ELMONT, N.Y. - Nehro, the second-place finisher in the Kentucky Derby, completed his preparation for Saturday's Belmont Stakes with a four-furlong drill in 50.85 seconds early Monday morning at Belmont Park. Nehro came onto the track about 6:45 a.m. and, accompanied by a pony, jogged the wrong way from an area near the 1 1/4-mile start to the finish line of the 1 1/2-mile oval. Then, going it alone, Nehro jogged off the right way before breaking into his work at the half-mile pole. He remained well off the rail through fractions of 13.18 seconds for the opening furlong and 25.74 seconds for a quarter-mile. He went out five furlongs in 1:03.97. All times were clocked by David Grening of Daily Racing Form.   BELMONT STAKES: Replays, contenders, and news updates »
