Kentucky Derby odds: Classic Empire, Always Dreaming among early betting favorites

With the 143rd Kentucky Derby just around the corner, oddsmakers have already set the lines and released early predictions about the favorites to win this year's race.

After Nyquist unsurprisingly took the trophy in 2016, this year's Derby odds are more uncertain. While Classic Empire and Always Dreaming are the early betting favorites to win the G1 series this coming Saturday, horse injuries and lack of pattern in build-up race winners have positioned this year's Derby predictions as more of a guessing game.

"I think it's as wide open as we've seen in a long time," trainer Dale Romans said of this year's event to the Los Angeles Times. "...It could be any horse in this race."
