Saturday’s $100,000 Marshua’s River Stakes at Gulfstream Park will have a large field headed by an established turf star and several promising younger challengers.

The Grade 3 race is 1 1/16 miles on turf for fillies and mares 4 years old and up and could have a maximum-permitted field of 14.

The Marshua’s River has 15 entrants, including the also-eligible Wallis, who could run if one or more of the other horses are scratched. Daveron, a 7-year-old trained by Graham Motion, is the 3-1 morning-line favorite based on her record in major stakes last year. Louvakhova, Tapitsfly and Trip for A.J. are among the top challengers.

Daveron had three wins in four starts in 2011, all in turf stakes. Her victories included the Ballston Spa (Grade 2) at Saratoga Race Course and the Beaugay Handicap (Grade 3) at Belmont Park.

Rajiv Maragh will ride Daveron. Eddie Castro, her jockey in all of last year’s races, has been sidelined since October with a hairline fracture in his vertebra.

Because the Marshua’s River has conditions based on 2011 graded-stakes wins, Daveron will carry 123 pounds, and the other horses will carry 117 pounds.

Louvakhova, a 4-year-old trained by Marty Wolfson, will make her second U.S. start. She raced in France until her owner, Michel Jean Zerolo, sent her to Wolfson early last fall.

On Oct. 15, Louvakhova won the Frances A. Genter Stakes by 4 1/4 lengths at Calder Casino & Race Course. She was pulling away at the end of that one-mile turf stakes. Since then, Wolfson scratched her from a race at Churchill Downs because he did not like the outside post position and twice could not get her into Gulfstream races in which she drew also-eligible posts.

Louvakhova has post nine Saturday and will be ridden by Luis Saez, who was on board in the Calder race.

• Gulfstream’s feature race Sunday is the $60,000 Ocala Stakes, at one mile on dirt for Florida-bred fillies that are 4 years old and up. Beginning next week, Gulfstream will add racing on Wednesdays and will have a Wednesday-through-Sunday schedule for most of its season that runs through April 8.
