No matter the outcome, Las Vegas odds makers like trainer Bob Baffert’s chances of picking up his fourth Kentucky Derby victory. With the first jewel in the Triple Crown only five days away, Baffert’s American Pharoah has surged ahead of Dortmund as the favorite to claim the 141st Run for the Roses Saturday at Churchill Downs.

According to the latest odds from, American Pharoah has shifted from 2/1 to 5/2, propelling past Dortmund, who was at 9/2 but moved down to 4/1.

Saddling two contenders in the Derby is nothing new for Baffert. Since 1996, he’s started at least two thoroughbreds in Louisville, according to the Lexington Herald-Leader. However, Baffert hasn’t secured a Derby victory since War Emblem’s run in 2002.

Based off their success during the prep season, it’s quite easy to understand why American Pharoah and Dortmund are the thoroughbreds to beat. Coming off a huge eight-length Arkansas Derby win, American Pharoah has captured four straight races while Dortmund is undefeated in six career starts including the Santa Anita Derby earlier this month.

Baffert is proud of both thoroughbreds and considers himself lucky to train them, and he doesn’t seem to play favorites.

"They're both outstanding 3-year-olds, and I just feel so fortunate. I can't believe I have two horses like that the same year," Baffert said to The Herald-Leader. "They're two different types of horses. (Jockey) Martin (Garcia) works them both, and it's really hard to separate them because they move differently. American Pharoah, he's brilliant. The way he moves, he does it effortlessly. Dortmund, he's big, long, and he's really light on his feet.

"They don't get hot, and they're just really quiet, gentle horses. I just can't believe how fortunate I am to have these two, the big guns."

The biggest challengers to Baffert’s attempt at a fourth Derby victory mostly come from fellow renowned trainer Todd Pletcher, who will have four contenders in this year’s field including Carpe Diem. The Grade 1 Blue Grass Stakes and Tampa Bay Derby-victor saw his odds move down slightly from 6/1 to 15/2.

Pletcher’s other top contender is Materiality, who’s started only three races but managed to best Florida Derby favorite Upstart with a hard-fought victory at the 1 1/8-mile dirt track last month. But the win hasn't convinced odds makers yet with Materiality moving from 9/1 to 12/1.
