Angry creditors have thrown plans for an Aug. 4 auction of the Texas Rangers into jeopardy, saying they don't like the bidding procedures and arguing that the lease for the team's ballpark should be severed from the sale.

U.S. Bankruptcy Judge D. Michael Lynn on Monday granted a motion to seal the creditors' request to reconsider the bidding procedures that are heavily controlled by Major League Baseball. Lynn approved the procedures last week after making some changes, including delaying the auction for two weeks to give potential buyers more time to secure financing.

Attorneys for Major League Baseball said the creditors' motion filed last week was rehashing arguments already rejected by the judge, including claims that the bidding process would prevent a fair and competitive sale.

Lynn set a Tuesday hearing to consider the objections and possibly rule on a separate lawsuit, filed by creditor JP Morgan Chase Bank, seeking to remove the Rangers Ballpark lease from the sale.

JP Morgan contends the team's parent company, Hicks Sports Group, transferred the lease to the team just before the bankruptcy filing without the bank's approval, as required in its loan agreement. The bank contends that the ballpark lease is not the team's property.
