Calder Race Course in Miami will cut overnight purses by 12 percent beginning Aug. 30 because of a drop in business due to head-to-head competition with nearby Gulfstream Park and a loss of revenue from simulcast fees, the track announced Sunday.

Take your pick in a $12,500 claiming race for 3-year-olds and up that will serve as the feature race at Northlands Park on Wednesday. The one-mile race goes as the seventh race, and it is hard to take a firm stand on any of the nine horses entered. Post time for the first of eight races is 6 p.m. Mountain.

ETOBICOKE, Ontario – The fields for the Halton and Elgin, two of the four $125,000 yearling sales stakes for 3-year-olds and up here Wednesday evening, will not be finalized until the scratches are in. Pender Harbour, Good Better Best, Aldous Snow, and Renegade Man all have been cross-entered in the two stakes, with the Halton at one mile on turf and the Elgin a 1 1/16-mile Polytrack race.

And with the races having been drawn last Friday, their connections will have had plenty of time to ponder their preferences.

ETOBICOKE, Ontario – Six stakes for graduates of local yearling sales are on tap Wednesday at Woodbine as a prelude to the Canadian premier yearling sale at the Woodbine Sales Pavilion on Sept. 3 and Sept. 7. Billed as Canadian Millions Sales Stakes Day, the races will be broadcast on Sportsnet ONE from 7-10 p.m. Eastern.

The two 6 1/2-furlong stakes for 2-year-olds are worth $200,000 apiece. Go Greeley should be favored in the Simcoe for colts and geldings, and On Rainbow Bridge is the one to knock off in the Muskoka for fillies.

A Thousand Aces ($17.80), a 3-year-old gelding claimed for $4,000 at Sacramento, outdueled Tiger Cat in the lane to win the $30,550 C.J. Hindley Humboldt County Marathon on Sunday at Ferndale.

A Thousand Ace’s victory denied trainer Quinn Howey an almost-perfect Humboldt County Fair meeting. Howey set a record with 16 wins, but the win he wanted most in the Marathon eluded him. He saddled three runners, Tiger Cat, odds-on favorite Graeme Crackerjack, and Surfer Dave, who finished second, third, and fourth.

Chu and You scored a front-running, 2 1/2-length victory in the $49,500 Barbara Shinpoch Stakes at Emerald Downs on Sunday night to remain unbeaten in three career starts and get her second stakes win.

DEL MAR, Calif. – The track was considered his Kryptonite, he needed a last-second replacement rider for a replacement rider, and 11 others were signed up to get him, some seemingly with the speed to make it a challenge. But there was one thing Game On Dude had that the others in the Pacific Classic did not: He was the best horse – by far.

DEL MAR, Calif. – Late-August stakes at Del Mar are ideal for Fed Biz.

In 2012, Fed Biz won the $100,000 El Cajon Stakes for 3-year-olds over a mile Aug. 31. On Sunday, he won a more valuable prize, the $251,750 Pat O’Brien Stakes over seven furlongs.

Fed Biz set a track record of 1:21.12, slightly faster than the 1:21.17 mark set by Lewis Michael in the same race in 2008. The victory gave Fed Biz a fees-paid berth to the Breeders’ Cup Dirt Mile at Santa Anita in November. Last November, Fed Biz finished eighth of nine in the BC Dirt Mile at Santa Anita.

DEL MAR, Calif. – For a horse accustomed to being on the lead, Obviously started slowly in the Del Mar Mile Handicap on Sunday, but he soon got in gear and saved his best for last.

OCEANPORT, N.J. – Summer Applause, trounced by multiple Eclipse Award winner Royal Delta in the Grade 1 Delaware Handicap in her previous start, scored a confidence-restoring victory in the $72,750 Lady’s Secret Stakes for fillies and mares Sunday at Monmouth Park.

After a slight bobble at the break, Summer Applause assumed a stalking position before rallying three wide on the final turn.
