FLORENCE, Ky. – By finishing fourth as a 13-1 shot in his only start in a graded race, Thirtyfirststreet hasn’t justified any of his owners catching Kentucky Derby fever.

But that all could change Saturday at Turfway Park, where Thirtyfirststreet, a California-bred colt trained by Doug O’Neill, will be part of a wide-open field of Derby aspirants in the 40th running of the Grade 3, $500,000 Vinery Racing Spiral Stakes.

ARCADIA, Calif. – Santa Anita jockey Garrett Gomez, who led the nation in purse earnings four of the past five years, will hire a new agent in coming weeks while aiming to cut down on travel and spend more time with his family in California.

Gomez confirmed Wednesday that he and agent Ron Anderson will end their five-year business relationship after Santa Anita Derby weekend, April 9-10. Anderson will relocate to Kentucky; he has taken the book of jockey Alan Garcia effective with the start of the Keeneland meet on April 8.

Every great act deserves a decent warm-up. That’s the mindset of most racetracks in regard to their showcase events, and it’s why Fair Grounds has carded five $75,000 stakes on Friday, the day before the $1 million Louisiana Derby and other major races take center stage Saturday at the New Orleans track.

Star Guitar, easily the biggest favorite of the day – and surely the most popular Louisiana-bred of his era – helps lead off the action as the 1-5 morning-line choice in the first of the five stakes, the Costa Rising.

One Sweet Jess joined very elite company when he became the latest 400-yard track record holder at Los Alamitos last week.

Apollitical Jess later won the Champion of Champions and was named 2010 World Champion Quarter Horse.

Maclean's Music, a 3-year-old trained by Steve Asmussen for owner Jess Jackson, earned a 114 Beyer Speed Figure in his debut race Saturday at Santa Anita.

The Beyer is the highest for a debut race since the figures were first published in 1991.

The 2011 campaign for Caracortado will be purely North American and focus on the top grass races leading to the Breeders’ Cup Mile.

Trainer, breeder, and co-owner Mike Machowsky said Tuesday that the spring schedule for Caracortado will include the Grade 2 Arcadia Handicap at Santa Anita on April 9, Grade 1 Woodford Reserve at Churchill Downs on May 7, and Grade 1 Shoemaker Mile at Hollywood Park on July 2.

Machowsky had considered an international campaign for Caracortado, who was not originally nominated to the Breeders’ Cup.

OZONE PARK, N.Y. – The calendar says spring, but no one told Old Man Winter.

A forecast for mixed precipitation and temperatures in the low 40s may conspire to give Thursday’s inner track card a mid-winter feel – one that will only be reinforced by eight claiming races, three of which are for maidens.

Billy Morey amassed more than 1,000 wins in less than a decade during a remarkably swift rise among the ranks of North American trainers. Based in Northern California, Morey ventured out of town for one of his more notable victories a few weeks ago, and on Saturday, he will try for his greatest yet when sending out Positive Response in the $500,000 Vinery Racing Spiral Stakes at Turfway Park in Florence, Ky.

HOT SPRINGS, Ark. – Havre de Grace was more interested in peppermints than praise following her sparkling win in the Grade 3, $150,000 Azeri last Saturday at Oaklawn, but she is deserving of a heaping of both. She put up a Beyer Speed Figure of 105 while winning the race by three lengths over champion Blind Luck, and in the process established herself as the probable favorite for next month’s Grade 1, $500,000 Apple Blossom Handicap.

HALLANDALE BEACH, Fla. – The potent team of trainer Nick Canani, jockey Paco Lopez, and owner Frank Calabrese combined to win three races on Sunday’s program and figure to continue their winning ways when the improving Where’s Sterling starts as the favorite against seven rivals in Thursday’s $55,600 feature at Gulfstream Park. The main event will be run under first-level allowance conditions at 1 1/8 miles over the main track.
