ARCADIA, Calif. – Champ Pegasus, the runner-up in the 2010 Breeders’ Cup Turf at Churchill Downs, has been taken out of training because of a recent injury and may be retired to stud, trainer Richard Mandella said on Wednesday. Unraced since a second-place finish in the Grade 2 Clement Hirsch Turf Championship at Santa Anita in October 2011, Champ Pegasus was an intended starter for the Grade 1 Citation Handicap at Betfair Hollywood Park on Nov. 25 when an injury surfaced. “It’s a reoccurrence of an old problem,” Mandella said, declining to be more specific. Mandella said a decision will be made soon whether the 6-year-old Champ Pegasus stays in training or is retired. “We’ll spend the next few weeks deciding whether to give him a rest and try to race next year or go to stud,” he said. A three-time stakes winner, Champ Pegasus has won 5 of 14 starts and $1,052,520.
