While the $1 million Pennsylvania Derby (G1) and Cotillion (G1) are the richest prizes at Parx Saturday, notable names will appear on the stakes-laden undercard as well.

Bob Baffert has won two of four runnings of the Pegasus, and the Hall of Fame trainer should have a strong hand in the fifth edition.

A much improved effort in the Monmouth Cup (G2) makes Math Wizard the potential horse to fear in the $600,000 Charles Town Classic (G1) over 1 1/8 miles.
