Horse racing

Presious Passion scored a repeat victory in the $750,000 United Nations Stakes, smashing the course record at Monmouth Park in Oceanport, N.J.

The 6-year-old gelding ran the 13/8 miles on the firm turf in 2 minutes, 10.97 seconds, wiping out the mark of 2:12.89 set by English Channel in the 2007 U.N.

After leading by 20 lengths in the early stages, Presious Passion held off Lauro by two lengths, with Brass Hat third.

The U.N. was a Breeders' Cup "Win and You're In" stakes, ensuring a spot for Presious Passion in this year's Breeders' Cup Turf.

Hall of Fame rider Mike Smith is back on Mine That Bird, piloting the Kentucky Derby winner in the $750,000 West Virginia Derby and the $1 million Travers Stakes next month.

He takes over for Calvin Borel, who guided the 3-year-old gelding to a longshot win in the Derby and added a third-place finish in the Belmont Stakes.

Smith guided Mine That Bird to second place in the Preakness after Borel opted to ride filly Rachel Alexandra, which edged Mine That Bird for the win.

Trainer Bennie Woolley Jr. decided to drop Borel after the jockey said he couldn't make a firm commitment to ride Mine That Bird the rest of the year.
