ARLINGTON HEIGHTS, Ill. - Since it cost $5,000 to pre-enter for the race by midnight last Friday, the field for Saturday's Arlington Million has all but been assembled, a nine-horse group with Gio Ponti the likely favorite over Einstein. Final entries will be taken and post positions assigned for the Million as well as Saturday's other two Grade 1 turf races, the Beverly D. and the Secretariat, on Tuesday afternoon. And none of these details should have one bit of influence over how the Million will unfold: Presious Passion will be out there on the lead, winging it.
