The 2009 Yokohama BayStars season features the BayStars quest to win their first Central League title since 1998. The team made a bit of a splash just before the season, signing former Hokkaido Nippon Ham Fighters starter Ryan Glynn to shore up their rotation, led by veterans Daisuke Miura and Hayato Terahara. On the offensive side, the 'Stars picked up Dan Johnson, a journeyman minor leaguer, to give protection to 2008 batting champion Seiichi Uchikawa and slugging third baseman Shuichi Murata.
