VIENNA (AP)—The ATP tour event known for 25 years as Tennis Trophy will be renamed the Erste Bank Open after longtime sponsor Bank Austria pulled out.

The sponsor pulled out after tournament venue Wiener Stadthalle announced a sponsorship deal with main business rival Erste Bank.

Tournament director Herwig Straka said Wednesday that “the change of the main sponsor after a quarter century marks the start of a new era for the event.”

The 37th edition of the $650,000 indoor hard-court event is scheduled for Oct. 23-31.
