ARLINGTON HEIGHTS, Ill. – Alternation, winner of Peter Pan Stakes at Belmont, worked a solid six furlongs on Friday morning at Arlington Park, trainer Donnie Von Hemel’s summer base. Von Hemel said later in the morning that he and Alternation’s owner, Josephine Abercrombie’s Pin Oak Stable, won’t firm up plans for the colt’s next race until sometime this weekend. Alternation is being considered for a return trip to New York for the Belmont Stakes.
