What is a Can of Corn in Baseball? Definition and Origin
A 'can of corn' is old baseball slang for a high, easy-to-catch fly ball hit to the outfield.
What is a Can of Corn?
A "can of corn" is classic baseball slang used to describe a high, lazy fly ball that is exceptionally easy for an outfielder to catch. When a batter hits a can of corn, the result is almost always a routine out. The term dates back to the early 20th century and is deeply embedded in the culture of the game, frequently used by broadcasters when a hitter pops up weakly to shallow outfield territory.
How It Is Measured
While "can of corn" is a subjective, qualitative term, modern Statcast data allows us to quantify exactly what makes a fly ball "easy." The metric used is Catch Probability. Catch probability is calculated based on two variables: the distance an outfielder must travel to reach the ball and the time they have to get there.
A can of corn typically registers as a 95% to 100% catch probability. The fielder rarely has to move more than a few steps, and the ball spends a long time in the air. Statcast also tracks Hang Time. A routine pop-up might stay in the air for five to six seconds, giving the fielder ample time to camp under it.
Worked Example
Imagine New York Yankees outfielder Aaron Judge hitting a towering pop-up to shallow right-center field. The ball comes off the bat at a steep Launch Angle (around 65 degrees) and an Exit Velocity of only 78 mph.
Because the ball is hit almost straight up, it stays in the air for 5.8 seconds. The outfielder only needs to jog 30 feet to reach the landing spot. According to Statcast's catch probability model, this specific batted ball has a 99% catch probability. The outfielder settles under it, makes the catch with ease, and the broadcaster casually remarks, "He popped it up—a routine can of corn."
Why It Matters
While the term itself is lighthearted, the concept matters for understanding batted ball profiles. For hitters, a can of corn represents a wasted at-bat, often the result of failing to recognize a pitch or getting jammed inside. For pitchers, generating weak fly balls is a core strategy to avoid Hard-Hit Rate line drives and home runs.
In the context of Legends Deck and card simulation, understanding a player's batted ball profile—specifically their Fly Ball Rate versus their line drive rate—helps predict how often they produce easy outs versus extra-base hits. A player who hits a high volume of weak fly balls is a liability, while a pitcher who induces them is highly valuable.
Limitations / Common Misconceptions
The most common misconception is the origin of the phrase. Many fans assume it relates to agriculture or cornfields, but it actually comes from 19th-century grocery stores. Store clerks would stack canned goods on high shelves. To retrieve a can of corn, the clerk would use a stick to knock it off the shelf and easily catch it as it dropped—a simple, effortless catch, much like the fly ball.
Another limitation is assuming all high fly balls are easy outs. The wind, stadium architecture (like the famous Crawford Boxes in Houston), and stadium lighting can turn an ordinary can of corn into a difficult,甚至 dangerous play for an outfielder.
