The Cubs are adding Austin Jackson for the stretch run, acquiring the veteran outfielder and cash from the Seattle Mariners on Monday for a player to be named later and an international-signing slot.
Jackson plays center and hits right-handed, giving manager Joe Maddon another option with Jorge Soler (oblique) on the disabled list and a young lineup experiencing the pressure of September for the first time.
Jackson was hitting .272 with eight homers, 38 RBIs, 15 stolen bases and a .699 OPS in 107 games for Seattle.
Jackson, 28, is positioned to become a free agent after this season.
