Two more horses have perished at Belmont Park, bringing that track’s 2014 Kill Total to 36: 4-year-old Zaikov, who hadn’t been raced since last December, went down – fractured humerus – while training yesterday morning. For trainer Todd Pletcher, that’s seven dead horses at NY tracks this year. The other horse, 4-year-old Perfect Danger, was felled by post-surgery laminitis. The Eugene Reiff-trained colt was last raced at Saratoga in August.
