Country House was declared the winner of Saturday's Kentucky Derby at Churchill Downs after the second disqualification in the race's 145-year history. Maximum Security crossed the finish line first in 2:03.93 but was moved to 17th place after a lengthy review.

Many in the rain-soaked crowd of 150,729 booed the result. Connections of Maximum Security celebrated in the winner's circle but were quickly escorted out, replaced by Country House's connections.

As the race stewards reviewed the video, Country House trainer Bill Mott stood in the middle of the sloppy Churchill track, surrounded by reporters.

"They don't take many horses down in the Kentucky Derby," Mott said before the disqualification was announced. "If it was a maiden $10,000 on a Thursday, it would be a no-brainer. They don't want the controversy, I'm sure, but you're supposed to keep a straight line."
