Jockey Patrick Valenzuela, winner of last year's Kentucky Derby aboard Sunday Silence, was suspended for six months by the Board of Stewards at California's Hollywood Park.

Valenzuela initially was placed on indefinite suspension after failing to honor his riding assignments at Santa Anita Nov. 3. The suspension is retroactive to Nov. 12 and will be in effect until May 11.

The board also placed the 28-year-old on probation for two years, during which he "shall remain in a rehabilitation program satisfactory to the California Horse Racing Board and stewards."

Last year, Valenzuela was suspended for 60 days for cocaine use. His mounts earned more than $8.2 million last year, ranking him ninth in the nation. . . .

Double Bunctious led all the way, splashing to a six-length upset in the 21st running of the $75,000 All Brandy Handicap at Laurel Race Course.

Double Bunctious, who was clocked in 1:52 4/5 for the 1 1/8 miles over a muddy track, was ridden by Mario Pino, who picked up the mount midway through the program.

Mymet finished second in the field of eight Maryland-bred fillies and mares and Ismelda was third. Thirty Eight Go Go, the 11-10 favorite, was fifth.
