Firmed as the hot favourite at $1.90, the three-year-old bay filly jumped from barrier two the seven-horse Bathurst RSL Club Benchmark 66 Handicap (1400 metres) to eventually pull ahead for the win.

Bathurst trainer Dean Mirfin said he was very happy with how the filly ran.

"She came out here to do a good job and she's done a good job today," she said.

"She's now won three out of three, so I'm very happy with her."

While Press Box got a preferable jump at the start, it was the Ian Holland-trained mare Crim ($8.50) that got to the best star, with the Bathurst-trained filly just behind after 400 metres.

As the race progressed down the back straight, Mr Trindall ($9) did his best to threaten the leading Crim, pushing ahead of Press Box into second.

But as the horses straighten up for home, Mr Trindall slipped back and Press Box pulled ahead to the front, a position she never relinquished.

The Danny Parsons-trained Sonic Girl ($16) did her best to cause a few problems, the fast-finishing mare finishing just under a length behind the winner.

Legistation ($31) was almost three and half lengths back, with the Wade Slinkard-trained chance finishing fourth.

Second-favourite Buffy ($3), from Gary Portelli's Warwick Farm stable, ran fifth, while big outsider Fanny Chenal ($71) come in at sixth for Orange-based trainer Alison Smith.

Mr Trindall, who had previously proven a chance for the front, finished in last spot, a disappointing result for the Canberra-trained gelding.

The win brought about Press Box's third career win in just her third start since coming into Mirfin's stable.

Her last start under her old trainer Chris Walker came at Canterbury in February, which resulted in a fifth place finished.

Her two previous wins came at Bathurst on Anzac Day and at Parkes on May 12, with the Bathurst win bringing home a handy $11,200.

But Press Box is headed for a break, for Mirfin attempts to crack a win with her at Sydney.

Rain had fallen the day before in Bathurst, but the track was rated a soft five.

However, the breeze was extremely chilly track side but Press Box seemed to cope with the weather well.

"She probably coped better than most of us," Mirfin said with a laugh.
