Terrain and West Side Bernie, who last raced in the Breeders' Cup Juvenile, were among 17 horses pre-entered on Friday in the Grade 3, $750,000 Delta Jackpot at Delta Downs. The 1 1/16-mile race for 2-year-olds will be limited to a field of 10 when it is run on Delta's six-furlong track Dec. 5. Final entries for the race will be held Dec. 2.\nDelta also took pre-entries on Friday for the Grade 3, $500,000 Delta Princess, for 2-year-old fillies at one mile. Among the 15 who were pre-entered were Grade 3 winners Livin Lovin and C.S. Silk. The race will also be run Dec. 5, with final entries to be taken Dec. 2.\n"I think in both races, especially the boys' race, we got an exceptional bunch this year," said John Simon, the racing secretary at Delta. \nTerrain finished fourth, beaten 2 1/4 lengths by Midshipman, in the Juvenile. He came into the race off a runner-up finish in the Grade 1 Breeders' Futurity at Keeneland. West Side Bernie was sixth in the Juvenile, one start after winning the Grade 3 Kentucky Cup Juvenile at Turfway Park.\nBoth horses will get into the field based on starting preferences, with Kick On, the winner of the $150,000 Jean Lafitte at Delta, getting first preference because he captured that local prep for the Jackpot. The next preference is for horses who have finished first, second, or third in graded stakes, while the third preference is earnings.\nBig Drama leads all pre-entered Jackpot horses in earnings with $410,250. Others expected to be able to get into the race include Skipadate, the runner-up in the Grade 3 Summer at Woodbine; Retap, second in the Kentucky Cup Juvenile; and stakes winners Trinity Magic and Valid Message.\nThe Delta Princess field is expected to also include Southern Yankee, who won the local prep for the race, and stakes winners Just Jenda, My Spanx, Ten Churros, and Seacrettina.\nIt cost $1,000 to pre-enter horses on Friday.
