What could prove to be an especially fruitful summer at Saratoga for the three-year-old filly Nitrogen continues on Saturday when the rising star looks to capture her sixth stakes win in a row in the $500,000 Belmont Oaks (G1) over nine furlongs on the turf.

The Saturday card at Keeneland includes a trio of rich turf stakes: the $1.25 million Turf Mile (G1), the $750,000 First Lady (G1), and the $350,000 Woodford (G2).

Royal Ascot wrapped up on Saturday with a mix of blowout victories and dramatic head-to-head battles. Three group stakes, including an exciting renewal of the Queen Elizabeth II Jubilee (G1), led the action.

For the sixth time since 2011, trainer Aidan O’Brien and jockey Ryan Moore teamed up to win the $1 million Breeders’ Cup Juvenile Turf (G1), taking Friday’s renewal at Santa Anita with Unquestionable.

International participation during Breeders’ Cup Friday has come up strong. Horses representing England, Ireland, France, and Japan are among the entries.
