The Carter Sales Co. OKC Summer sale closed Sunday with gains in gross and average, led by a filly from the first crop of Kentucky stallion Flashback. The single-day yearling and mixed sale saw a combined 65 horses sold for revenues of $531,400, up 18 percent from last year’s auction when 58 horses brought $450,500. Sunday’s average sale price rose 5 percent to $8,175 from $7,767, while the buyback rate improved to 23 percent after finishing at 36 percent in 2016. “This was the best catalog in our sale’s history,” said sales manager Terri Carter. “It was strong across the board and that made the sale so much fun for everyone. The atmosphere was just so energized.” Phil Adams bought the sale-topper, a first-crop Flashback filly, for $55,000. :: DRF BREEDING LIVE: Real-time coverage of breeding and sales The chestnut filly is out of the unraced Tiznow mare Tiz Merry, whose first foal to race is a winner. She is from the family of Grade 3-placed stakes winner Candy Ball, stakes winner Rising Moon, and Puerto Rican group stakes-placed Feliu and Sofia T. Scott Pierce and Ciaran Keveaney bred the filly in Oklahoma, and she was consigned at the OKC summer sale by Buena Madera as agent for Hidden Creek Farm. It was the second time the filly has been offered at public auction, after finishing under her reserve as a weanling with a final bid of  $16,000 at last year’s Keeneland November breeding stock sale. She is the second-most expensive foal out of Tiz Merry to sell at public auction, trailing the Into Mischief gelding Deal Driven, who brought $85,000 from Zayat Stables at the 2015 Keeneland September yearling sale. Deal Driven has won 3 of 11 starts. To view the auction’s full results, click here.
