It was race number two at Towac Park with the Gary Portelli trained Premosphere ($1.30) entering the race a heavy favourite with two second places in the four-year-old mare's first four starts.

Ridden by jockey Brodie Loy, Premosphere jumped out to an early lead with Reach for Joy ($151) and Skye Lover ($51) running close behind.

The favourite led by half a length with 600 metres to go. Once she beat off Skye Lover coming hard down the inside, Premosphere looked home and hosed as it extended its lead on the field.

But seemingly out of nowhere, Miss Capella ($19) and jockey Shaun Guymer made their move.

From the back of the track, the long-shot bolted up the outside for a finish too close to call on first viewing.

Hearts were in mouths to see whether the heavily back favourite had claimed victory, and after a photo finish it was confirmed that Premosphere got the win.

Speaking afterwards, Portelli said he was a little worried coming down the home stretch.

"When she was zig-zagging everywhere and I saw Jarrod Austin's horse coming I was thinking 'oh no'," he said.

"Brodie got beat $1.65 favourite at Bathurst the other day and I thought here we go again."

While the former Orange-based trainer wasn't able to be there in person on Tuesday, he was still pleased to see racing return to Towac.

"It's where I learnt my trade and learnt off some of the best trainers I've ever seen including Reggie Priest and Johno Johnson to name a few. They were legends and watching what they did, I still apply a lot of their methods that I plagiarised and use in certain circumstances depending on the horse," he said.

"It's always good to get back there and support the club and although the local trainers don't like to see the Sydney trainers win, we're not bringing our city class horses there. We're bringing the ones that are best suited over the mountains and they can get beat just as easy as everyone else's.

"It's hard to sit back and watch like every punter at home, but when they win it's a lot better feeling."

Running in third was Em Cee Gee ($10).

But that was far from the only action at Towac.

Race one featured hometown hero Allison Smith and her five-year-old mare Who's Tinny ($11).

With punters projecting the Orange pair to finish near the bottom, they did themselves proud with a fight to the end and a fourth place result.

Grabbing the win in the Southern Cross Austereo Bm58 Handicap (2100m) was favourite Will to Excell ($3.60).

The third race of the afternoon saw yet another heavy favourite heading into the start. Coal Crusher ($1.30) ridden by Zac Wadick was out in front by the 500 metre mark in the Epiroc CG&E Maiden Plate (1000m) and had to stave off some tough competition in Good Deed ($6.50) and DogFight ($31).

But with about 150 metres to go down the home straight, Coal Crusher's lead was too big to chase down and grabbed the victory by 1.5 lengths.
