    After the fall of Lehman Brothers, Joe Peta needed a new employer. He found a new job in New York City but lost that, too, when an ambulance mowed him down as he crossed the street on foot.

In search of a way to cheer himself up while he recuperated in a wheelchair, Peta started watching baseball again, as he had growing up. That's when inspiration hit: Why not apply his outstanding risk-analysis skills to improve on sabermetrics, the method made famous by Moneyball--and beat the only market in town, the Vegas betting line? Why not treat MLB like the S&P 500?

In his book, Trading Bases: A Story About Wall Street, Gambling, and Baseball (Not Necessarily in That Order), Peta shows how to subtract luck from a team's statistics to best predict how it will perform in the next game and over the whole season. His baseball "hedge fund" returned an astounding 41 percent in 2011-- with daily volatility similar to funds he used to trade for.
