After making her first three starts on the Golden Gate Tapeta surface, Seismic Speed may reveal her hole card in the fifth race there Wednesday. Seismic Speed makes her grass debut in the one-mile maiden special weight race for 2-year-old fillies, and as a daughter of a turf stakes winner, she is bred to excel on the surface.\r\nSeismic Speed is by Gone West and out of the A.P. Indy mare Shake Off, who made 12 of her 13 starts on turf. She won a Hollywood maiden race in her debut, a Santa Anita optional claimer in her third start, and, in perhaps her best performance, won the 2004 Barona Cup Handicap on the Del Mar turf.\r\nShake Off did her best running going long, and her daughter could use a shot of that stamina. Seismic Speed has shown speed in each of her starts, finishing second and fourth in a pair of sprints to begin her career and then second to Lilacs and Lace after making the pace going a mile last out.\r\nWith those strong performances behind her, the Jerry Hollendorfer-trained Seismic Speed figures to be strongly bet Wednesday, when she will be ridden for the third straight time by Leslie Mawing.\r\nAmong Seismic Speed&rsquo;s five opponents is Under Wraps, who has been sent north from Hollywood Park by trainer Richard Mandella and will be ridden by Russell Baze.\r\nUnder Wraps has a little breeding of her own: She&rsquo;s a Dixie Union half-sister to Meadow Breeze, who upset the Grade 1 Matron at Belmont in 2006. It&rsquo;s unclear, however, how much Under Wraps will benefit from the surface and distance of Wednesday&rsquo;s race.\r\nIn her only start, Under Wraps showed speed and tired to fifth in a maiden sprint at Del Mar 2 1/2 months ago. Under Wraps&rsquo;s dam, Unacloud, never raced, and her half-sister Meadow Breeze finished sixth and ninth in her two starts going longer than seven furlongs, and never raced on grass.\r\nAlso in the field are Hoosier Honey, who comes off a second in a maiden sprint on the Golden Gate Tapeta; Opening Night, a Theatrical filly making her debut; Campeenya, second last out on the Golden Gate turf in a maiden claimer; and Perfect Gleam, who had traffic trouble in her last start, a third in a maiden claiming sprint.\r\n◗ The only other non-claiming race on the Wednesday card is the first, which is a maiden special weight sprint for fillies and mares.
