A race-to-race double at Mornington gave Mick Kent reason to smile but the trainer was only at the meeting because his passport was stolen in a recent burglary.

Kent intended to be in New Zealand on Monday for the Karaka yearling sale but discovered his passport was among items taken when his house was burgled last weekend.

He said two laptops, sunglasses, watches, alcohol and his passport were taken.

"The passport was annoying. The rest of the stuff was irrelevant, really," Kent said.

Three-year-old Mysonharry ($3.80) broke through for a short-half head win in the Window Warehouse Maiden Plate (1525m) while recent stable addition Written raced wide in the lead in the Total Commercial Cleaning Handicap (1225m) and kept going strongly to win by 2-1/4-lengths in her second start for Kent.

Formerly trained in Sydney by Kent's friend and the filly's part-owner Craig Carmody, Written was sent south as she is eligible for Super Vobis bonuses in Victoria.

Kent believes Written is most comfortable being allowed to bowl along and was happy with how things panned out in the race.

"We were happy to sit off the fence because we thought the track was slightly better out there, plus you've got no-one going outside you when you are off the fence," he said.

"It worked well."

Kent also believes Mysonharry can progress to better things off his maiden win at his sixth start.

"I've had a lot of time for him and he had to win today, I thought," Kent said.

"I think he'll get to Saturday grade as a three-year-old and he probably wants 10 furlongs (2000m)."
