On March 27, 2009, Matsuzaka reported to Red Sox spring training only twelve days before opening day. In Matsuzaka's first start of the regular season, he gave up three home runs against the Tampa Bay Rays, ultimately losing the game. In his next game against the Oakland Athletics, Matsuzaka only lasted one inning, giving up five hits, five runs, two walks, and striking out none. Matsuzaka was quickly placed on the DL, while reliever Justin Masterson took his spot in the rotation.
