HOT SPRINGS, Ark. &ndash; The $75,000 Prima Donna for 3-year-old fillies at six furlongs at Oaklawn on Saturday is something of a springboard to different distance goals for leading contenders Gran Lioness, who was third in last month&rsquo;s Grade 3 Rachel Alexandra, and Arienza, a daughter of Horse of the Year Azeri.\r\nIn all, a field of eight will go, including stakes-winning sprinter Lady Giacamo.\r\nGran Lioness is turning back from 1 1/16 miles. She set the pace to the late stages in the Rachel Alexandra at Fair Grounds in her last start Feb. 19. The race came following a front-running win in the $200,000 My Trusty Cat at seven furlongs at Delta Downs on Jan. 14. The turnback Saturday is a harbor of things to come for Gran Lioness.\r\n&ldquo;We thought that about a mile is all she wants and we&rsquo;re kind of thinking seven-eighths is probably her ideal distance,&rdquo; said Bret Calhoun, who trains Gran Lioness for Wayne Sanders and Larry Hirsch. &ldquo;We&rsquo;ve mapped out a schedule to back her up to six furlongs, then head to Keeneland to go seven-eighths in the Beaumont.\r\n&ldquo;She&rsquo;s proven pretty good sprinting, and she&rsquo;s all right two turns, but I think at a mile or less. I&rsquo;m pretty excited about running her Saturday.&rdquo;\r\nCliff Berry has the mount on Gran Lioness, who in the My Trusty Cat earned one of the year&rsquo;s best Beyer Speed Figures for a 3-year-old filly, a 97.\r\nArienza was a smashing debut winner at Oaklawn on March 6, when she defeated older horses in a maiden special weight. Arienza covered six furlongs in 1:10.40 and earned a Beyer of 83. In time, her connections would like to give her a shot at two turns, perhaps in the Grade 2 Fantasy or the Instant Racing, both run next month at Oaklawn.\r\n&ldquo;The two-turn stuff is all down the road,&rdquo; said trainer Dan Peitz, &ldquo;but one would assume being by Giant&rsquo;s Causeway and out of Azeri, that two turns should be what she really likes. We&rsquo;ll see how she runs and how she comes out of it.&rdquo;\r\nArienza faces a test Saturday, with one of her challenges being her inexperience.\r\n&ldquo;I&rsquo;m assuming we&rsquo;re going to be in with a bunch of fillies that have run a bunch of times, that just have that experience,&rdquo; Peitz said. &ldquo;We obviously have a world of ability. Now, we&rsquo;re getting some experience.&rdquo;\r\nTerry Thompson has the mount for owners Robert and Lawana Low.
