Calder: Vastly improved Evolution Rocks has best Beyers


The $65,000 Thrillin Discovery Handicap at Calder on Saturday runs directly through Evolution Rocks, a much-improved former claimer who comes off a string of 90-plus Beyer Speed Figures at Parx Racing and Gulfstream Park. Eight were entered in the Thrillin Discovery, a six-furlong sprint for 4-year-olds and up.
