Wood Memorial (gr. I) winner Bob and John and Santa Anita Derby (gr. I) runner-up Point Determined both worked five furlongs in a bullet :59 1/5 at Santa Anita Tuesday as they begin their serious training for the Kentucky Derby presented by Yum! Brands (gr. I).Bob and John worked by himself with jockey Garrett Gomez aboard, while Point Determined worked in company with Victor Espinoza up. The works were the fastest of 24 on the tab.Trainer Bob Baffert actually clocked Bob and John in :58 4/5 and caught Point Determined in 1:00 1/5. The latter worked with the 3-year-old maiden Evaluate."They both went really well and are happy campers," said Baffet, who has not made up mind yet when he will ship Bob and John and Point Determined to Louisville. Sinister Minister vanned to Churchill Downs following his victory in Saturday's Toyota Blue Grass Stakes (gr. I).Although nothing has been firmed up yet, it looks as if Gomez will stick with Bob and John for the Derby and Rafael Bejarano will ride Point Determined. That could leave the mount on Sinister Minister open for Espinoza, who piloted War Emblem to a wire-to-wire victory for Baffert in the 2002 Kentucky Derby.
