Sent to the extreme outside in the home straight, Akerra rounded up her rivals with a couple of huge bounds before driving clear to win by an increasing two-length margin at the winning post.
Visiting South Island apprentice Kozzi Asano also showed his future potential when he produced a well-judged effort to land London Express as the winner of race three with Mars Bars finishing on in to second to provide Sharrock with the quinella.
Schofer made it three wins from her first four rides when Collinstreet snatched victory in race four with a late lunge to deny race favourite Secret Squirrel and chalk up a winning quartet for Sharrock.
Allan, who has been confident of a good day for the stable before racing commenced, was chuffed with the performance of all of his winners, with Schofer's ride on Akerra being singled out for special praise.
"Normally a kid in that position would have panicked on a $2 favourite," he said.
"She just let it slide up behind them and had one run from the 500m. It was a big performance. I don't want to do too much more with Akerra as she will be a bonny mare in the autumn."
Sharrock admitted Tavi Mac held a special place in his stable, although he jokingly described him pre-race as having the looks and stature of Tolkien character, Frodo Baggins.
"He's a lovely little horse and is a bit special to us as he is so small," Sharrock said.
"He hates getting beaten in a gallop and he travelled like the winner the whole way. He's out of a good mare (Bellaroof) and I think he will go through the grades."
Sharrock was also pleased to see London Express bounce back to winning form after producing some muddling efforts since a fresh-up success at Trentham back in early May.
"Kozzi rode her perfect, as we blew it last start when we rode her on speed. She'll be better in the Autumn as well but there is a weight-for-age stakes race in two weeks and
she has won good enough to say she will be a chance."
