Pica Slew was an exceptionally fast filly at 3 last year, a season that included two stakes wins at Calder, notably the Grade 3 Azelea Stakes.\r\nAfter an eighth as the 7-2 favorite in the Grade 1 Test Stakes at Saratoga last August, a race in which she led early and faded, Pica Slew was sent to trainer John Shirreffs. The filly makes her first start for Shirreffs in Sunday&rsquo;s $250,000 Santa Monica Stakes over seven furlongs.\r\nShirreffs does not expect Pica Slew to be wildly fast for her California debut.\r\n&ldquo;She always works behind another horse,&rdquo; Shirreffs said. &ldquo;I&rsquo;d be surprised if she&rsquo;s on the lead.&rdquo;\r\nOwned by Terra Di Sienna Stable, Pica Slew has won 3 of 5 starts. Shirreffs is her fourth trainer. She was trained by Greg De Gannes at 2, and by Joseph Calascibetta and Mike Hushion at 3.\r\nPica Slew is part of a Santa Monica field led by Switch, the winner of the Grade 1 La Brea Stakes over seven furlongs on Dec. 26. Other expected starters are Mother Ruth and Gilded Gem, the first two finishers of the Kalookan Queen Handicap on Jan. 7; and Sweet August Moon, the winner of the Rancho Bernardo Handicap last August.
