The field for Saturday's 34th running of the Washington, D.C. International at Laurel was reduced to 12 yesterday when Mourjane and Triptych were withdrawn from the 1 1/2-mile turf classic.

Win, the overnight favorite at 5 to 2, did not do well in the draw for post positions, landing the No. 12 spot, which became No. 11 because of the scratches.

The son of Barachois also may be hampered by a turf course that will be less than hard. Sally Bailie, his owner-trainer, has said that her charge needs a hard track to do his best.

Robert Migliore, Win's rider in his last six races, will again be aboard.

Strawberry Road II, coupled in the entries with Bob Back, also drew an outside post, the No. 10 position. Strawberry Road II will be ridden by Angel Cordero, who will be aboard the Australian-bred for the first time. Strawberry Road II is listed at 3 to 1.

Patrick Biancone, trainer of Strawberry Road II, said, "In a mile-and-a-half race, the post position is not especially important. I see no problems with that."

Yashgan, the third choice at 5 to 1, drew the No. 7 post, which became No. 6 when Triptych scratched.

Trainer John Sullivan said of Yashgan, "He did do his best running while on the inside in his last race (the Oak Tree Invitational Handicap) but he can run from anywhere. His rider, Chris McCarron, knows his way around the Laurel course."

The International is worth $400,000 this year, a rise of $150,000 over 1984.
