Australian star sprinter Hay List was put down Feb. 3, 2015, after battling laminitis. The gelding was 9.

Foaled Aug. 24, 2005, in Australia, the bay horse had a white stripe.

Hay List was hugely popular in Australia due to his ongoing rivalry with unbeaten mare Black Caviar.

He had been fighting laminitis since mid-December 2014. In his final weeks, the horse “was taking two steps forward, five steps back,” according to trainer John McNair, who had been caring for him with his wife, Sue.

Hay List “had a terrible night (Monday), and we could not put him through that again.”

The horse reportedly had chronic hoof problems throughout his career yet still went on to be rated the world’s second-best sprinter behind Black Caviar.

Hay List won 15 races in 28 starts, earning $2,559,575. He had Group 1 wins in the Newmarket Handicap. All Aged Stakes and Manikato Stakes. He ran second to Black Caviar in four Group 1 races.

Hay List recovered from two colic surgeries and a fractured knee.

The horse was by Statue of Liberty out of Sing Hallelujah. He was bred and owned by T. J. Davenport.
