The Ricketts family officially assumed control of the Cubs on Tuesday upon the closing of its $845 million deal with the Tribune Co.

The sale allows Tribune, which has owned the franchise since 1981, to retain a five percent stake in the team to reduce taxes by an estimated $300 million.

Tribune paid $20.5 million for the Cubs in 1981.

"My family and I are thrilled that this day has finally come, and we thank commissioner Bud Selig and Major League Baseball owners for approving our ownership," Tom Ricketts said in a released statement. "Now we will go to work building the championship tradition that all Cubs fans so richly deserve."
