Cubs executive Theo Epstein agrees to 5-year extension with club

— -- The Chicago Cubs and president of baseball operations Theo Epstein have agreed to a five-year contract extension.

Terms of the deal were not disclosed.

Epstein's initial contract was set to expire at the end of this season, and his status was one of the few unanswered questions of the Cubs' season so far.

The NL Central Division champs are cruising to finish the season with the best record in baseball by a wide margin. They head into the postseason as a team without a glaring weakness: great offense, stellar defense, outstanding rotation, the best relief corps in baseball and a canny manager in Joe Maddon.

Their 100-and-counting wins this season marks the first the time club has broken the century mark since 1935.

"In the five years under Theo's leadership, he has brought in a strong executive team and acquired and developed some of the best players in the game. Now, the results are on the field. My family and I have no doubt that we have moved closer to our goal of delivering Cubs fans the World Series Championship they deserve," team chairman Tom Ricketts said.

Epstein was a former front-office man for the Boston Red Sox?-- becoming the youngest general manager in MLB history in 2002 -- and is widely credited with building the squads that won the 2004 and 2007 World Series.?

Epstein resigned from Boston in 2011 and signed a five-year deal worth $18.5 million to become President of Baseball Operations for the Chicago Cubs. In Epstein's first three years at Wrigley, the team finished in last place in the NL Central. Last season, they advanced to NLCS as a wildcard team but were swept by the New York Mets.?
