Five of the top 17 pacers in the U.S. Trotting Association's experimental championship ratings were entered yesterday for Saturday's $100,000 William E. Miller Memorial at Rosecroft Raceway.

Temujin, ranked third in the experimental ratings with a potential for a 1:53 mile, and Apollo's Way, ranked eighth at 1:54, are expected to be the favorites for Maryland's first $100,000 standardbred race. The other horses entered with top experimental ratings are No. 12 Soky's Atom; No. 14 Rabbit Road, owned by Winnipeg Jets hockey player Serge Savard, and No. 17 Solid Fuel, part of a Shelly Goudreau-trained entry with Apollo's Way.

Latrobe Deke, owned in part by golfer Arnold Palmer, also is entered.

None of the favorites drew good post positions. Apollo's Way, scheduled to be driven by Goudreau, drew the outside No. 8 position in the first tier, just inside of stablemate Solid Fuel. Temujin, whose driver is listed as 1981 national money-winning champion William O'Donnell, drew No. 11, third from the rail in the second tier of four horses.
