Baeza, who has finished second or third behind top 3-year-old Sovereignty in his last three starts, continued his progress toward a scheduled start in the Grade 1 Pennsylvania Derby at Parx Racing on Sept. 20 with a five-furlong workout in 59.40 seconds at Del Mar on Friday.
Baeza worked alone and had one of the quicker times of the morning at that distance.
“Usually he doesn’t work that well by himself,” trainer John Shirreffs said. “He looked good today.”
