OZONE PARK, N.Y. – Seth Klarman and Bill Lawrence decided a few years ago to stop partnering on horses, with Klarman opting to expand his stable while Lawrence was looking to downsize his involvement in racing. The pair, which owned horses together for 15 years, went out on a high note last week when Bricks and Mortar won the Breeders’ Cup Turf at Santa Anita, completing a perfect 6-for-6 campaign that could very well earn him Horse of the Year honors. Lawrence and Klarman, the latter who races under the banner Klaravich Stable, will run one last horse together Saturday when Frontier Market starts in the $150,000 Artie Schiller Stakes at Aqueduct. Frontier Market, a 6-year-old gelding by Lemon Drop Kid, is cataloged to be sold Wednesday at the Keeneland November bloodstock sale. “Three or four years ago we made a decision to go our different ways,” Lawrence said. “He was building up larger numbers, I wanted to go smaller. . . . I love the horses. It takes a lot of time. We’re trying to do something that my wife and other members of my family like to do more.” Frontier Market, trained by Chad Brown, has three wins and seven seconds from 11 career starts. He is coming off a head loss to Caribou Club in the Grade 3 Baltimore Washington International Turf Cup at Laurel Park on Sept. 21. Caribou Club is also entered in the Artie Schiller, but trainer Tom Proctor wants to run only if the turf is firm. A combination of rain and cold temperatures Thursday and Friday could make the turf less than firm. Frontier Market has handled all types of ground. Five of his runner-up finishes have come in races he lost by a head or a neck. “His numbers are fast and he seems to be a miler,” Brown said. “It’s taken a while for this horse to run on a regular basis, but the horse seems to be doing really well. His numbers fit.” His running style also fits the race shape, with plenty of speed supplied by Gidu, Dr. Edgar, Voodoo Song, and Abiding Star. The presence of speed should also help Caribou Club, who has won his last two from off the pace in races where there was ample speed. Caribou Club is the 125-pound highweight and would break from post 8 under Feargal Lynch. Curlin’s Honor, trained by Mark Casse, could potentially get the jump on Frontier Market and Caribou Club. Curlin’s Honor is coming off a confidence-building allowance win at Woodbine on Oct. 6 going 1 1/16 miles. He ran well in the Grade 2 King Edward going a mile at Woodbine, a race in which “he could have made the lead too soon,” trainer Mark Casse said. Joel Rosario will ride Curlin’s Honor from post 5. Just Howard won the Grade 3 Oceanport at Monmouth Park on the July 20 Haskell card. He finished fifth, beaten a length by Caribou Club in the BWI Turf Cup. Jose Ortiz replaces Trevor McCarthy. Thirteen were entered in the Artie Schiller, 10 for the turf and three for the main track. The Artie Schiller goes as race 8 on a 10-race card that begins at noon Eastern and includes the $100,000 Atlantic Beach for 2-year-olds on turf and the $100,000 Pumpkin Pie for female sprinters on dirt, a race rescheduled from the closing-day cancellation at Belmont Park.
