Back in training at age three, Polynesian won five of his next seven starts, one of which was a division of the Sagamore Stakes.
In the Experimental Free Handicap he came in third to Jeep and Greek Warrior, and fourth in a division of the Wood Memorial won by Hoop Jr.
He skipped the Kentucky Derby (won by Hoop Jr.), instead competing in one mile Withers Stakes where he defeated Pavot.
[2] Because of its demanding one and a half miles, Polynesian was not entered in the third leg of the Triple Crown, the Belmont Stakes.
Retired to stud duty, Polynesian sired 37 stakes winners including one of the greatest horses in American racing history, Native Dancer.
