Feature simulcast race: Grade 1, $1.5 million Preakness Stakes on Saturday at Pimlico

Update: Gates open at 9 a.m. Saturday — one hour earlier than usual — as the Preakness program at Pimlico begins at 7:30 a.m. … Tribal Storm, who won the Lost in the Fog Stakes on Feb. 19 in a 20-1 upset, and Krsto Skye, who won the Albany Stakes on June 10 in a 62-1 upset, meet in Friday’s sixth race. The 5-furlong non-conditioned allowance on the grass is a prep for this year’s Albany Stakes, scheduled for June 9. Tribal Storm was claimed for $62,500 by trainer Ari Herbertson on April 26 when the horse finished sixth as the favorite. … Entries will be taken Thursday for the Alcatraz Stakes — a 1-mile grass race for 3-year-olds. Among the 15 nominees are Hardboot and Unpossible, the 1-2 finishers from the Silky Sullivan Stakes for California-breds on April 29. Also nominated was Fibonacci, who comes off of two decisive victories going 11⁄8 miles on the grass at Santa Anita. … Nominations close Thursday for the Grade 3, $100,000 All American Stakes on May 28.

Elsewhere: The Breeders’ Cup announced a major format change for this year’s event Nov. 2-3 at Churchill Downs.

The other nine races will be run on the Saturday program, including the Distaff, which had been the first-day feature in the previous 10 years.
