"He didn't like the whip much so I just kept slapping him on the shoulder."Presidio Heights, a 5-year-old gelding who has had 17 career starts, is trained by Art Sherman and owned by William J. Zellerbach of San Francisco. Bred in Kentucky, Presidio Heights earned his second stakes win and his sixth career victory. "I always knew this horse had talent but he was accident prone," said Sherman. "He needed time to develop as a 3-year-old and it's really paid off now. We found a hairline fracture in his hind leg with the nuclear scan and gave him eight months off for it to heal." Presidio Heights earned $33,650 for the Danville victory and paid $12.20 as the third betting choice in a field of six. El Dorado Shooter, ridden by Russell Baze, easily took second by three lengths over Texas Chili."At the sixteenth pole I saw Presidio Heights stick his head up in the air and I was sure I was going to blow by him," said Baze. "But then my horse ran out of gas. My horse never quit, he just ran out of gas."
