The seven-furlong sprint for three-year-olds is on the Travers undercard and has a field of eight. Uncle Mo has drawn post seven with John Velazquez set to ride.
Owned by Mike Repole, Uncle Mo has not started since finishing third in the Wood Memorial and was later diagnosed with cholangiohepatitis, a liver disorder.
"Uncle Mo right now is training 110 percent," Repole said Wednesday. "To be on the undercard of the Travers, that's pretty special."
Winner of last year's Breeders' Cup Juvenile, the Eclipse Award honoree has won four of five career starts for $1,436,000. In his only start this year prior to the Wood, Uncle Mo easily won the Timely Writers Stakes at Gulfstream Park.
"For Uncle Mo to right now just have only the Timely Writer on his resume as the only victory he has this year, that's not going to get him top 3-year- old," said Repole. "If he wins the King's Bishop, and then we go either Jockey Club Gold Cup or Pennsylvania Derby, and there's a lot of ifs, and then we go Breeders' Cup Mile or Classic, and he just happens to be lucky and sweep that, then that's a pretty impressive resume."
Trainer Donnie Von Hemel has Caleb's Posse entered in the King's Bishop off a victory in Saratoga's Amsterdam Stakes. The colt will be ridden by Rajiv Maragh from post two.
"It certainly should have pace in the race," Von Hemel said. "It?s a tough spot, but the horse ran so good that last race. There aren't many seven- furlong races for three-year-olds in the country."
Caleb's Posse won the Ohio Derby on June 4, but finished fourth three weeks later in the Iowa Derby. Owned by McNeill Stables, the colt has won six of 13 career starts for $408,304.
One time Kentucky Derby contender Flashpoint will break from the rail with Cornelio Velasquez in the saddle. The colt is trained by Wesley Ward for Peachtree Stable.
Flashpoint won the Hutcheson Stakes in February at Gulfstream Park, but was fourth in the Florida Derby and 14th in the Preakness. He came back to win the Jersey Shore Stakes in the mud at Monmouth Park last month. In five starts, all this year, he has three wins for $255,200.
Here is the complete field for the King's Bishop from the rail out: Flashpoint, Cornelio Velasquez; Caleb's Posse, Rajiv Maragh; Runflatout, Robby Albarado; Dominus, Julien Leparoux; Poseidon's Warrior, Frank Pennington; Justin Phillip, Ramon Dominguez; Uncle Mo, John Velazquez and Cool Blue Red Hot, Manny Cruz.
The King's Bishop will be broadcast by NBC Sports with a post-time of 5:12 p.m. (et).
