DUBAI, United Arab Emirates — Hall of Fame trainer Bob Baffert had a heart attack early Monday in Dubai where he was preparing to run Game On Dude in the $10 million Dubai World Cup.

Baffert's assistant, Jim Barnes, said from Santa Anita racetrack in Arcadia, Calif., that Baffert was "doing very good" after having three stents inserted in two arteries. Barnes said he had spoken to the trainer's wife, Jill, who had accompanied her husband to the Middle East, along with their young son, Bode.

Barnes said Jill Baffert told him the procedure went well and "everything should be fine."

Bernie Schiappa, co-owner of Game On Dude, said the 59-year-old trainer wasn't feeling well on the long flight to Dubai, and was tired after visiting the barn and arriving at the hotel.
