A powerful finish from Dig A Pony in the Rivette Series Final at Flemington has capped a successful winter campaign for the filly.

The Peter Moody-trained three-year-old was a well-supported $2.45 favourite in Saturday's $120,000 race and powered home from well back in the field to notch her third win from four starts this campaign.

Her victory on Saturday stamped her authority during this year's six-race series for fillies over winter having also won the only two heats she contested.

While Moody is not getting carried away with Dig A Pony's off-season form, he will look to give her a chance in better company next season.

"A couple of weeks ago we thought she might have nearly come to the end of it but she has done well the past 10 days and done a good job," Moody said.

"We're not getting carried away with winter form but we've probably got to lift the bar a bit now.

"Maybe we'll take the foot off the pedal and chase a little bit of black type at the end of the spring, dodging the A-graders."

Dig A Pony had only a few behind her on the turn but overhauled her rivals to score by 1-1/4 lengths over Ardelle ($41) with a short half-head to Cuban Lass ($8) third.
