Hannemann racked up four extra-base hits -- including a grand slam -- for Double-A Tennessee on Saturday. The 24-year-old Hannemann is lost in the shuffle in a deep Cubs farm system, and probably profiles as little more than a reserve outfielder once he arrives in the big leagues. He's hit just 11 homers across 759 minor-league at-bats and is slashing .207/.258/.321 since earning his promotion to Double-A in April.
