For the first time in 31 racing programs, a bettor solved the 20-cent Rainbow 6 for a jackpot payoff of $399,545.94 on Sunday at Laurel Park . Soft Landing ($10), co-owned by Span Investments and trainer Jose Corrales , was one of three horses to take down the jackpot heading into the ninth-race finale, winning the 51/2-furlong maiden claimer for fillies and mares to complete the 6-7-6-5-8-2 combination. The winning ticket was purchased through Maine off-track-betting. Other winners in the sequence were Private Tutor ($109.80) in the fourth race, Emma'sdiamonddiva ($5.80) in the fifth, Versed ($8) in the sixth, Nyx Warrior ($6.80) in the seventh and Rocket Heat ($6.20) in the eighth. A total of $67,064 was bet into the multi-race wager Sunday, adding to a Maryland state-record carryover of $345,898.33 from Saturday's program. The Rainbow 6 begins anew when live racing returns to Laurel on Friday, spanning races 5-10. On Saturday, Laurel will host its Spring Stakes Spectacular program, featuring five stakes worth $550,000 in purses led by the $125,000 Federico Tesio for 3-year-olds and $125,000 Weber City Miss for 3-year-old fillies, 'Win and You're In' events for the $1.5 million Preakness on May 19 and $250,000 Black-Eyed Susan on May 18, respectively, at Pimlico Race Course.
