Contrarity, making her career debut, led all the way for a front-running, half-length victory in the first juvenile race of the season Saturday at Laurel Park. A daughter of Yesbyjimminy, ridden by Katie Davis for trainer Hugh McMahon and owner Danny Limongelli, Contrarity ran 41/2 furlongs in 53.36 seconds in the $40,000 maiden special weight sprint. Sent off at 15-1, Contrarity returned $32 to win. G's Treasure, Cotton Eye Girl, Sammy Be Cool, Pauline's Raven and She Runs Hot completed the field. ... Hillwood Stable's Shimmering Aspen cruised to her third consecutive victory in Saturday's featured eighth race, an impressive front-running performance that may land her in stakes company for her next start. Shimmering Aspen ($3.80) was never threatened from her rail post under a hand ride from jockey Steve Hamilton, drawing off effortlessly in the stretch to win by seven lengths in 1:23.25 for seven furlongs. The Malibu Moon filly was favored at 4-5 in the $45,000 second-level optional claiming allowance, her second straight win against older horses.
