Already at Arlington 2011, Stidham is at it again. His barn won last Saturday&rsquo;s Hanshin, the season&rsquo;s first graded race, with Workin for Hops, and it has two more apparently live runners in a pair of open stakes Saturday, Willcox Inn for the $100,000 Arlington Classic and Upperline in the Grade 3, $100,000 Arlington Matron.\r\nBoth Saturday races drew large, competitive fields, with 12 3-year-olds turf hopefuls in the 1 1/16-mile Classic, first leg of Arlington&rsquo;s Mid-America Triple, and 10 entrants in the Matron, a 1 1/8-mile Polytrack race for fillies and mares.\r\nUpperline had a productive winter in New Orleans, scoring two smart turf-stakes wins and looking especially sharp in the Bayou Handicap, where she rolled to a four-length victory in a fast time. But Upperline failed to reproduce that performance May 7 at Churchill, finishing last of nine &ndash; albeit fewer than five lengths behind victorious Aviate &ndash; in the Grade 2 Distaff Turf mile. Stidham could find no ready excuse for the disappointing effort, but Upperline seems to her trainer to be maintaining the form she showed at Fair Grounds.\r\n&ldquo;She had a superior work on Sunday,&rdquo; Stidham said, referring to a half-mile drill in 47.20 seconds. &ldquo;She definitely gave me the thumbs-up.&rdquo;\r\nThe move to 1 1/8 miles on Polytrack also seems positive. Upperline won the Arlington Oaks under such conditions last summer, and has 3 wins and 1 second from 5 synthetic-surface starts.\r\nThere are potentially worthy rivals in the Matron, particularly Pachattack, English trainer Gerard Butler&rsquo;s fifth starter at the meet. Butler&rsquo;s six-horse American satellite string swung into action last weekend with a win and a place in four tries, and Pachattack has the chops to factor in the Matron. She was a subpar ninth in a Group 3 at Newmarket on May 1, but started her year finishing a solid thirdfacing males in the March 26 Winter Derby over Lingfield&rsquo;s all-weather surface. Last fall, after a troubled sixth in the Beverly D. and a decent fifth in the E.P. Taylor &ndash; both Grade 1&rsquo;s &ndash; Pachattack walloped seven rivals in the $186,000 Maple Leaf, a 1 1/4-mile Polytrack race at Woodbine. A similar performance would make things tough on Upperline in the Matron. Others to consider are Milwaukee Appeal, who is struggling to regain competitive 2010 form, and Satan&rsquo;s Quick Chick, who was no match for Pachattack in the Maple Leaf.
