LEXINGTON, Ky. - There is no such thing as magic blinkers, but after Groupie Doll swept to victory Thursday in the 11th running of the Grade 1, $300,000 Vinery Madison Stakes at Keeneland, there was plenty of talk about how blinkers helped the 4-year-old filly keep her focus.

"I think they helped a lot," said Rajiv Maragh, who guided Groupie Doll to a three-length score in the seven-furlong Madison. "They helped get her up into the race without doing too much. When I asked her, she really came with her run. She's got a lot of power."

I’ll Have Another, the winner of the Santa Anita Derby last Saturday, has returned to training at Hollywood Park, trainer Doug O’Neill said.

“He’s so full of himself, showing great energy,” O’Neill said.

Ultimate Eagle, the winner of the Grade 2 Strub Stakes but the beaten favorite in the Santa Anita Handicap last month, has been taken out of training until late summer, trainer Mike Pender said on Thursday.

“He’s getting a little rest,” Pender said. “I’d like to get him revved up and ready to go with an eye on the Breeders’ Cup.”

LEXINGTON, Ky. – Comedero had to scratch as the morning-line favorite from the $75,000 Hot Springs Stakes three weeks ago at Oaklawn Park after coming down with a mild fever. It’s just as well, since the alternative became the $175,000 Commonwealth Stakes, a Grade 2 race with more than double the purse and one in which the Arkansas-bred speedster looks like a dominant front-runner.

“This looked like a race where he could be lonely on the front end,” said Mike Stidham, who trains Comedero for Peter Redekop. “He’s got real sprint speed.”
