As Penn National gets set for the first $1 million night in its 40-year history, there are varying levels of interest in the six stakes, including the $500,000 Penn Mile for 3-year-olds on the grass.

Entries for Saturday’s card will be taken Wednesday, but more than 50 horses were nominated to the Penn Mile, including the winners of seven of the eight graded stakes on grass for 2-year-olds in 2012 and 3-year-olds in 2013.

Horseplayers who fancy grass races and the pick six will be delighted with Thursday’s sequence, as five of the last six races at Belmont Park are scheduled for turf, including two allowance races that share top billing.

Trainers Christophe Clement and Bill Mott will saddle contenders in both races.

In race 7, a second-level allowance at one mile with a $62,500 optional-claiming price, Clement sends out Border Song, a French import formerly trained by his brother Nicolas, who came out on the shortest end of a three-way win photo in his U.S. debut April 20 at Keeneland.

INGLEWOOD, Calif. – A training-track accident at Betfair Hollywood Park has delayed the comeback of 2011 champion sprinter Amazombie, who will miss the summer season and possibly his entire 7-year-old campaign.

Amazombie has not started since Nov. 3, 2012, finishing eighth as the favorite in the Breeders’ Cup Sprint at Santa Anita, a race which he won in 2011. This winter, Amazombie was plagued by quarter cracks.

Owner-trainer Bill Spawr was targeting the Grade 1 Bing Crosby in summer at Del Mar until the mishap early this month.

INGLEWOOD, Calif. – Hall of Fame jockey Gary Stevens revised his career total of classic wins to nine with an upset victory on Oxbow in the Preakness Stakes at Pimlico on May 18. On Monday, Stevens, 50, won his first Grade 1 at Betfair Hollywood Park since 2004, as Marketing Mix prevailed by a head in a thrilling edition of the $250,500 Gamely Stakes for fillies and mares on turf.

GRAND PRAIRIE, Texas – Master Rick keeps getting better. He won his third straight race Monday in the Grade 3, $300,000 Lone Star Park Handicap when he stepped outside his comfort zone and conquered 1 1/16 miles. The race was the richest of the meet at Lone Star Park.

The improving Summer Hit ($4.60) rated nicely on an uncontested lead and scored his first graded stakes victory Monday at Golden Gate Fields with an impressive score in the $100,000, Grade 2 All American Stakes.

The Bertrando gelding, who began his career by winning a $12,500 maiden claimer, had run second in the Grade 3 San Francisco Mile on the turf in his last start. He won the Silky Sullivan Stakes on the turf here last year.

SHAKOPEE, Minn. – Jockey Giovanni Franco learned he was picking up the mount on Bet Seattle in Monday’s $50,000 Honor the Hero Stakes at Canterbury Park at 9 a.m. the day of the race. After a bold inside move at the top of the lane through a hole left open by a tiring Stig’s Deputy, he found himself standing in the winner’s circle.

“My agent called me this morning and told me I had the ride, so I got instructions and rode the race,” Franco said.

Paco Lopez scored a stakes double on Monday as Monmouth Park closed out the Memorial Day weekend on the Jersey Shore.

Lopez was aboard Silverette, a confident winner of the $61,800 Red Cross for filly and mare sprinters. He followed up with a 10-1 upset on Rusty Slipper in the $63,600 Little Silver for 3-year-old fillies on the turf. It was the first stakes win for both fillies.

Silverette, a gray 4-year-old trained by Dale Romans, was well in hand in the deep stretch.

“She had plenty left to hold everyone off,” Lopez said.

LOUISVILLE, Ky. – After Beat the Blues broke sharpest of all in a field of five filly-mare sprinters Monday in the Grade 3 Winning Colors Stakes at Churchill Downs, jockey Miguel Mena held his position as long as he could – which was all the way to the wire.

In the last of six furlongs, Beat the Blues held off a steady surge from odds-on favorite Judy the Beauty to take the 10th running of the $108,000 Winning Colors by three-quarters of a length.

ELMONT, N.Y. - Rebounding from a fifth-place finish in the Kentucky Oaks, Midnight Lucky turned in a dominating performance to win Monday’s 83rd running of the Grade 1 Acorn Stakes by better than six lengths over Close Hatches, who was exiting the Kentucky Oaks as well.
