Waya and MacDiarmida, two American horses, were made 5-to-2 and 3-to-1 favorites on the morning line yesterday for the Washington, D.C. Internationa, to be run Saturday at Laurel Race Course.
Waya's selection stems from her four-race win streak, including victories over top male rivals in the Man O War and Turf Classic, said oddsmaker Earl Hart.
MacDiarmida's selection is based on his record of 11 victories in 12 turf starts this year.
Tiller, another U.S. representative, was established for Saturday's race as the third choice in the field of eight at 7 to 2.
Trillion and Frere Basile, the two French challengers, were installed at 5 to 1 and 8 to 1, respectively.
Italy's Stone was listed at 10 to 1 as was the Canadian challenger, Overskate.
Noble Dancer II was made the outsider at 20 to 1.
Frere Basile galloped around the Laurel strip yesterday despite having been given an antibiotic on Monday. The horse was suffering from a persistent cough that raised his temperature to 102, two points above normal. The French import showed no temperature yesterday.
Stone, Italy's hope in the $200,000 classic, was galloped once around the turf course. His trainer, Luigi Turner, said after the gallop, "Stone ran a fortnight ago and doesn't need much work. He'll have a bit of a faster work on Thursday."
Noble Sancer II breezed seven eights in 1.27 2/5 over the turf.
