ARCADIA, Calif. — Barnes defeated stablemate Romanesque by 5 1/2 lengths to win the $200,000 San Vicente Stakes for Hall of Fame trainer Bob Baffert in a field of Kentucky Derby hopefuls on Saturday at Santa Anita.

Ridden by Juan Hernandez, Barnes ran seven furlongs in 1:22.15 and paid $4, $2.80 and $2.10 as the slight even-money favorite. The 3-year-old colt had $307 more in the win pool than Bullard.

“I knew he would run well,” Baffert said. “I was watching Juan, he knows the horse well, and he said he was a little green. But everyone who has worked him says he has another gear. They are all a little green. The second (race) out is the most important for all these horses.”

Barnes improved to 2-0. He was purchased for $3.2 million as a 2-year-old by owner Amr Zedan.

“He had to really stretch to get this horse,” Baffert said. “When you have clientele like that, it is everything.”

Romanesque, also trained by Baffert, returned $5.20 and $2.40. Bullard was another half-length back in third and paid $2.10 to show.

Making his second career start and first in a stakes race, Barnes dueled on the lead with McKinzie Street in the opening half-mile. Barnes spurted away midway through the second turn and ran strongly through the stretch to close out the win.

“He’s really good. I love him,” said Hernandez, who was riding Barnes for the first time. “He was aggressive down the backside but he’s still learning how to run. I like him because around the quarter pole he got off the bridle and was kind of looking around a little bit. But when I corrected him, he came back to me. I was really surprised how he finished today.”

Baffert said Barnes reminded him of his 2015 Triple Crown winner American Pharoah.

Barnes is named after Baffert’s longtime assistant, Jimmy Barnes.

“They surprised me and I was honored,” Barnes said. “I was a little nervous, but it is working out well so far. I had a little bit of a knot in my stomach, but it will only get better after this.”
