Sent to the track as a two-year-old, under jockey Steve Donoghue The Tetrarch easily defeated his competition. Quickly dubbed the "Spotted Wonder," he easily won all seven of his 1913 starts. In his one real test he came from behind to capture the National Breeders' Produce Stakes by a neck, but that one close finish only resulted after a mix-up at the start that left him four or five lengths back. An injury in October 1913 ended The Tetrarch's two-year-old racing campaign. The following spring he reinjured himself in training. His handlers were hoping he would heal sufficiently to return to racing, but by the end of 1914 came to the conclusion that he would never race again.
