The 2012 season started with losses for the Hawks. During the off season, they lost their star starters Tsuyoshi Wada (to the Baltimore Orioles), Toshiya Sugiuchi and D.J. Houlton (to Yomiuri Giants) through free agency. All star shortstop Munenori Kawasaki also left the team for the Seattle Mariners. Closer Takahiro Mahara would sit out the season through injury. To compensate for these losses, the team acquired outfielder Wily Mo Peña and starter Brad Penny from MLB, in addition to starter Kazuyuki Hoashi from Seibu Lions. However, of the 3 major signings, only Peña made regular contributions. Hoashi and Penny made two starts combined in 2012, as Hoashi missed almost the entire season with an injury and Penny was released.
