This post was first published early in 2016 to identify batteries (pitcher and catcher) with 200 or more regular season starts together. It is based on the Defensive Lineups pages for each team and season on Baseball-Reference.com. At that time (early 2016), those seasons only went back to 1914, whereas now (in early 2021) there are data for the entire modern era, back to 1901.

As I’ve received several queries about this article, I decided to update it to include the 1901-13 seasons and also, of course, the 2016-20 seasons as well. Doing so has increased the number of qualifying batteries from the original 26 up to 35 for the entire modern era. More on these long-term batteries is after the jump.
