ELMONT, N.Y. - Boisterous won last year’s Grade 3 Knickerbocker Stakes and will go for a repeat when that 1 1/8-mile turf race is run for the 52nd time Saturday at Belmont Park. Boisterous, trained by Shug McGaughey for the Phipps Stable, won the Grade 3 Fort Marcy over a yielding Belmont turf in May. Since then, he was third in the Grade 1 Manhattan, second in the Grade 3 Arlington Handicap, and ninth in the Arlington Million. Boisterous, who will be ridden by Jose Lezcano, drew post 4. Also on Saturday is the Grade 3, $150,000 Athenia Stakes at 1 1/16 miles, which drew an evenly matched field of nine. Dealbata, runner-up in the Grade 3 Noble Damsel for trainer Chad Brown, drew post 7 and may rate a slight favorite. Others entered include La Cloche, Ruthenia, Embarr, Laughing, The Underling, Thundering Emilia, Martita Sangrita, and Law of the Range.
