Paceman Henry Thornton claimed the best-ever figures for an Australia A side taking 7-39 to help bowl the team to a 108-run win over New Zealand A.
After the hosts were all out for 243 in Brisbane, Thornton rolled through the New Zealanders by taking the first seven wickets.
Called into the squad on the eve of the match, Thornton took three wickets with his first four balls and was twice on a hat-trick in the innings.
His victims included Tom Bruce and Cam Fletcher for first-ball ducks, while a third New Zealander in Dean Foxcroft was also out for nought.
Thornton's figures are the second such time the 26-year-old has run through a team in elite cricket, having taken 5-3 for Adelaide against the Sydney Thunder in the BBL last year.
They also came in his first match for Australia A, having previously represented his country in U19s.
"I'm pretty speechless," Thornton said.
"Dad was in the crowd and was going ballistic.
"I was speaking to Ryan Harris and I said I felt like I am really ready to go, I have had a huge pre-season.
"I have worked really hard with him on a few things (as South Australia bowling coach), especially in the white-ball space.
"It was such a bonus these games came at the right time."
Earlier, Ben McDermott smashed 70 off 59 balls for Australia A to help set up the win.
Matt Renshaw also hit 43 and Josh Philippe 35 off 25 before Australia A collapsed from 2-170 to be all out for 243 in 44.1 overs.
The win gives Australia a 2-0 lead in the three-match series with the third game to be played in Brisbane on Friday.
