A "can of corn" is a high fly ball to an outfielder that is caught easily and routinely.
The most accepted theory is that the phrase, 1st used in 1896, makes reference to a long-ago practice where a grocer would use a stick to tip a can off a high shelf, then catch it in his hands or outstretched apron.
The term "Can of Corn" is a phraise used to describe a softly hit Baseball, as it could easily be caught. The term originated as a customer would ask a grocery clerk for a can of corn the store clerk would grab a can from the top of a stack of cans, and would softly toss the can down to be caught without harm.
