Seven horses headed by the 3&#45;year&#45;old The Gurkha and the 4&#45;year&#45;old Time Test are set to take their chances Saturday at Sandown Park in the Group 1 Eclipse Stakes.The Eclipse is the historical jumping&#45;off point for 3&#45;year&#45;olds to start facing older horses, and Golden Horn won the race last year for his first victory outside of his age set. The Gurkha is this year&rsquo;s hot sophomore commodity, and to compensate for a disadvantage in maturity, he gets an 11&#45;pound weight break (133 to 122) from older horses like Time Test.The Gurkha, trained by Aidan O&rsquo;Brien, races beyond a mile for the first time in the 1 1/4&#45;mile Eclipse. He was the strong favorite to win the St. James&rsquo;s Palace Stakes at Royal Ascot on the heels of an impressive win in the French 2000 Guineas but wound up trapped near the back of the field behind a mild pace and could not get to the victorious Galileo Gold, who got the jump. By Galileo, The Gurkha figures to stay the trip, and the good&#45;to&#45;soft conditions he&rsquo;ll find Saturday are well within his range.Time Test, the Roger Charlton&#45;trained Juddmonte colt, would prefer something firmer, but the Sandown course is not too wet for him to make an appearance. Time Test, who gets a rider change to Pat Smullen with Ryan Moore riding The Gurkha, floundered on the sodden autumn course at Keeneland in the Breeders&rsquo; Cup Mile but was a course and distance winner in capturing the Brigadier Gerard in his only start this year at age 4. My Dream Boat scored a major upset in rallying late to win the Group 1 Prince of Wales&rsquo;s Stakes at Royal Ascot earlier this month but must prove that that showing was not a fluky result over soft ground he handled better than his more accomplished rivals. Hawkbill, a Godolphin 3&#45;year&#45;old, was supplemented into the Eclipse on the strength of his recent win in the Tercentenary Stakes during the Royal Ascot meeting.Post time for the race is 10:45 a.m. Eastern.
