(CNN)Sir Winston, ridden by Joel Rosario, won the Belmont Stakes, the third contest in US horse racing's Triple Crown.
The win gave trainer Mark Casse a second Triple Crown win this season.
Race favorite Tacitus was second and Joevia was third in Saturday's contest.
The winning time for the 1 1/2-mile race was 2:28.30, four seconds off the record set by Secretariat in 1973.
"He's a very nice horse. You have to let him do his thing," Rosario told race broadcaster NBC. "I just took my time with him."
Rosario also rode Tonalist to a Belmont win in 2014.
