ARLINGTON HEIGHTS, Ill. - It has happened again. Lewis Michael has turned in a top performance when it mattered least. Not that winning a high-end allowance race on Sunday at Arlington was meaningless, but the winner's share of a $37,500 purse pales in comparison to the money Lewis Michael could earn if he merits a career at stud. That's not so far-fetched, either, since Lewis Michael is in general from a good family, and in particular a full brother to champion filly Dreaming of Anna.
