Synonym discussion
Sense: noun/1
A 'pop fly' and a 'popup' are nearly identical — both describe a ball hit high but short. 'Popup' is more informal and is also used as a verb ('he popped up'). 'Fly ball' is the broader category: any ball hit into the air, including deep hits to the outfield. A pop fly is a specific type of fly ball that stays close to the infield. 'Infield fly' is a legal ruling under baseball's infield fly rule, not a description of the ball's trajectory — though it applies to pop flies in certain situations. Finally, a 'line drive' is the opposite: a ball hit hard and low through the infield, not high enough to be a fly ball. For example: 'A pop fly to shallow center field was caught, but a line drive to the gap went for a double.'
Common collocations
Etymology
'Pop fly' is a compound noun from American baseball slang dating back to the late 1800s. The 'pop' part echoes the short, crisp sound of a bat making contact with the ball on a light swing, while 'fly' (short for 'fly ball') refers to a ball hit through the air. Together they describe a hit that goes up high but stays close — the opposite of a 'line drive' or a 'home run.'
