WINNIPEG, Manitoba - Speedy Treat is the one to beat in Saturday's $35,000 Manitoba Maturity at Assiniboia, for 4-year-olds bred in Manitoba going 1 1/16 miles.

Never worse than third in five lifetime outings, Speedy Treat made his first four starts this year for trainer Harry Kube but will be racing for trainer Emile Corbel for the first time Saturday.

Speedy Treat's lone win came in his seasonal bow May 12, and he since has raced competitively in three tries against allowance company, including a second-place finish in his latest here June 30.

MIAMI - Never in Calder Race Course's 30-year history have so many outstanding horses competed on the same day as on Saturday in the third annual Summit of Speed, six sprint stakes worth $1.4 million.

Entries were drawn Wednesday for the Summit of Speed, which has lured 18 shippers to south Florida, led by Eclipse Award winner Xtra Heat. She will take on Gold Mover and four others in the $400,000 Princess Rooney Handicap, which will share top billing on the card with the $400,000 Smile Sprint Handicap.

ELMONT, N.Y. - Trainer Todd Pletcher is not necessarily looking to make a turf horse out of Smok'n Frolic. He is just looking for a spot in which to bring her back off an extended layoff.

ARLINGTON HEIGHTS, Ill. - An Illinois-bred gets a maiden race and two allowance conditions, then it's out of statebred company and into the big, scary world of open racing. It's a tough jump for a horse to make, and he needs a little luck to do it.

But how much luck does has trainer Christine Janks have left?

She used much of it Sunday, when she won three times in the first five races.

INGLEWOOD, Calif. - The depth of Bobby Frankel's stable is on display in Friday's sixth race at Hollywood Park.

Frankel has two leading contenders in a field of 10 in a $50,000 allowance over 1 1/16 miles on turf - Fully Invested and Northern Blue. Both are 4-year-old fillies with stakes experience in Europe who are making their first start in this country.

Fully Invested had one win in five starts in England, including a third in a listed stakes over about 1 1/4 miles in May 2001. She is unraced since October, when she was sixth in a stakes at Newmarket.

ETOBICOKE, Ontario - Stronach Stable and trainer Malcolm Pierce have won numerous turf races at Woodbine since they teamed up a few years ago, most recently with Montezuma's Gold last weekend.

That same combination will send out Silver Axe in Friday's feature, a 1 1/8-mile grass event for $80,000 optional claimers.

AUBURN, Wash. - Victor Slew may have a slight edge over an otherwise evenly matched group of 10 in Friday's best race at Emerald Downs, a 6 1/2-furlong sprint for 3-year-olds eligible to be claimed for $25,000.

VANCOUVER, British Columbia - Thundering Herd will likely be favored over seven other 3-year-olds going 1 1/16 miles and running for a top claiming price of $25,000 in the Hastings Park feature race this Friday evening. First post is 5 pm.

EDMONTON, Alberta - The second local stakes prep for the Aug. 24 Canadian Derby goes Saturday, and Dark Fuse will be one of the favorites after having won the $40,000 Western Canada impressively here June 29.

Dark Fuse, a 3-year-old Washington-bred, might never have raced at Northlands Park, except a scar on his leg front leg scared off potential buyers at a yearling sale in Washington.

"He's a very nice horse with good breeding, and if it wasn't for the scar on his knee he wouldn't even be here," said Ron Burrell, who trains Dark Fuse.

Jockey Yamil Rosario was in stable condition with a head injury Wednesday after being thrown from his mount and trampled during a race at Colonial Downs on Tuesday evening, The Associated Press reported.

Rosario was on Pyrite Missy in the fifth race when the horse clipped heels with another runner on the first turn and went down, throwing Rosario forward. Rosario was trampled by Pyrite Missy and possibly others. The semi-conscious rider was taken to Medical College of Virginia Hospitals in Richmond.
