Mike Trout Lifetime Contract: The 10 Biggest Deals in Sports History

Mike Trout looks set to sign the largest contract in professional sports history. ESPN reported Tuesday that the center fielder will pen a 12-year deal with the Los Angeles Angels worth an eye-watering $430 million.

The 27-year-old was slated to become a free agent in 2020 but the Angels have moved quickly to take him off the market by offering him a 10-year extension on top of the two remaining years on Trout's current six-year, $144.5 million deal.

The New Jersey native, who won the American League MVP award in 2014 and 2016 and finished second four other times in the voting, has spent his whole MLB career with the Angels and if he sees through his extension he's unlikely to ever play for another franchise.

The Angels, however, will hope to get a better return for their investment than they did when they signed Albert Pujols and Josh Hamilton to long-term deals. The former agreed a 10-year, $240 million deal in 2011, but has since failed to live up to expectations.

Hamilton, meanwhile, signed a five-year deal worth $125 million in December 2012, but was traded to the Texas Rangers less than three years later.

Trout is set to earn an average of almost $36 million a year. That breaks the current record for an average annual salary, which had been held by Zack Greinke since the pitcher signed a six-year extension with the Arizona Diamondbacks in 2016.

Greinke pockets an average yearly salary of $34.4 million, but Trout will beat that and will also set a new record for the richest contract ever signed in the history of professional sports across the world.

To put Trout's new contract into context, the deal is 30 percent larger than the one Bryce Harper signed at the beginning of the month with the Philadelphia Phillies.

At the time of signing, Harper's 13-year, $330 million deal was the biggest ever in the history of sports in North America. However, the record now belongs to Trout, who also beat the five-year deal worth $365 million that boxer Canelo Alvarez signed with broadcaster DAZN.

With the exception of the latter's deal, baseball accounts for nine of the 10 richest contracts ever signed in world sports.

Trout and Harper occupy two of the top three places, followed by Giancarlo Stanton's 13-year, $330 million deal with the Miami Marlins and by Manny Machado's $325 million contract with the San Diego Padres, which was signed in February.

Alex Rodriguez features twice in the top 10, with his $275 million deal with the New York Yankees trumping the $252 million contract he had penned with the Texas Rangers. Both contracts were 10-year long, while Nolan Arendo will earn $260 million over eight years after signing an extension with the Colorado Rockies earlier this year.

In 2016, Miguel Cabrera extended his stay with the Detroit Tigers by the same amount of time and will earn $247 million until 2023, while Robinson Cano and Pujols round up the top 10 with decade-long deals worth $240 million each.
