GRAND RAPIDS (WKZO) -- Tennis star Andy Roddick is suing Miracle Match Foundation of Grand Rapids for 100-thousand dollars.

A U.S. Bankruptcy Trustee alleges Bill Przybysz is running a Ponzi scheme through the foundation.  Roddick's lawsuit alleges two checks bounced last fall, and were payment for his appearance at an event in Connecticut last September.

A Grand Rapids family says the charity also owes them 50-thousand dollars for an event nine years ago.
