 runs is pretty cool, a record for the Strikers and third on the all time record but there is another game to win.

"To win eight out of 10 games would be a huge effort for the Strikers leading in to the finals.”

Carey said the catch by Ben Laughlin and Jake Weatherald to dismiss Renegades batsman Dwayne Bravo, which has attracted international attention, capped Adelaide's "best win of the tournament”.

"That was the best catch I have seen on a cricket field and probably the most amazing piece of play I have seen in sport,” Carey said.
