INGLEWOOD, Calif. – The Oak Tree at Hollywood Park meeting will run an additional day on Wednesday, Oct. 27 to make up for the rainout on Wednesday of this week, the track announced Thursday. Hollywood Park canceled its eight-race Wednesday program after a significant downpour in late morning led to erosion in two places on the backstretch. The decision to cancel races was made at 1:34 p.m., a half-hour after the scheduled start to the program. Approximately 1.25 inches of rain fell in about an hour before lunch, according to track officials. An area near the five-furlong pole, adjacent to a path between the barns and the racetrack, was the section of principal concern. Track officials said water ran down the path and collected on the racetrack during the rainstorm. Track maintenance crews worked on the surface through lunchtime and into early afternoon to salvage the race card on Wednesday, which had a start time tentatively pushed back to 1:40 p.m. By 1:30 p.m., it was apparent that racing would not go forward, since the horses for the first race had not been sent to the paddock. Oak Tree received a waiver from the California Horse Racing Board on Thursday to add the Oct. 27 program. As a result, the track will offer five days of racing that week, the final week of the Oak Tree at Hollywood Park meeting, which ends Oct. 31. Hollywood Park will begin its own fall season on Thursday, Nov. 4. The canceled races from Wednesday will be offered Sunday and Monday, though racing secretary Martin Panza expressed frustration Thursday at the absence of horses from Wednesday’s program who had been entered for Sunday. In the first four days of the Oak Tree at Hollywood Park meeting, from Sept. 30 through Oct. 3, field sizes averaged 7.44 horses. Last year, during the first five days of racing of the Oak Tree at Santa Anita meeting, field sizes averaged 8.3 runners per race. Zenyatta jogs on main track Zenyatta, who stretched her unbeaten streak to 19 races in the Grade 1 Lady’s Secret Stakes last Saturday, jogged 1 1/8 miles on the main track at Hollywood Park on Thursday, her first day back to the track. Trainer John Shirreffs had planned to send Zenyatta to the track Wednesday, but a morning rainstorm put an end to those plans. “It started raining at the wrong time for her,” Shirreffs said. Shirreffs said Zenyatta is likely to have three workouts at Hollywood Park in October in the build-up to the $5 million Breeders’ Cup Classic at Churchill Downs, the final start of her career. Shirreffs has tentatively scheduled Zenyatta’s first workout in that series on Oct. 14. She will remain at Hollywood Park until Oct. 31 or Nov. 2. Proctor plans California string Trainer Tom Proctor will have a 20-horse stable in California this winter, a group that will feature horses owned by long-time client Leonard Lavin’s Glen Hill Farm. Proctor said his stable will feature horses owned by other clients and may include Keertana, a winner of 7 of 20 starts and $542,771 who won the Grade 3 Glens Falls Handicap at Saratoga during the summer. Keertana was fourth in the Grade 1 Flower Bowl Invitational at Belmont Park last Saturday and is a candidate for the Breeders’ Cup Filly and Mare Turf at Churchill Downs on Nov. 5. Proctor said his stable will have divisions in Florida and California this year. This winter will be the first time he has had a stable in California since 2001. “I’ve got the 10-year itch,” he said. “Every 10 years I come out here.”
