Cambiocorsa's love affair with Santa Anita's downhill turf course deepened Sunday when the 4-year-old gray filly extended her unbeaten streak over the layout to seven with a three-quarter length victory over hard-charging Lock And Key in the grade III, $100,000 Las Cienegas Handicap.In taking her sixth straight over the winding configuration – fifth at the current Santa Anita meet -- the California-bred daughter of Avenue of Flags achieved her first graded stakes win while covering the 6½ furlongs in 1:12.60."I've been riding for 25 years and I've never been involved with a horse who's won this many (six) in a row," jockey Jon Court said afterward. "She's just unbelievable."The speedy Cambiocorsa dueled with Starkay early, disposed of her and spurted four lengths clear in midstretch as the 8-5 favorite. Lock And Key, the 19-10 second choice, closed boldly from fourth, but couldn't overtake the course specialist. It was 4¾ lengths further back to Sandra's Rose, third in the field of nine."She jumped out there with Starkay and just kind of relaxed and set her own pace," Court said of the winner. "When we crossed the dirt (turning into the stretch), I called on her, and she gave me a quick three or four lengths. I'm just lucky I'm the rider who's had the opportunity to sit across her back."Court has been aboard for six of the filly's wins. Aaron Gryder was the rider in her other victory.Cambiocorsa, who carried high weight of 120 pounds, paid $5.20, $3.20 and $2.40. Lock And Key paid $3.20 and $2.40. Sandra's Rose, ridden by Martin Pedroza, paid $2.80 to show.The winning purse of $67,740 boosted Cambiocorsa's earnings to $360,745 for the partnership of Leatherman Racing LLC and Ran Jan Racing Inc. from an overall record of 7-0-2 in 12 starts. She has never finished better than third anywhere but over Santa Anita's downhill course.
Trainer Doug O'Neill said he wasn't sure what might be next for Cambiocorsa, but indicated he might consider stretching her out to a mile. In her last start at one mile over Hollywood Park's turf course, she faded to fifth following a pace duel.With a three-day Pick Six carryover sending $4,067,295 into Sunday's total pool, winning Pick Six payoffs were worth $91,977.40 to 30 participants.
