Stoney, winning his fourth straight race since being claimed for a bargain $20,000, scored a 1 1/2-length victory in the $100,000 California Sprint Championship at Bay Meadows Saturday.
Stoney was claimed on May 31 at Hollywood Park by trainer Ruben Cardenas, who promptly gelded the 4-year-old son of Bold Badgett.
"He was very studdish," said Cardenas. "We gelded him and I think that has made the difference."
Stoney, who had just one win in nine starts prior to joining the Cardenas barn, is 4-for-4 for the trainer and his clients, Stephan and Cyndi Weeks. Stoney earned $55,000 for Saturday's win and has already returned $175,060 on the Weeks' $20,000 investment.
In the California Sprint Championship, a six-furlong contest for horses bred in California, Stoney ran down the speedy El Dorado Shooter in the final furlong in an impressive 1:08.44.
Ridden by Russell Baze, Stoney rallied from last in a field of five.
"As soon as I got him in the clear, he accelerated," said Baze. "He really came with a big run. He's a racehorse."
Stoney was a 6-5 favorite in the California Sprint Championship and paid $4.40. Cardenas said Stoney will likely make his next start in the $150,000 California Cup Sprint at Santa Anita on Nov. 2.
