LEXINGTON, Ky. &ndash; A $50,000 weanling by first-crop sire Tiz Wonderful led a parade of young stock at the top of the Keeneland November breeding stock sale&rsquo;s prices Monday.\r\nMonday&rsquo;s session was the eighth of 13 and followed a weekend of decreases in gross receipts, average price, and median price.\r\nThe session-leading Tiz Wonderful colt sold to Indian Creek, agent, and was part of agent Susan Forrester&rsquo;s consignment. The dark bay or brown colt out of Wildwife, by Wild Gale, is a half-brother to Grade 3-placed stakes-winner R Loyal Man.\r\nAt 3 p.m., the Tiz Wonderful colt was the day&rsquo;s most expensive horses. The top five prices were for weanlings. The highest-priced mare at that point was Hip No. 2649, the $39,000 Mr. Greeley mare What a Trouper. Jody Huckabay, agent, signed the ticket. Paramount Sales agency was the seller.\r\nWhat a Trouper, 5, was cataloged in foal to Langfuhr and is from the family of French stakes-winner Limelighting and American stakes-placed runner Thunder and Rain.\r\nOn Sunday, Grade 1 winner Nonsuch Bay was the only six-figure horse at the auction&rsquo;s seventh session. A 11-year-old Mr. Greeley mare, she brought $210,000 from SF Bloodstock. She was cataloged in foal to A. P. Warrior. Stonewall Farm sold Nonsuch Bay through the Bluewater Sales agency, the court-appointed receiver in Stonewall&rsquo;s bankruptcy.\r\nNonsuch Bay earned $747,078, including the Mother Goose Stakes, the Grade 2 Nassau County Breeders&rsquo; Cup Stakes, and consecutive victories at 4 and 5 in Gulfstream&rsquo;s Banshee Breeze Handicap.\r\nCumulatively, through Sunday&rsquo;s seventh session the auction had sold 1,664 horses for a combined $132,349,800, which was down 9 percent from last year at the same point. Through last year&rsquo;s seventh session, 1,545 horses had sold.
