Ferdinand, the 1986 Kentucky Derby winner, won his first race as a 4-year-old after six straight defeats with a 1 1/4-length victory yesterday in the $500,000 Hollywood Gold Cup at Hollywood Park in Inglewood, Calif.

Ridden by Bill Shoemaker, Ferdinand ran down stablemate Judge Angelucci in the stretch and drew clear in the final yards.

Judge Angelucci finished in a dead heat for second with Tasso. Ferdinand raced 1 1/4 miles over a fast track in 2:00 3/5.

Canterbury Downs:

Front-running favorite Lost Code led from wire to wire and won the $300,000 St. Paul Derby by 1 1/4 lengths over Proudest Duke at the track located near Minneapolis.

The victory was the sixth straight for Lost Code, who was ridden by Gene St. Leon and earned $180,000 for owner Donald Levinson of Baltimore.

Proudest Duke, a 15-to-1 shot, made a late charge to take second in the the 1 1/8-mile race for 3-year-olds. Locally based Staff Riot finished third in the field of eight.

Lost Code, who went the distance in 1:49 2/5, paid $4.40. Cryptoclearance, the 7-to-5 second choice, finished fifth.

Laurel:

Randy Romero guided Doubles Partner through close quarters entering the home stretch, then urged his mount to a 3 1/2-length victory over 40-to-1 long shot Yampacala in the $56,350 Pearl Necklace Stakes for 3-year-old Maryland-bred fillies. It was another four lengths back to Miss Cee Gee in third.

Doubles Partner had run against top company at Belmont Park and was made an 11-to-10 favorite by the crowd of 10,205. The daughter of Damascus ran the 1 1/16 miles over a firm turf course in 1:43 4/5.

Earlier, the Maryland racing stewards, after an investigation of several days, found nine jockeys blameless of any violation of the racing rules when they voted unanimously to cancel last Monday's 10th race because of unsafe track conditions.

Charles Town:

Philip Grove moved to within four victories of the 3,000 career win mark by riding five winners over the weekend. The Frederick native has mounts in five of tonight's nine races.
