ARLINGTON HEIGHTS, Ill. &ndash; Alternation, winner of Peter Pan Stakes at Belmont, worked a solid six furlongs on Friday morning at Arlington Park, trainer Donnie Von Hemel&rsquo;s summer base. Von Hemel said later in the morning that he and Alternation&rsquo;s owner, Josephine Abercrombie&rsquo;s Pin Oak Stable, won&rsquo;t firm up plans for the colt&rsquo;s next race until sometime this weekend. Alternation is being considered for a return trip to New York for the Belmont Stakes.\r\nBELMONT STAKES: Replays, contenders, and news updates &raquo;\r\nWorking alone under jockey Eddie Razo around 6:30 a.m. Friday, Alternation was timed by Arlington clockers in splits of 37.60 seconds for three furlongs and 49 seconds for a half-mile on the way to a five-furlong final time of 1:00.60. Alternation then galloped out six furlongs in a strong 1:13.\r\n&ldquo;I was very pleased,&rdquo; Von Hemel said. &ldquo;He broke off real nice and relaxed, and basically every eighth was faster than the previous one. He finished well, galloped out really good.&rdquo;\r\nThe workout was Alternation&rsquo;s first since he won the Peter Pan on May 14. Coming back from New York, Alternation stopped for a layover at Pin Oak in central Kentucky before arriving at Arlington on May 18. Von Hemel said Alternation had taken the shipping well. \r\n&ldquo;He was a real trooper on that,&rdquo; said Von Hemel. &ldquo;He never got off his feed, never looked like he was down about it or anything.&rdquo; \r\nAlternation, by Distorted Humor, won three races in a row over the winter. He flipped in the starting gate before the March 19 Rebel Stakes and was scratched, and finished a troubled fifth in the Arkansas Derby before scoring his first stakes win in the Peter Pan.
