NEW ORLEANS – Little Polka Dot and Bella Medaglia might have been a little disappointing in their most recent races at Fair Grounds, but the two fillies are in much different positions coming into Friday’s featured sixth race here. Bella Medaglia must prove that after a long layoff she remains the same filly who finished second by a half-length in the Tiffany Lass Stakes last winter. Little Polka Dot, for her part, only needs to rebound to the form she showed Nov. 10 at Delta Downs to be a major factor in Friday’s first-level optional $25,000 claimer at a mile and 70 yards.
