MIAMI - Calder's Summit of Speed has become one of the premier racing days on the national calendar. The question this year is whether the ongoing conflict between local horsemen and track owner Churchill Downs Inc., and the purse cuts that have resulted from that stalemate, will put a damper on this year's edition of the event, to be decided July 12.

Wrenice has long been one of the Southwest's best dirt sprinters, but Saturday in an allowance sprint at Lone Star Park she opened up a new world of options when she won on turf for the first time. Now, trainer Randy Mayfield is plotting a campaign to get her to the $200,000 Turf Amazon Handicap for fillies and mares at five furlongs on turf at Philadelphia Park on Sept. 27.

"How we do it, we don't know yet," said Mayfield, who trains Wrenice, a seven-time stakes winner of more than $400,000, for Stewart Hamblen. "We're working on it."

INGLEWOOD, Calif. - Jerry Hollendorfer's stopwatch failed him when his star older horse Heatseeker worked at Hollywood Park on Sunday morning. Considering what Hollendorfer saw, it was not a major concern.

Hollendorfer timed Heatseeker's workout in 59.47 seconds. The official time was 57.80 seconds, the fastest of 59 works at the distance. The times may have differed, but one thing is certain: Heatseeker is ripe for his third major stakes win of 2008 in Saturday's $750,000 Hollywood Gold Cup.

ELMONT, N.Y. - After watching two favorites in out-of-town stakes disappoint, trainer Christophe Clement had his spirits get a boost Saturday as Mauralakana outfinished a stubborn Dynaforce to win the Grade 2, $250,000 New York Stakes by a neck at Belmont Park.

Dynaforce, making her seasonal and North American debut and first for trainer Bill Mott, held second by a neck over the late-running Hostess. Tejida, the pacesetter, finished fourth followed by Archstone.

Patrick Valenzuela crept closer to the 4,000-win level when he booted home five winners on Sunday's card at SunRay Park in Farmington, N.M. He also had two seconds and a fourth from his eight mounts.

"Not a bad day at all," Valenzuela said Sunday evening as he was leaving for Durango, Colo., to visit one of his daughters. "Five wins, two seconds, and a fourth, wow!"

Valenzuela was under the radar on Saturday, finishing third with his lone mount in his first trip to SunRay Park. But he was a crowd favorite on Sunday when he went 3 for 3 early.

Sent straight to the lead by jockey Jeremy Rose, Sweet Hope stayed in front throughout Monday's $60,650 Beautiful Day Stakes at Delaware Park, winning by three lengths. Puskita, who had chased the front-runner the whole way, was a clear second, 5 1/4 lengths ahead of third-place My Heavenly Sign.

Sweet Hope, a 3-year-old Kentucky-bred daughter of Lemon Drop Kid, was making her first start for trainer Larry Jones and her third start in the United States after beginning her racing career with 1 victory in 6 starts in England.

The Golden Gate Fields meeting ended Sunday, and for the first time since 1986, Jerry Hollendorfer did not win the training title at a major Northern California track.

Billy Morey, who saddled four winners Saturday, ended Hollendorfer's reign. He won 25 races to 23 for Hollendorfer, who tied with Steve Miyadi for second in the standings. Hollendorfer had won 32 straight Golden Gate Fields training titles.

The 34-year-old Morey sent out 78 starters and won at a 32 percent clip at the meet, which began on May 14. Hollendorfer saddled 107 runners and Miyadi 80.

Jockey Michael Baze is expected to be sidelined for three weeks after sustaining a fractured bone in his neck in a spill on Friday night at Hollywood Park, according to his agent, Nick Cosato.

Baze was hurt when the horse, Charlotta, broke down on the turn of the second race, a six-furlong maiden claimer. Charlotta was euthanized because of her injuries, said track stewards.

Baze, 21, will wear a soft collar during his recovery, and could return in time for the start of the Del Mar meeting on July 16, Cosato said.

EDMONTON, Alberta - Inuit Fisher is good right now and getting better, as evidenced by his handy 3 3/4-length tally in last Saturday's Journal Handicap, his third victory in as many weeks for the red-hot trainer Dale Saunders.

Inuit Fisher, a bargain $4,500 yearling purchase owned by the president of Alberta's Horsemen's Benevolent and Protective Association, Jim McFadyen, paid $7.60 in the $50,000 handicap.

LOUISVILLE, Ky. - Curlin had his first workout since the Stephen Foster Handicap when he breezed an easy five furlongs early Monday over a fast main track at Churchill Downs.

With regular exercise rider Carmen Rosas aboard, and without company, Curlin proceeded through fractions of 13.26, 26.22, 38.80, and 51.33 seconds before hitting the wire in 1:03.81. His six-furlong gallop-out time was 1:17.02.

"I was very pleased with how he went to the track today," said trainer Steve Asmussen. "He looked beautiful. Nice and smooth."
