Hall of Fame trainer D. Wayne Lukas, who won the Preakness Stakes in Baltimore seven times, died on Saturday night, his family said.

Lukas won 15 Triple Crown races across his six-decade career, the second-most only to Bob Baffert. He won the Kentucky Derby four times and has a record-tying 20 wins in the Breeders' Cup World Championships. He won 4,987 documented Thoroughbred races, and his horses have won more than $310 million in more than 30,600 starts.

Lukas died on the evening of June 28 at age 89. He was hospitalized in Louisville last week after a severe MRSA blood infection caused significant damage to the thoroughbred trainer's heart, digestive system and worsened preexisting chronic conditions, according to a statement from the Lukas family.
