Leading jockey Craig Williams made the trip to Mornington for one ride and came away a winner aboard a horse he insists is headed to Stakes grade.

The Charlotte Littlefield -trained She's Bulletproof took out the Big Event Picnic Tables Plate (1200m) on Wednesday at her second start, although it was not as easy as her starting price of $1.24 suggested.

Sitting outside of the leader, She's Bulletproof held off a late challenge from Pink Chandon ($8.50) to score by a half-neck with Savee ($6.50) holding on for third, a further 1-1/4 lengths away.

Williams partnered with She's Bulletproof when the filly was placed at Moonee Valley on debut last month and said she was still inexperienced.

"She's a really nice filly and this is one of the first stepping stones for her," Williams said.

"She did show her inexperience a couple of times. She was having only her second race start and she did appreciate finding firmer footing in the straight.

"I was really happy and pleased. She looks great and Charlotte and her team is managing her well and she's an exciting 'Black Type' filly in the making."

Littlefield returned late on Monday after a holiday in the UK visiting her parents in time to see She's Bulletproof salute on Wednesday.

She's Bulletproof was bred by Littlefield's husband Julien Hay and continues a successful run the stable is having.

Wednesday's victory was Littlefield's fourth winner from her past 10 starters with three placegetters thrown in for good measure.

"It's what happens when you have good horses coming through, a good team around you and I can go away on holidays more often," Littlefield said.

"But I'm glad I was here to see that."
