5. Prince Fielder - $214,000,000
Following the 2011 season and World Series, the Milwaukee Brewers first baseman Prince Fielder was hot property. He had just been named an All-Star for the third time, been named MVP in the all-star game itself and won his second Silver Slugger award.
But now he was a free agent, and organizations could finally make their move for the Ontario, California native.
And it was the Detroit Tigers who got their man. And they paid a handsome $214 million over the course of nine years for the privilege. It didn't go too smoothly for the Tigers though.
After two disappointing seasons, Fielder was traded away to the Texas Rangers in November 2013.
Fielder was incredibly invisible in the playoffs against Billy Beane's Oakland A's. He batted .278 in the ALDS against Oakland, registering 5 hits and 0 RBIs. In the 2013 ALCS he was even worse, registering a .182 average with only 4 hits and 0 RBIs.
That was the straw that broke the camels back as far as Detroit head office was concerned, and they got rid of Fielder and his potentially toxic contract which had $168m still to pay up until the player would reach 36.
It was a gamble that didn't pay off for the Lions, but it seems like it could become Texas' problem now.
