Trainer Rod Cone is hoping for a big afternoon at Northlands Park Saturday. Cone has significant horses entered in the three $50,000 stakes that are featured on the 10-race card: the Ky Alta, Chariot Chaser, and John Patrick. Cone thinks his best chance is with Boomtown Brat in the one-mile Ky Alta for 3-year-olds. Nonetheless, Maegans Princesses looks pretty live in the six-furlong Chariot Chaser for 3-year-old fillies and both Notoriously and Inca Beauty look like contenders in the one-mile John Patrick for fillies and mares. The Ky Alta, which goes as race 9, is the first middle-distance stakes for 3-year-olds at the meet and it should reveal which of the local horses will be moving forward to the richest race in Western Canada, the Grade 3, $300,000 Canadian Derby Aug. 20.Boomtown Brat is coming off a front-running win with Ruben Lara aboard in the six-furlong Western Canada June 18 ,and according to Cone he is coming up to the Ky Alta in great shape. He did have one concern, however.“The 10-hole isn’t the best post to start from going a mile,” said Cone. “He had a pretty easy time making the lead from the rail in the Western Canada. There isn’t anything you can do about it and he is doing really well, so he might be able to overcome it.”Lara retains the mount.There is plenty of potential speed in the field and it could set up nicely for Freedoms Traveller. Trained by Lianne Knechtel, Freedoms Traveller came from off the pace to win a first-level allowance race June 19. He ran a big race the last time he went around three turns, finishing second behind Bond James Bond in the one-mile Canadian Juvenile in his final start as a 2-year-old.Big Son of a Gun, trained by Robertino Diodoro, won three route races in California but has never run on dirt. Acting on behalf of Wes Hanson, Diodoro claimed Big Son of a Gun out of a win at Hollywood Park for $25,000 May 13. He ran on turf for the first time in a $40,000 claimer at Hollywood Park June 9, finishing fifth.Embellished figures to be favored in the Chariot Chaser, but she was a vet scratch when she was entered in a $32,000 optional race June 18 and could be vulnerable. Trained by Rick Hedge, Embellished finished first in three stakes as a 2-year-old filly but had her number taken down for causing interference in the Freedom of City. She was a sharp winner in her only start this year in a $40,000 optional race June 1. Her bullet four-furlong move in 46.20 seconds July 5 is a good sign she has recovered from whatever was bothering her in mid-June.If Embellished doesn’t run her race, Maegans Princesses could pick up the top prize. In her first start for Cone at Northlands, she scored a sharp front-running win over next-out winner Give Me Five in a first-level allowance race June 3. Smarty Jill is another serious contender. She showed a new dimension by coming from just off the pace to win a $32,000 optional race June 18.Alywyn will be a solid favorite to win the John Patrick. Trained by Jim Meyaard, Alywin had won four stakes in a row before finishing second to Classic Alley Kat in the Wild Rose. Inca Beauty could be dangerous if she clears early, and Cone is happy with the way Notoriously has recovered from a bout with colic that prevented her from running in the Wild Rose.Notoriously was the champion 3-year-old filly in Alberta last year, and in her only start this season she finished second to Classic Alley Kat in the Brighouse Belles at Hastings April 23. Hastings-based Summer Song will look to regain her form after a dull effort as the even-money favorite in a $40,000 at Northlands optional race June 25.
