Winona Writer and Mach Assassin gave Hewitt a winning double to start the meeting before Cala Jane made it three victories before the clock had hit 7.30pm.

Hewitt's two-year-old Chap Daddy then rounded out the meeting on a high note by making it back-to-back wins in his new preparation.

Mach Assassin's success in the second event of the night, the Australian Pacing Gold Pace (1,730 metres), was one of the more dominant victories of the meeting.

He was sent out as a $2 favourite and didn't disappoint.

Driver Jason Hewitt had it all his own way out in front and after hitting the lead early from gate four he was able to control proceedings in just the way he wanted.

With a pair of 31.5 quarters to start the race Hewitt dialled back the tempo to save up his leader for a big finish.

The race's second favourite Happy As ($2.60, Mitch Turnbull) swung out three wide to make a run from the back of the pack but after the comfortable pace of the opening half he had a lot of work to do.

Turnbull's runner finish strongly down the outside but Hewitt only needed to give Mach Assassin the slightest bit of encouragement to make him break away from his challengers.

He won by 6.6m over Happy As, finishing with back-to-back 28.3 quarters to run a mile rate of 1:58:8.

Sport Cadet ($10, Michael Muscat) was third.

"He felt super. He got it easy in front and everyone left him alone tonight. He was great all the way to the line," Jason Hewitt said.

"I had Mickey Muscat outside of me making a lot of noise and I think that stirred him up a bit and all I had to do was ease the reins and off he went.

"I've had a couple of drives on him before for not much so it was nice to win one with him. It was nice for him to show what he could do.

"I worked him at home a few times and knew he'd go alright. He just had to do a bit too much work in his last few races but he was fitter from last week's run, which he showed tonight."
