Baffert to sit out Kentucky Derby
Veteran trainer Bob Baffert says he is unable to enter a competitive horse in the Kentucky Derby.

BOB BAFFERT won't be saddling a horse in Saturday's Kentucky Derby for the first time since 2008.
The Hall of Fame trainer said yesterday that Govenor Charlie would not run. His other possibility, Code West, also won't compete in the Derby at Churchill Downs.
Sunland Derby winner Govenor Charlie was 11th on the points leaderboard that determines the 20-horse field for the 1 1/4-mile race. Code West was ranked 21st.
Baffert hasn't been on the Derby sidelines since 2007 and '08. He has won the race three times, but not since 2002.
Govenor Charlie galloped yesterday for the first time since April 11, a layoff caused by a foot bruise and soreness in his hind end.
"You cannot have any kind of hiccup," Baffert said. "We want to be competitive and if you're not competitive, my clients don't want to be in there. We're just going to watch and good luck to everybody else."
Baffert said Govenor Charlie could be pointed toward the May 18 Preakness, while Code West is a possibility for the Belmont Stakes on June 9.
