With a victory aboard Tambora in the fifth race at Parx Racing Sunday afternoon, jockey Roberto Rosado won the 1,000th race of his career. A native of Puerto Rico, Rosado has been riding professionally here in the United States for more than 20 years. In 1997, he and jockey Phil Teator shared the Eclipse Award as the nation’s top apprentice. His son Johan has followed in his father’s footsteps and has become one of the top apprentice riders in the area, beginning here at Parx before shifting his tack to Maryland this past summer.
