If you believe that Tyler Duffey will have a long and successful career then you can invest in his future. http://www.mlbtraderumors.com/2016/04/fantex-franco-schoop-mchugh-duffey-solarte.html "Fantex offers professional athletes an up-front, one-time payment in exchange for a portion of that player’s future earnings both on and off the field. Fantex then sells “shares” of that player to public investors for a set price (thus covering the up-front payment to the player), allowing those investors to turn a profit if said player crosses a certain threshold in his career earnings." Based on some rough math, Duffey will need to earn more than $25 million for this to pay off. If you don't like that bet, it sounds like other bets may become available: "With six big leaguers now on board in addition to 14 athletes from other sports, it stands to reason that the number of professional baseball players willing to enter into such agreements will increase. It’s an interesting proposition for Major Leaguers — not entirely dissimilar from agreeing to an early contract extension; in essence, the players in question are taking a life-changing sum of money early in their career in exchange for limiting their earning capacity once they’ve navigated through their arbitration years and entered their free-agent seasons." If there is any truth to the speculation that Sano has spent most of his bonus money, maybe he will be next. What would investors be willing to pay for 10% of Sano's future earnings? And how will this affect baseball in general? One final quote from the article: "Beyond the long-term impact on a player’s earnings, it also seems plausible that players who enter into agreements with Fantex could be less likely to sign long-term extensions with their current club."
