The New York Yankees star says bidders aren't required to pay money still owed to him and some other former Rangers.
Six years after he was traded, Rodriguez is owed $24.9 million in deferred compensation.
Rodriguez's motion was among a dozen or so objections filed Wednesday, most by creditors.
An auction to sell the Rangers is set for next week. The starting bid is from a group led by Hall of Fame pitcher Nolan Ryan and lawyer Chuck Greenberg, whose plan to buy the Rangers has been stalled for months.
Their $575 million bid includes paying the full $204 million owed to A-Rod and other unsecured creditors.
