Richard's Kid, two-time winner of the Pacific Classic, has been retired from racing with a leg injury.
The announcement was posted on trainer Doug O'Neill's Facebook page.
"It is with regret that we announce the retirement of multiple graded stakes winner, Richard's Kid. Richard's Kid has been retired due to a slight tendon tear ... It has been a pleasure to have such an incredible gentleman of a horse in our barn. We wish him well in his next career at stud. Plans to be determined at a later date."
The 8-year-old posted consecutive victories in the $1 million Pacific Classic at Del Mar in 2009-10 and was third in last year's edition behind Dullahan and Game On Dude.
The horse was previously trained by Bob Baffert until he was sold and transferred to O'Neill's barn prior to last year's Pacific Classic.
Richard's Kid started eight times in 2013, winning only the Cougar II Handicap at Del Mar for the second straight year.
Owned by Triple B Farms and partners, the 8-year-old finishes his racing career with 12 wins in 47 starts for $2,482,259.
