The Grade 2 $1.25 million Pennsylvania Derby features the two biggest names from the Triple Crown trail September 24 at Parx as a field of 12 gathers in one of the most intriguing betting races of the year.

The $1 million Cotillion Stakes September 24 at Parx features a true clash of the titans as the six-horse field is headlined by the undefeated, five-time grade 1 winner Songbird who figures to face the most stern challenge of her career.

In a completely wide open renewal of the Presque Isle Mile September 18 at Presque Isle Downs, 13 runners including the also-eligible will contest the eight furlong trip over synthetic footing.

Champion Songbird is set to make her much-anticipated return to the races in the $200,000 Summertime Oaks at Santa Anita on Saturday. The Grade 2 event will be run at a mile and a sixteenth and has attracted a field of seven.
