A random/bad infield hop made by a ground ball in the game of baseball or softball. Named after the softball fields in West Lafayette, Indiana, which are known for their propensity to produce bad hops due to having low maintenance gravel instead of actual dirt infields.
The fields are at the corner of Salisbury and Cumberland Avenues, and are unofficially known as the Salisbury Fields, though the official name is Arni Cohen Memorial Fields.
When it happens in your favor: "Yes, that was the Salisbury Hop we needed!"
When it happens against you: "God damn fucking Salisbury Hop cost us the game!"
