The six-time NBA champion is now a billionaire, one of four NBA owners to make the annual Forbes world list of billionaires. Clippers owner Steve Ballmer ($21.5 billion), Rockets owner Leslie Alexander, with a net worth of $1.6 billion, and Bulls owner Jerry Reinsdorf, worth $1.3 billion, are also on the list.

Harrington, who lost his card last year and needed a sponsor’s exemption to get into the tournament, is now eligible for the Masters, the Players Championship and at least two World Golf Championships.
