The Matsuzaka Generation (松坂世代 Matsuzaka Sedai) is a term used to collectively describe the (usually Japanese) baseball players that belong to current Chunichi Dragons starting pitcher Daisuke Matsuzaka's age group. As per Japanese laws on how children are to be divided into grade levels, this term refers to players born between April 2, 1980, and April 1, 1981.
The term was coined by the Japanese media as the age group that came to be known as one of the deepest and most talented in Japanese professional baseball history.
