Matsuzaka made his next start on May 22, 2009, against the New York Mets after being activated off the DL. He gave up five runs over five innings, receiving another loss. Matsuzaka gained his first win of the season against the Detroit Tigers on June 2, 2009, but failed to produce any quality starts. After a loss against the Atlanta Braves on June 19, 2009, Matsuzaka was once again placed on the disabled list. Red Sox manager Terry Francona stated that Matsuzaka was placed on the DL due to "weakness" in his throwing arm possibly caused by the extensive pitching he did in the World Baseball Classic. Francona also made it clear that it would not be a "two-week DL" stating "We're going to have to figure this out. We have a lot of work ahead of us trying to get him back to being Daisuke."
