Most Strikeouts in MLB History
A strikeout is one of the most intense battles in baseball where the pitcher comes out on top against the hitter. In baseball, a strikeout occurs when the batter receives three strikes during their turn at the plate. This means they are out unless the catcher fails to catch the third strike, in which case the batter can attempt to run to first base. Nolan Ryan holds the record for the most strikeouts in MLB history with 5,714 career strikeouts, far ahead of legends like Randy Johnson and Roger Clemens.
