ARCADIA, Calif. – Goldencents worked a sharp five furlongs in 59 seconds at Santa Anita on Friday for the final start of his career in the $1 million Breeders’ Cup Dirt Mile here Oct. 31. In the days following that race, Goldencents will be sent to Kentucky to stand at stud in 2015. Co-owner Glenn Sorgenstein thinks Goldencents can go out with a victory and win the BC Dirt Mile for the second consecutive year. “This is it,” he said Friday before the workout. “This is goodbye. This is beyond a good horse.” Goldencents certainly looked in top form Friday. Jockey Rafael Bejarano was aboard Goldencents for the workout. Santa Anita clockers timed Goldencents through an opening quarter-mile in 23.80 seconds, a half-mile in 47.80, and galloping out six furlongs in 1:11.40. Bejarano did not urge Goldencents through the stretch. There will be an additional workout for Goldencents next weekend, but trainer Leandro Mora described Friday’s exercise as “the big work.” Mora is training Goldencents for the Breeders’ Cup while trainer Doug O’Neill is serving a suspension for a medication violation through mid-December. Goldencents, 4, has won 6 of 17 starts and earned $2,494,000. He has won five stakes, including the 2013 Santa Anita Derby. Goldencents won the Grade 2 Pat O’Brien Stakes at Del Mar in August and was second, beaten a nose by Rich Tapestry, in the Grade 1 Santa Anita Sprint Championship on Oct. 4. On Friday, Midnight Lucky, unraced since a win in the Grade 1 Humana Distaff at Churchill Downs on May 3, worked six furlongs in 1:12, the fastest of 12 works at the distance. Trained by Bob Baffert, Midnight Lucky is a candidate for the $1 million BC Filly and Mare Sprint over seven furlongs Nov. 1. Valiant Emilia, who will be an outsider in the $2 million BC Distaff on Oct. 31, worked a mile in 1:38.80. She earned a fees-paid berth to the BC Distaff with a win in the Clasico Cesar Del Rio in Peru in June.
