Houston ? The Houston Astros will dismantle one of the four largest remaining signs bearing the former Enron Field tag today.

The Astros bought back the naming rights to their downtown Houston ballpark Feb. 27. They paid about $2.1 million to take back the stadium’s naming rights from Enron, the energy company that went bankrupt in December.

The Astros regained the right to immediately negotiate a naming rights agreement with a new partner.

Many of the references to Enron Field have already been removed.

The stadium will be called Astros Field until a new naming rights sponsor is selected.
