Mareina: Fresh horses, high win percentage


GRAND PRAIRIE, Texas - Keep an eye on Mike Mareina the rest of the meet at Lone Star Park. The trainer, who is winning races at a more than 25-percent clip in his first meet here, said his 28-horse stable has something left in the tank for the second half of the meet, which runs through July 14.

"I want to try and win about 10 races this next month," said Mareina, whose barn has already racked up nine wins at Lone Star to rank sixth in the standings behind leader Cole Norman.

Mareina said he has five or six new horses to run, while his other horses, who he has taken care not to over-campaign this meet, are coming into their races fresh.

Mareina tried Lone Star for the first time this year at the request of some of his owners, and during the course of the meet has developed two quality 4-year-old colts. One is Race on Green, a 4 1/2-length allowance winner last Saturday. Race on Green is scheduled to make his stakes debut at Lone Star next month in the $75,000 Bob Johnson Memorial.

"He keeps getting a little better every race," said Mareina, who trains Race on Green, a son of A.P. Indy, and two-time Grade 3 winner Grab the Green for Kuehne Racing.

Kuehne Racing also owns the promising Halo Cat, who has won both of his Lone Star starts. In his most recent race, Halo Cat shipped to Manor Downs near Austin and romped by 10 lengths in the $30,000 Sprint Classic on May 26.

"He's coming into his own," said Mareina, who is debating what to do next with Halo Cat. Options include the Grade 3, $100,000 Aristides Handicap at Churchill Downs on June 29, the trainer said, and the $50,000 Kings Court at Louisiana Downs on June 28.

After the Lone Star meet, Mareina plans to ship back to Kentucky, where he spends most of his year, and race at Ellis Park, Arlington, and Churchill Downs. He winters at Fair Grounds in New Orleans.

Before going out on his own, Mareina, who is 50, worked as an assistant to Eclipse Award-winning trainer Bobby Frankel. Next year, he plans to return to Lone Star.

Seainsky auditions for Iowa Derby

Seainsky, a promising 3-year-old colt who finished second in his last start to Race on Green after a sluggish break, is the one to beat in the eighth race Wednesday night, a one-mile conditioned allowance for 3-year-olds and up that drew 12.

Seainsky removes blinkers for the race, and with a good performance will be pointed for either the $250,000 Iowa Derby at Prairie Meadows on July 5 or the Grade 2, $175,000 Arlington Classic on turf June 29.

"This horse is unbelievable," said Wes Hawley, who trains Seainsky. "He does things with such ease. I'd rank him up with any of the top 3-year-olds I've ever been around. Now, it's just getting him to do it."

Among the top 3-year-olds Hawley has worked with are Grade 2 winners Shot Gun Scott, Boundlessly, and Rockamundo. He looks for a good race from Seainsky on Wednesday, and has given the return call to jockey Gerard Melancon.

* Both divisions of the $150,000-estimated Texas Thoroughbred Association Sales Futurity will be run Saturday.
