Homeboykris collapses, dies after win at Pimlico Race Course

— -- BALTIMORE -- In a tragic start to Preakness day, the winner of the first race at Pimlico Race Course has died on his walk back to the barn.

Homeboykris had rallied to win the race by a half-length on a rainy Saturday. After having his picture taken in the winner's circle, he collapsed and died. Track officials believe the 9-year-old gelding suffered cardiovascular collapse.

The horse will be taken to New Bolton Center in Pennsylvania for an autopsy.

Homeboykris won the Champagne Stakes in 2009 and a year later finished 16th in the Kentucky Derby with former New York Yankees manager Joe Torre as a co-owner. He had just won his 14th race in 63 career starts and fourth in six races.

Later Saturday, Kentucky Derby winner Nyquist will take on 10 rivals in the Preakness Stakes.
