"Diamond Joe, a fan favorite in Nebraska and the most successful son of 1995 Arkansas Derby winner Dazzling Falls, has been retired, trainer Chuck Turco said on Friday. Diamond Joe ranks fifth all time among Nebraska-breds in earnings, a list topped by his sire. Turco also trained Dazzling Falls.
“It was a great run with Joe, that’s for sure,” said Turco.
