Richest Sports Owner Stakes Claim in Diamondbacks

Rob Walton, worth nearly $146 billion according to Forbes, acquired his minority stake in the Diamondbacks at a $2 billion franchise valuation. The proceeds are expected to fund Chase Field renovations, with the team committing $250 million toward ballpark improvements.

The 81-year-old son of Walmart founder Sam Walton is a limited partner with no decision-making responsibilities, according to a source. Team president Derrick Hall had previously indicated the possibility of bringing in additional investors for ballpark projects.
