(CBS) The Cubs made official Friday what was known earlier in the week.

Two days after signing president of baseball operations Theo Epstein to a five-year extension, the Cubs also extended the contracts of general manager Jed Hoyer and senior vice president of scouting and player development Jason McLeod along the same timeline. That keeps Epstein, Hoyer and McLeod under contract through 2021.

“Jed and Jason are simply the best at what they do and have played fundamentally important leadership roles in helping the Cubs build a healthy and thriving organization,” Epstein said in a statement. “We feel honored to have the stability and support that we enjoy throughout baseball operations and look forward to many years of working together in Chicago.”

Hoyer and McLeod both joined the Cubs on Nov. 1, 2011, shortly after Epstein had been hired. They’ve been instrumental in taking the Cubs from a 101-loss season in 2012 to a 101-win season this year.

Hoyer and McLeod have been working together since 2003, across stints with the Red Sox, Padres and Cubs.

Both Hoyer and McLeod have had opportunities to take promotions with other organizations but declined in their quest to help bring the Cubs their first World Series title since 1908. The language of Hoyer’s contract wouldn’t be prohibitive for him to potentially take a promotion elsewhere, he told 670 The Score on Thursday, while also emphasizing that his heart is in Chicago.
