Dack Janiel’s set the pace, covering the mile in 1:38.90 and maintained the lead until the far turn when Ry’s the Guy moved to the front with Lone Rock right behind him. The top two hit the top of the stretch together with Lone Rock going the better of the two and gradually pulling away.
“I wanted to stay off the horse on the lead in second, but in that situation, I had to ease back a little bit,” Vazquez said. “I had some traffic in front of me, so I had to ease him back. When I hit the far turn and had a lot of horse, I knew we would be tough. To win a stakes here Kentucky Derby Week is incredible. That’s why we do this, so I’m just really fortunate. It’s an amazing feeling.”
The victory was worth $78,684 and increased Lone Rock’s career bankroll to $528.921 with a record of 32-10-3-2. Lone Rock is a 6-year-old Kentucky-bred gelded son of Majestic Warrior out of the Hard Spun mare Ruby Lips.

“A lot of horses can’t go that far, but he’s a pro,” Diodoro said. “He loves to train. The further he trains, the better he gets. He was so relaxed compared to many of those horses and that’s what you need when you’re going that distance.”
