Matt White: Relief Pitcher. Non-Roster Invitee. Billionaire.

Matt White, a 27-year-old lefty reliever who's played a grand total of two non-consecutive seasons in Major League baseball and possesses a career ERA of 16.76, may shortly become one of the richest men in pro sports--richer than Tiger Woods, richer than Michael Jordan, richer, even, than Martha Stewart.

Three years ago, the AP reports, White bought a fifty-acre parcel of land for $50,000 from an elderly aunt in need of fast cash. A surveyor subsequently informed him that the parcel sits on 24 million tons of high-quality, quarryable stone. At $100 per ton, that works out to $2 billion, though the costs involved in mining it would likely reduce its market value to (according to one expert quoted in the piece) "several million dollars, or more."

White has put the property on the block and turned his attention to winning a roster spot with the Los Angeles Dodgers. His chances are not great.
