Nexen Tire has extended its sponsorship of Korean Baseball Organisation (KBO) League side Nexen Heroes for the next three years.

Nexen first became the Seoul-based club’s main sponsor in 2010, signing a six-year deal. Though financial details of the deal have not been disclosed, reports indicate it is worth 10 billion won (US$8.79 million) a year - around double the value of the previous deal.

The Heroes replaced the bankrupt Hyundai Unicorns in the KBO – the top tier of professional baseball in South Korea - in 2008. Since joining they have been the league's only club without corporate ownership, surviving instead by selling naming rights to the club.

"I'd like to thank Nexen Tire for agreeing to extend our sponsorship deal," said the Heroes' chief executive Lee Jang-seok. "I am so grateful for the interest and concerns expressed by our fans in our negotiating process.”



The Nexen Heroes will move into the brand new Gocheok Sky Dome starting next season.
