Keeneland’s reformatted September yearling sale catalog will number 4,857 this year, down 6 percent from last year in a climate of shrinking North American foal crops. The September sale will run Sept. 12-26 at Keeneland’s Lexington sale pavilion. But this year its first two sessions, the auction’s select portion, will be limited to a total of 211 yearlings and will be held at night. Traditionally, the sale’s first two days have been all-day sessions. The 2010 evening sessions on Sunday, Sept. 12, and Monday, Sept. 13, will begin at 7 p.m. The sale will continue with daytime sessions Sept. 14-26, with a dark day on Sept. 18. All daytime sessions will begin at 10 a.m. The 2010 catalog consists of 2,562 colts, 2,292 fillies, and three geldings by a total of 294 domestic and foreign sires.
