Yarraman Park’s champion sire I Am Invincible took the lead for the number of stakes winners this season to date when progressive three-year-old filly La Mexicana capped a memorable Cox Plate day for Jamie Kah in the Listed MVRC Ladbrokes Crockett Stakes (1200m) at Moonee Valley.

The Anthony and Sam Freedman-trained filly completed a 4-timer for Kah with a fighting short-half-head victory, her first in a Black type race.

It advances La Mexicana’s record to three wins and a third from four starts with earnings of $164,845.

“She’s a tricky filly this girl. She has a lot of talent, is a bit hard to manage but the team has done a good job tweaking her gear, and they have got her absolutely flying,” Kah enthused.

“I felt like Motty (Jamie Mott on Twain’s Express) had us covered 100 out, but this filly was just too tough. She is a temperamental little thing and didn’t want to get beaten.

“It’s been an amazing day. I am humbled to have been given these opportunities. It would have been great to have a crowd here, and I could have really celebrated. Nevertheless, I am appreciative of everybody.”

Purchased by Belmont Bloodstock Agency (FBAA) for $320,000 out of the Lime Country draft at the Magic Millions Yearling Sale, La Mexicana is the second winner from as many foals out of the stakes-winning Domesday mare Cailin Miss, who comes from the family of Group I winners Brewery Boy and Lygon Arms.

La Mexicana becomes the 59th stakes-winner for I Am Invincible and his seventh this season.
