ARLINGTON HEIGHTS, Ill. - Willcox Inn is two-thirds of the way to a sweep of Arlington's Mid-America Triple, and leg 2, Saturday's American Derby, was no contest.\r\nSweeping to the front more than a half-mile from home, Willcox Inn held a four-length lead at the stretch call and a four-length lead at the finish, easily holding clear the stretch run of second-place Suntracer. Derby Kitten finished third, Chalice fourth. Willcox Inn, who paid $6.20 to win as the favorite, was timed in 1:54.56 for 1 3/16 miles on firm, fast-playing turf, a stakes record. The performance figures to make Willcox Inn one of the top choices in the Grade 1 Secretariat Stakes here Aug. 13.\r\nWillcox Inn won the May 28 Arlington Classic, the first race in Arlington's series of 3-year-old grass races, by 2 1/2lengths, but that was more of grind-it-out type run over a wet turf course Willcox Inn might not have favored.\r\n&quot;He won over the softer turf even though he didn't love it,&quot; said trainer Mike Stidham. &quot;Today, he loved it.&quot;\r\nThe Grade 2, $200,000 American Derby, unfolded somewhat strangely thanks to Zoebear, who essentially ran off in the early going. Willcox Inn raced in third as Zoebear opened a nine-length lead down the backstretch, passing the half-mile in 47.55 seconds before suddenly slowing his pace. In less than a furlong Zoebear's big lead had evaporated and Willcox Inn made the front, staying on impressively the last half-mile. But was the early part of Willcox Inn's American Derby that struck jockey Robby Albarado.\r\n&quot;I was doing it so easy that first half-mile,&quot; Albarado said. &quot;The best part was the way he settled.&quot;\r\nWillcox Inn, who beat Kentucky Derby winner Animal Kingdom in his career debut on Arlington Polytrack last summer, now has won three of seven starts, and is 2-1-1 from 4 turf races. Owned by eight partners, Willcox Inn is a son of Harlan's Holiday out of De Aar bred by Dr. John Chandler and purchased as a yearling for $50,000.
