LOUISVILLE, Ky. - Cobalt Blue and Xchanger dropped out of Kentucky Derby consideration yesterday, opening the door for Teuflesberg and Imawildandcrazyguy to run on Saturday.

The field is limited to the 20 horses with the highest earnings in major stakes races. Teuflesberg ($122,942) and Imawildandcrazyguy ($104,000) were ranked 21st and 22nd.

Entertainer Merv Griffin took his colt out of the running, citing Cobalt Blue's seventh-place finish in the Illinois Derby and a recent subpar workout at Keeneland.

"I've just been unhappy with a few of the things that have happened to him," Griffin said by telephone.

Trainer Doug O'Neill still has two Derby horses: Great Hunter and Liquidity.

Griffin had a similar disappointment last year when Stevie Wonderboy missed the Derby with a small fracture in his right front leg.

Trainer Mark Shuman told Churchill Downs officials that Xchanger was out of the race. Their places are taken by two inexpensive horses.

Teuflesberg, a $9,000 yearling purchase, most recently was fourth in the Blue Grass Stakes after setting the pace. Trainer and co-owner Jamie Sanders got a welcome call from O'Neill.

Imawildandcrazyguy, a $17,000 yearling purchase, gives trainer William Kaplan two Derby horses. He also will send out Storm In May, who is blind in one eye and cost $16,000 at the yearling sales.

Entries close this morning, with post positions chosen today at 5 p.m. *
