Not only did she leave Fritzy Boy, a Group 1 winner, but also Hoover Boy and Jack's Boy, who were both winners.
Fritzy Girl was not a big mare, standing only 15.2 hands but foaled 10 times.
Eight foals were colts and the only filly - apart from the lost filly - was Miss Sara who is now herself a broodmare.
The inclusion of Fritzy Boy in the Masterton Cup field would greatly enhance spectator interest in a race which has traditionally been kind to locally-trained runners.
Elusive Tracy won it last year for Opaki trainer Aaron Bidlake and owner Barry Southey and Fritzy Boy won the previous year.
Masterton Racing Club has planned a special fun day for Saturday and aside from the racing has organised a full day of entertainment.
For the kids there will be a visit from Santa and the Christmas theme will extend to the jockey's room with the jockey of a "Santa's pick" in each race wearing a red Santa's hat.
Christmas cracker betting slips will be on-course, doubling as an entry form to put punters into a draw to win a $250 Mitre 10 voucher on the day.
Voucher winners across meetings taking part in the promotion then go into a national draw to win a Pacific Island holiday.
