Rockport Harbor was euthanized Aug. 2, 2013, due to laminitis. The stallion was 11.

Born in 2002, he was bred in Kentucky by Heiligbrodt Racing Stable and Taylor Made Farm. The colt was dappled gray with a white blaze, two white stockings and two white socks. He was out of Unbridled’s Song by the stakes-winning Copelan mare Regal Miss Copelan.

He raced for owner Rick Porter during the mid-2000s and was undefeated as a juvenile with wins in the Grade 3 Nashua and the Grade 2 Remsen at Aqueduct.

Porter bought the yearling colt for $470,000 at the 2003 Keeneland September yearling auction.

Rockport Harbor won five out of eight starts and earned $324,800.

He suffered a hoof injury in 2004 in the Grade 2 Remsen.

Rockport Harbor stood at Darley’s Jonabell Farm in Lexington, Ky., for his first six seasons, then moved to Dr. William Solomon’s Pin Oak Lane Stud in New Freedom, Pa., in 2012.

At the time of his death, his progeny had nearly $3.1 million in earnings.
