Hall of Fame horse trainer D. Wayne Lukas has died. He was 89. His family says Lukas died at his home Saturday night. Lukas had been hospitalized with a severe MRSA blood infection that caused significant damage to his heart and digestive system and worsened pre-existing chronic conditions. Lukas won 15 Triple Crown races, including the Kentucky Derby four times. Only good friend Bob Baffert had more Triple Crown victories. The beloved, old-school trainer known affectionately as “Coach” was still getting on the pony himself in the morning for workouts even with his 90th birthday approaching.
