Major League Baseball owners approved the sale of the San Diego Padres on Thursday to a group that includes the O'Malley family and pro golfer Phil Mickelson. Commissioner Bud Selig announced the endorsement after the conclusion of the owners meetings in Denver. Under the deal, the group will buy the franchise from John Moores for around $800 million. The final closing of the sale will be on or before Aug. 31. The new ownership group includes Kevin and Brian O'Malley, the sons of former Los Angeles Dodgers owner Peter O'Malley. Peter and Tom Seidler -- the nephews of Peter O'Malley -- also will be involved in the deal. Two of the four are expected to move to San Diego.
