Seven 2-year-olds, all with limited or no experience racing on grass, will race 7 1/2 furlongs on turf in the $50,000 Nick Shuk Memorial Stakes at Delaware Park.

Special Skills, a winner over nine rivals in a six-furlong turf sprint at Belmont Park in his career debut, and Private Tutor, second over yielding ground in his turf debut in the Chenery at Colonial Downs, are the only horses in the Shuk field who have raced on grass.

Based on pedigree, first-time starter Seventeenohsix and second-time starter Incognito Bandito should take to the turf.

Allen Did It, disqualified from an apparent victory for running erratically in the stretch, and Paco Smart, a two-time stakes winner last season but 0 for 2 this year, will look to rebound in Saturday’s $50,000 Robert Leavitt Stakes for West Virginia-bred 3-year-olds at Charles Town.

Dale Romans’s strong arsenal of stakes stars will be represented here Sunday by Shackleford, who has been supplemented into the Grade 1 Alfred Vanderbilt Handicap. The six-furlong stakes drew a field of eight that also includes Emcee, Justin Phillip, Rothko, Poseidon’s Warrior, Sloane Ranger, Jersey Town, and Hamazing Destiny.

ARLINGTON HEIGHTS, Ill. – If a bettor had come to the Arlington Park meeting in 2010 and decided to bet every Jim DiVito-trained 2-year-old over the next three seasons, that bettor would be rolling in dough. DiVito’s record with juveniles the last three Arlington meetings is nothing less than remarkable: From 43 starters he has compiled a record of 21-7-4, good for a return on investment of $4.33. In addition the 48 percent strike rate, consider that almost twice as many DiVito 2-year-olds have won than failed to finish third or better.

AUBURN, Wash. – Sis’s Sis, a two-time stakes winner, headlines the feature race Saturday at Emerald Downs. A $32,000 claimer for fillies and mares at 6 1/2 furlongs, the race attracted five entrants, and each of the five has a realistic chance to win it. First post for the nine-race card is 2 p.m. Pacific.

SARATOGA SPRINGS, N.Y. – Even if he wasn’t running the dual Grade 1 winner Ron the Greek in Saturday’s $750,000 Whitney Handicap Invitational, trainer Bill Mott would still feel good about his chances of winning the prestigious Grade 1 race at Saratoga.

That’s because Mott also will saddle Flat Out, last year’s Grade 1 Jockey Club Gold Cup winner, in the Whitney, and though he’ll likely be a longer price than Ron the Greek, his chances to succeed are equally as good, if not better, than his stablemate.

The undefeated Wups has been favored in all three career starts but is unlikely to be favored when he enters the gate for Saturday’s Robert Dupret Derby at the Sonoma County Fair in Santa Rosa.

Winners of the $5,000 Boise Open Derby don’t get much respect when they venture out of Idaho, particularly when they are about to make their turf debut.

Trainer Paul Treasure is confident going into the race – not that Wups will beat his six rivals in the 1 1/16-mile stakes for 3-year-olds but that he will prove very competitive.

ALTOONA, Iowa – With over $540,000 on the line, Iowa Classic Night, with its seven stakes races intended to clarify the championship picture for this season’s Iowa-breds, is the long-awaited meet highlight for local horsemen.

The card starts off with a bang as a deep group of juvenile fillies contest the $75,000 Iowa Sorority. In a year when the fillies have outshined the colts, the Sorority, contested over six furlongs, features a talented group of eight.

DEL MAR, Calif. – For a multiple stakes-winning millionaire, Switch has a recent void in her career. She has not won a graded stakes at a mile or farther since the Grade 2 Hollywood Oaks in June 2010.

It certainly has not been for a lack of trying. She was second in three consecutive Grade 1 route races in California and Arkansas in the spring of 2011, and second to Zenyatta in the 2010 Lady’s Secret Stakes at Hollywood Park.

SARATOGA SPRINGS, N.Y. –Trainer Dale Romans said that Dullahan, fifth in last Sunday’s Haskell, could make his next start on the Polytrack at Del Mar against older horses in the Grade 1 Pacific Classic on Aug. 26.

“He came out of the race fine and he’s back at Churchill Downs right now,” said Romans. “We’re going to talk about it this week and see what our options are. The Pacific Classic is one of those options. I’d like to try him on the Poly again. Turf’s an option as well but really the big turf race is the Secretariat and Jerry has Finnegan’s Wake for that spot.”
