9 innings is a Dutch baseball blog focused on the sport, its traditions, and the people and decisions shaping it. Run by writer Ronald Bouwman, the site presents opinion, commentary, and analysis for readers who care about baseball in the Netherlands and beyond. Its name reflects a clear affection for the traditional nine-inning game, and the blog has discussed efforts to change rules for grassroots baseball, including proposals to replace full games with time-limited play.

Coverage spans Dutch baseball, the national team, tournaments such as the Honkbalweek Haarlem, and developments involving clubs and youth competitions. Articles also consider coaching choices, game atmosphere, league standards, and the use of data and analytics. Alongside match-related perspectives, the site features observations from the stands and reflections on baseball culture and history. The archive contains years of posts, offering an ongoing, personal take on the sport rather than commercial products or services. 9 innings is a place for informed, candid discussion about how baseball is played and what makes the game worth following.
