INGLEWOOD, Calif. (AP) -Acclamation, a 14-1 long shot, opened a huge early lead and was never challenged Saturday in a 7 1/2-length victory, the biggest in the history of the $150,000 Jim Murray Memorial Handicap at Hollywood Park.

Ridden by apprentice jockey Christian Santiago Reyes, who had never won a graded stakes, Acclamation led by as many as 10 lengths early and yielded little ground as he covered 1 1/2 miles on turf in 2:26.59.

The 4-year-old colt also became the first California-bred to win in 20 runnings of the Grade II race, named for the Pulitzer Prize-winning Los Angeles Times sports columnist.

Acclamation paid $31, $12.40 and $6.80. Falcon Rock paid $5.60 and $3.60, and Rendezvous was a neck back in third and paid $3.60 to show.

``I wasn't planning on going to the front, but everybody took back so I just inherited the lead,'' Reyes said through an interpreter. ``I had never been on him before, so I wasn't sure what to expect. At the half-mile pole, I still had not let him run, he was just galloping along.''

Reyes won three races on the day.

The clear favorite Scintillo, making his first U.S. start for trainer Neil Drysdale, was pulled up by rider Rafael Bejarano, who said he was worried the horse had hurt his hind end.

Trained by Don Warren for owners and breeders Buddy and Judy Johnston, Acclamation won for just the third time in 18 lifetime starts, and had yet to finish better than third in five starts this year. The $90,000 winner's share of the purse increased the colt's earnings to $347,048.
