THE $500,000 Grade 1 Diana Stakes on turf (10.56pm) kicks off opening Saturday at Saratoga with a field of six fillies and mares. Last year’s winner Sistercharlie went on to win the Breeders’ Cup Filly & Mare Turf and makes her seasonal debut here.

Chad Brown, predictably is four-handed as Sistercharlie returns to the track after putting in several solid workouts leading up to the race.
