Mary Grum's COSMIC (El Prado [Ire]), receiving a patented, rail-skimming ride from Calvin Borel, romped to a 4 1/4-length victory over Godolphin Gray (Explicit) before a crowd of 28,011 to win Friday's $52,270 Dark Star Purse, the featured allowance attraction on the first program of night racing in the 135-year history of Churchill Downs.

Chip Woolley, trainer of Kentucky Derby (G1) winner MINE THAT BIRD (Birdstone) who is based in New Mexico, liked what he saw of the first night program.

"I thought for the first time, they did an awesome job. It was a great, great deal," Woolley said. "I got here about 7 o'clock and when I turned the corner driving in I saw all the people on the balconies and it looked just like Derby Day."

"I ran at 7:30 and it wasn't dark yet. I like to walk over with my horses and I can usually count the people in the stands. I couldn't do that last night. I hope they all come back," veteran Kentucky-based trainer Steve Penrod admitted.

One other big winner on the night was Ocean Colors (Orientate), the next-to-last foal of 1988 Kentucky Derby queen Winning Colors, who made her turf debut in the 4TH race. The gray lass posted a 2 1/2-length victory in the five-furlong grass allowance, her second win after taking her maiden debut by 5 1/4 lengths on Churchill's main track last June.

"She ran big last night and she's fine this morning," said Scott Blasi, assistant to trainer Steve Asmussen. "I am not sure what we are going to do next with her, because there are not that many races that fit her at five and five and a half furlongs."
