The Breeders' Cup Classic is Saturday at Lexington's Keeneland Race Course, with a 10-horse field battling it out for the season-ending, $6 million purse.

Driving the news: All eyes will be on legendary trainer Bob Baffert, whose decades of unprecedented success have been peppered with numerous doping violations, including four in the last six months alone.

Details: The Breeders' Cup World Championships are a two-day, 14-race event with $31 million in prizes. The main event is the last of those 14 races.

  • Post time: 5:18pm ET (NBC)
  • Field: Improbable (5-2) is the betting favorite. Full field.

The big picture: Baffert is by far the most decorated trainer in the sport's history. His horses have won six Kentucky Derbies, seven Preakness Stakes, three Belmont Stakes and three Kentucky Oaks. He's also trained the past two Triple Crown winners — American Pharoah (2015) and Justify (2018).

  • He's avoided serious penalties for doping violations — a small fine here, a brief suspension there — but one's reputation can only withstand so many nicks.
  • On Wednesday, he pledged to run "a tighter ship" moving forward. "Horses have been my life and I owe everything to them and the tremendous sport in which I have been so fortunate to be involved," he said.

The bottom line: Three of the 10 horses in tomorrow's race were trained by Baffert — odds look pretty good to claim another big win.

Americans increasingly see China as an enemy

One in three Americans, and a majority of Republicans, now view China as an enemy of the United States, according to a new survey from Pew Research Center.

By the numbers: Just 9% of Americans consider China a "partner," while 55% see Beijing as a "competitor" and 34% as an "enemy."

Scoop: Leaked HHS docs spotlight Biden's child migrant dilemma

Fresh internal documents from the Department of Health and Human Services show how quickly the number of child migrants crossing the border is overwhelming the administration's stretched resources.

Driving the news: In the week ending March 1, the Border Patrol referred to HHS custody an average of 321 children per day, according to documents obtained by Axios. That's up from a weekly average of 203 in late January and early February — and just 47 per day during the first week of January.

Mounting emissions data paints bleak picture on Paris climate goals

Illustration: Aïda Amer/Axios

Researchers keep finding new ways to reveal that nations are together showing very few signs of getting on track to meet the Paris Agreement's goals.

One big question: That's whether a spate of recent analyses to that effect, and scientific reports coming later this year, will move the needle on meaningful new policies (not just targets).
