CHICAGO — Jed Hoyer was introduced as the Chicago Cubs new general manager Tuesday, joining Theo Epstein in a partnership they hope can bring a World Series championship to a team without one since 1908.

Hoyer left the San Diego Padres after two years as their GM. Also coming to the Cubs from the Padres was assistant GM Jason McLeod, who also worked with Hoyer and Epstein in Boston where they helped the Red Sox win championships in 2004 and 2007.

McLeod will be in charge of scouting and player development for the Cubs. Epstein was introduced as director of baseball operations last week after leaving the Red Sox with a year to go on his contract.

Hoyer is the 15th GM in Cubs history.

Hoyer was the Padres GM the last two seasons. The Padres went 90-72 in 2010, leading the NL West for much of the season before stumbling in September and missing the playoffs. After Hoyer traded three-time All-Star slugger Adrian Gonzalez to the Red Sox and Epstein for three prospects and outfielder Eric Patterson in December, the Padres struggled badly and finished last in the division at 71-91.

A former college baseball player at Wesleyan College where he pitched and played various positions, Hoyer later returned to the school as an assistant coach.

During his eight seasons with the Red Sox, part of which he served as an assistant under Epstein, he helped Boston win World Series titles in 2004 and 2007. Hoyer had a brief 44-day stint as a co-general manager when Epstein briefly left the organization.

Hoyer said winning the championship in 2004 to end an 86-year drought was something that he would never forget.

Josh Byrnes was promoted to GM in San Diego to replace Hoyer.

“As I told Tom Ricketts when he first called, if we didn’t have Josh Byrnes in town, you wouldn’t even be having a discussion with Jed Hoyer,” Padres CEO Jeff Moorad said, referring to the Cubs owner. “But because of the relationships that exist among all involved, Jason, Jed, Theo, Josh, this is in my view a feel-good result that allows people to continue achieving their dream in the great game that we are part of, baseball in America.”

Epstein said he and Hoyer met with manager Mike Quade last week for six or seven hours and that a decision whether to retain him for the final year of his contract could come within the week.

He also said that although anything is possible, it’s likely third baseman Aramis Ramirez will end up with another team. The Cubs exercised their portion of a $16 million mutual option but Ramirez declined it and became a free agent. He is looking for a multi-year deal.

On the matter of the drawn-out compensation issue between the Red Sox and Cubs for Epstein leaving, Epstein said it would either be turned over to Major League Baseball at the end of the day Tuesday or there might be an extension to work it out.

McLeod, who started his front office career as an intern in the Padres baseball operations department in 1994, worked with San Diego in various positions before joining the Red Sox in 2003.

McLeod was appointed director of amateur scouting after the 2004 season and his first draft produced star second baseman Dustin Pedroia.
