Hollywood Park, Del Mar open their doors to Oak Tree Racing Assn.

If the company that runs Santa Anita can’t make a deal with the nonprofit Oak Tree Racing Assn. to run its annual fall meeting at the Arcadia track, then Hollywood Park and Del Mar are prepared to offer their facilities, executives at both tracks said Saturday.

Jack Liebau, president of Hollywood Park, said his track has made an offer to open its facility “rent free” to Oak Tree. And Joe Harper, president of Del Mar, said, “Of course we would be open to running their meet at Del Mar.”

MI Developments, the company that owns Santa Anita, voided a contract with Oak Tree last week. Oak Tree has run its meet at Santa Anita since 1969, and the contract was supposed to run through 2016.

“Oak Tree has done a lot of good things for the industry and should have an alternative if they can’t work things out” with Santa Anita, Liebau said.

Santa Anita previously was owned by Frank Stronach’s Magna Entertainment Corp. but has been in bankruptcy proceedings. Stronach still controls the track and has been complaining about the way racing is run in California.

Discussions about Oak Tree are on the agenda for Thursday’s meeting of the California Horse Racing Board at Golden Gate Fields.

A record victory

Acclamation, sent off at odds of nearly 15-1, came away with the largest margin of victory in the 20-year running of the $150,000 Jim Murray Memorial Handicap, beating second-place Falcon Rock by 7½ lengths in the 1½-mile turf marathon at Hollywood Park.

Acclamation, a 4-year-old son of the prolific California sire Unusual Heat, became the first California-bred horse to win the race. Jockey Christian Santiago Reyes, a 20-year-old apprentice who loses his weight allowance after Sunday’s races, sent Acclamation to the lead from the start, opening a 10-length advantage down the back stretch.

“I wasn’t planning on going to the front, but everybody took back, so I just inherited the lead,” Santiago Reyes said through an interpreter.

It was day for upsets at Hollywood Park, including the seventh race, when a win by 34-1 longshot Fortunate Victory helped trigger a record $1 trifecta payoff of $78,703.90.
