A 3 1/2-length win in the Grade 3 Aristides Stakes at Churchill Downs two starts ago and a $1 million bankroll are sufficient reasons to stamp Delaunay as the favorite in the Sen. Robert Byrd Memorial Stakes, one of five $100,000 dirt sprint stakes on the West Virginia Derby undercard Saturday at Mountaineer. But given that the 7-year-old Delaunay could do no better than fourth when he ran in this same six-furlong race two years ago, and the horses he beat in the Aristides went 0 for 5 in their next starts, it might be worthwhile to search for a better price in the 12-horse field. Viable options include Star Harbour, who won locally by nearly seven lengths with a 99 Beyer Speed Figure a month ago, and Res Judicata, 2 for 2 to launch his 4-year-old campaign. Russell Road, elevated to first via disqualification in last year’s Byrd, and longshot Lucy’s Bob Boy are expected to scratch in favor of a $30,000 allowance Friday night at their home track, Charles Town. :: West Virginia Derby: Get PPs, watch Saturday's card live Byrd Memorial Stakes (Race 6) Key contenders Delaunay (Last 3 Beyers: 102-99-90) Formulator Facts: Trainer Tom Amoss is 1 for 10 shipping to Mountaineer for stakes.
