The Top 10 Most Lucrative Contracts in American Sports

Nine of the top-10 slots are filled by monster MLB contracts.

Some of baseball's biggest stars are inking massive contracts this offseason, with superstar free agent Bryce Harper taking home the biggest deal. After waiting all offseason and through the start of spring training, Harper and the Phillies reportedly agreed to an astounding 13-year, $330 million deal on Thursday.

Recently, Manny Machado signed a monster 10-year, $300 million contract with the Padres and Nolan Arenado locked down an eight-year, $260 million extension with the Rockies.

While Harper and Machado's contracts are certainly historic, they're not the first megadeals to be signed. Both players join several other sports stars as some of America's highest-paid athletes (and that doesn't include endorsement deals).

Take a look at the world's top-10 highest-paid American athletes by contract:

1) Mike Trout: $430 million

2) Bryce Harper: $330 million

Harper, 26, reportedly agreed to a record-breaking 13-year, $330 million contract with the Phillies. It reportedly includes no opt-outs and a full no-trade clause, meaning Harper will play in Philadelphia until 2032. The 2015 NL MVP becomes the highest-paid MLB player by total value. However, Harper's average annual value of $25.4 million is lower than Machado's ($30 million) since his contract is three years longer.

3) Giancarlo Stanton: $325 million
