A deep, talented and highly competitive field of 11 older horses was assigned posts for Sunday's 18th edition of the $1,000,000 Pacific Classic at a gala draw party conducted Wednesday evening at The Lodge at Torrey Pines, the deluxe resort hotel along the coast south of Del Mar racetrack.

The lukewarm favorite in the Grade I mile and a quarter that is the Del Mar Thoroughbred Club's centerpiece event is the Eastern invader Go Between, who'll carry a morning line of 3-1 and break from Post 6 in the well-matched lineup. Hall of Fame trainer Bill Mott shipped his charge to Southern California for the fourth time this year and once again commissioned the saddle services of the 2007 Eclipse Award-winning rider Garrett Gomez for his Pacific Classic run.

The Pacific Classic will be one of four major stakes on the Sunday program that are part of the Breeders' Cup Challenge "Win and You're In" program. All four will be televised on ESPN2 on a two-hour program that will be offered from 5 to 7 p.m. (PDT).

The three other stakes are the $400,000 Del Mar Mile, the $300,000 Pat O'Brien Handicap and the $200,000 Rancho Bernardo Handicap.

The Grade II Mile drew a field of 11 headed by morning-line favorite Daytona (5-2). Alex Solis will ride the Irish-bred speedster for trainer Dan Hendricks as they break from Post 8.

The Grade II Pat O'Brien drew a field of 12 topped by 2007 Sprint champion Midnight Lute, who is listed at 9-5 in the morning line. Gomez also has the call on the giant-sized colt who is trained by Bob Baffert in the seven-furlong feature and they'll break from Post 3 on Sunday.

The Grade III Rancho Bernardo has lured 10 female sprinters with the flashy filly Magnificience the morning-line choice at 3-1. David Flores will get a leg up from trainer Bruce Headley in the six and a half-panel spin as they come out of Post 3.

Sunday's 11-race card will have a first post of 2 p.m. The four stakes will go in order as Race 7 (Rancho Bernardo), Race 8 (Pat O'Brien), Race 9 (Mile) and Race 10 (Pacific Classic). Post time for the Pacific Classic is slated at approximately 6:40.

Del Mar will have a guaranteed $1-million Pick Six and a guaranteed $500,000 Pick Four on the program.
