Eight 3-year-olds, led by Preakness winner Deputed Testamony, are entered in Saturday's 19th running of the 1 1/8-mile Governor's Handicap at Bowie, the richest race in the track's 38-day summer meeting.
Deputed Testamony is part of an entry with Parfaitement, who also has been entered in the Jersey Derby at Atlantic City.
Bowie racing secretary Larry Abbundi has assigned Deputed Testamony high weight of 124 pounds.
Herb McCauley, who rode Parfaitement in the Triple Crown races, will ride the Preakness winner, while Parfaitement will be ridden by Paul Nicol, who guided him to a nose victory in the Marylander Stakes earlier in the meeting.
Chief competition for the Bill Boniface-trained entry is expected to come from Country Pine, Dan Galbreath's Withers winner.
Country Pine has beaten several top colts, including Megaturn, one of Saturday's contenders.
Country Pine has been working briskly for trainer Lou Rondinello and is the second high weight at 119 pounds. The son of His Majesty will be ridden by Jerry Bailey.
Megaturn, who finished in front of Deputed Testamony in the Belmont Stakes, is at 117 pounds, along with Bet Big.
Megaturn will be ridden by Reuben Hernandez; Bet Big will have Donald Miller as his rider.
Completing the field for the $100,000-added event are Hardi, Bold Relic and Princillian.
Second billing to the Governor's Handicap will go to the $25,000-added Toddler Stakes for 2-year-old fillies.
The favorite's role for the 5 1/2-furlong race is expected to be shared by Alden's Ambition, Make an Entrance and Me Darlin Ann B.
Laurel President John D. Schapiro has assured horsemen that the turf course will be protected during this weekend's rock concerts at the track.
Turf racing was discontinued for several days last summer when trucks with heavy equipment gouged deep ruts in the new turf course that had been softened by rain.
