MIAMI - The graded stakes winner Jet Propulsion went nearly nine months between victories before rallying to win a money allowance race here on Oct. 10. On Saturday, he will try to come back in just two weeks and do it again when he takes on similar opposition going 1 1/16 miles on the grass in a $29,500 allowance.\nJet Propulsion, winner of the Grade 3 Miami Mile Breeders' Cup in 2007, had always been at his best when racing on the lead. But the former claimer, who couldn't win under a $10,000 price tag here nearly four years ago, showed a new dimension by rallying from off a fast and very contentious pace to a decisive 2 1/4-length victory over Pickapocket going 7 1/2 furlongs in his last start.\nPerhaps the biggest obstacle to Jet Propulsion posting a second consecutive victory will be the weather. Steady rains forced the races to be taken off the grass on Thursday, and should the same conditions prevail on Saturday, he would in all likelihood be scratched since he's not raced on dirt in over three years. \nJet Propulsion, a 6-year-old son of Double Honor, is trained by Donna Green for owner Dennis Punches. Jet Propulsion will be ridden by Eibar Coa, who will likely look to take him back off the lead once again with speedsters Cinnamon Road, Rexson's Rose, and Pechito in the field.\nCinnamon Road, the lone 3-year-old in the lineup, has also done his best when loose on the lead. Capable on both turf and dirt, Cinnamon Road was awarded a victory following the disqualification of Temos Dream in the Needles Stakes on Sept. 26. He has not started on grass since attempting to rate off the lead and finishing a tiring fifth in the American Dreamer Stakes on July 11.\nPickapocket, who will be ridden for the first time by Coa's cousin Daniel Coa, rallied from nearly a dozen lengths off the pace to finish second behind Jet Propulsion in his first start in better than six months. Trained by Marty Wolfson, Pickapocket will attempt to break a nine-race losing streak that dates back to April 12, 2008 at Keeneland.\nWolfson will also send out the late-running Cristobal under Kristi Chapman. Cristobal finished four lengths behind his stablemate Pickapocket and nearly seven lengths behind Jet Propulsion when checking home fourth two weeks ago.\nWet opener to Tropical meet\nThe Tropical at Calder meeting got off to a soggy start on Thursday with wet weather putting a damper on the proceedings. The day-long showers also forced both scheduled turf races to be switched to the main track, resulting in 11 of the 25 horses entered for those two races to be scratched.\nJockeys Javier Santiago, Manoel Cruz, and Wesley Henry Sr. each won two races on opening day. \nw Stakes winner Seaside Affair continues to train smartly for her return. Winner of Del Mar's Torrey Pines Stakes as a 3-year-old in 2007, Seaside Affair breezed a half-mile in a bullet 48.60 and galloped out five furlongs in 1:01.80 over a wet-fast track on late Thursday morning. Seaside Affair has not started since finishing far back in an allowance race here on May 24.
