Oakleigh Plate-winning sprinter Queman has died after a battle with colic.

Trainer Shane Oxlade confirmed the news to Racenet on Tuesday morning.

"They put him down this morning," Oxlade, who trains in partnership with daughter, Cassie, said.

"Unfortunately, we lost the battle.

"It would have been great to get him home, where he could just wander around the paddock for the rest of his life, but it was never going to happen unfortunately.

"Some of them do horrendous things to themselves and they survive, and then the simplest things bring them undone.

"It's sad – it's devastating – it's all of those things, and we are on the end of it this time."

Oxlade transported the son of Mint Lane to Morphettville's Equine Clinic when he began exhibiting symptoms of colic over a week ago.

The Group 1-winning sprinter won the 2024 Oakleigh Plate, the Oxlade pair's first Group 1 triumph.

Owned and bred by Francis "Boof" Smith and family, the seven-year-old gelding won over $1m in prizemoney for connections with 10 race wins, three at stakes level, under Shane and Cassie Oxlade.

Queman's last victory was a gutsy first-up win in the 2025 Group 3 Behemoth Stakes following a 69-week break.
