Hot on the heels of Friday morning's announcement that Jerez will join the World Superbike calendar, America's Laguna Seca circuit has now revealed it will also return for 2013.

Like Jerez, a three-year deal with Laguna Seca has been agreed by WSBK. The 2013 round will take place on 27-29 September.

"We are thrilled to have World Superbike commit to a three-year race schedule at Mazda Raceway and the Monterey Peninsula," said Gill Campbell, Laguna Seca CEO/general manager.

"We have a strong history together and their return solidifies our position as THE premier circuit in the U.S. for motorcycle racing."

World Superbike was a popular fixture at Laguna Seca until MotoGP returned to the track in 2005. Both championships will now race at the famous Californian venue - featuring the Corkscrew turn - next season, with MotoGP on July 19-21.

"We are absolutely delighted to be returning to Mazda Raceway Laguna Seca for the U.S. round for the first time since 2004," said Paolo Flammini, CEO of Infront Motor Sports.

"Over the period in which we were last there, we witnessed an extraordinary growth in interest and in overall attendance and we are sure that this event will once again become one of the most prestigious on the calendar, with six manufacturers competing.

"The return of Mazda Raceway to the Superbike World Championship calendar will definitely be a boost to the championship's growth in the U.S. market as California has a special tradition and offers significant opportunities for the motorcycle industry, sponsors and media."

It was not announced if the Laguna Seca WSBK weekend will also include the World Supersport Championship. This was previously not the case, just as only the MotoGP class is present for the grand prix.

Laguna Seca's WSBK return casts doubt on the exisiting US event at Miller Motorsports Park in Utah. The provisional 2013 WSBK calendar is yet to be announced.
