Trainer happily takes abuse from good filly


GRAND PRAIRIE, Texas - Randy Mayfield feels the pain when the top two horses in his stable are ready to run. Gold Nugget broke the trainer's toe before winning last year's Dallas Turf Cup, and over the weekend, Coastalota, who drops from stakes to optional claiming company Thursday night at Lone Star Park, cow-kicked the trainer, bruising his thigh.

"She kicked me and it sounded like a gun went off," said Mayfield, who was injured when grazing Coastalota last Sunday. "It made a big echo. She liked to break my leg."

Mayfield holds no grudge against Coastalota. Instead he is excited about her future, and would like to see the filly, a stakes winner on dirt, develop into a female version of Gold Nugget, who since being transferred to turf has earned $483,649.

Coastalota makes her second career start on turf Thursday after running second, beaten seven lengths by Nanie's Dinner, in the $100,000 Allen Bogan Memorial on dirt at Lone Star. In her turf debut, she finished fourth, beaten a length, against allowance foes June 17.

Mayfield said a strategy to take Coastalota well off the pace in her turf debut worked against her, and he looks for her to move forward in her second start on the surface. "She shows up every time I lead her over, but in my opinion, I think she's going to be a better grass filly," said Mayfield. "Her mama was a multiple stakes winner on the grass; she was strictly a grass horse."

Mayfield said Thursday's race will serve as the filly's springboard to the $50,000 Margarita Breeders' Cup, to be run over 1 1/16 miles on turf at Retama Park on Aug. 4.

Coastalota is entered at the same distance Thursday, and faces a deep field. Her chief rivals include Slapstick, who in her last start won a conditioned allowance race for leading trainer Steve Asmussen. Casey Lambert has the mount on Coastalota. Corey Lanerie, who returns from a week's suspension Thursday, has the mount on Slapstick.

Premeditation a supplement

Premeditation, an impressive four-length maiden winner last month at Lone Star, will be a $5,000 supplement to the $100,000-estimated Middleground Stakes on Saturday, said trainer Bill Leach. The race is one of three closing-weekend stakes at Lone Star.

The Middleground, a 5 1/2-furlong race for 2-year-olds, is also expected to draw Nuclear Assembly, who set a track record for five furlongs when he won a division of the $150,000 Texas Thoroughbred Association Sales Futurity in 57.41 seconds. He is undefeated in three starts for trainer Brent Davidson.

Leach said a decision to supplement Premeditation came after the colt worked five furlongs in a bullet 58.80 seconds last Friday under jockey Curt Bourque.

Premeditation has the pedigree to develop into a promising runner for his owner, Bill Clifton of Waco, Texas, who also owned Behrens, a winner of more than $4.5 million. Premeditation, a $190,000 yearling purchase, is by Afternoon Deelites, a Grade 1 winner at 2, and is out of a full sister to multiple Grade 1 winner Diazo. Leach said that to go along with his pedigree, Premeditation has the right attitude for racing. "He's aggressive on the track, and in his stall he's very easy to fool with," Leach said. "He has a good temperament."

Beyond the Middleground, the colt is eligible for the $100,000 El Joven at Retama Park on Sept. 1.
