San Francisco, CA (SportsNetwork.com) - Just days before the San Francisco Giants begin another World Series title defense, the team has rewarded manager Bruce Bochy and general manager Brian Sabean with contract extensions.

Although terms of the deals were not disclosed, the extensions will keep both under contract through the 2019 season. Sabean, in addition, was promoted to executive vice president of baseball operations and Bobby Evans was named general manager.

The Giants previously gave Bochy and Sabean extensions through 2016 after last winning the World Series in 2012. The two have led San Francisco to three World Series titles in the last five years.

"Brian and Bruce form the foundation on which all three championship teams have been built," said Giants president and CEO Larry Baer on Friday. "The strength and stability of Giants baseball is a direct reflection of the strength and stability of the partnership of these two men. My top priority this offseason was to ensure that this partnership and our outstanding baseball organization remain intact for years to come."

Bochy has been the Giants' manager since 2007 and has posted a record of 667-629 in nine seasons. He previously guided San Diego for 12 years, leading the Padres to the 1998 World Series, and owns a career mark of 1,618-1604.

"There is no place I'd rather be than right here in San Francisco with the Giants," said Bochy. "I couldn't have a better situation. I am extremely proud to be a part of this great franchise and I look forward to continuing to work with everyone in the organization to build on the success of the last several years."

Sabean is entering his 23rd year with the Giants and 19th in charge of the baseball operations. In his expanded duties, he will manage all aspects of the Giants' baseball department.

"I want to thank Larry and the ownership group for their commitment to me and to our entire baseball department," said Sabean, currently the longest-tenured GM in baseball. "I am thrilled that our group will remain together for the foreseeable future."

The group now includes a bigger role for Evans, who will enter his 22nd year with the Giants. He had been the assistant GM and will continue to assist Sabean in all baseball decisions.

"Bobby and I have worked together for more than two decades, and he has excelled at every aspect of his job," Sabean continued. "I have the utmost confidence in his ability to handle the daily activities of baseball operations."

The Giants will open the 2015 season Monday in Arizona.
